This is more about providing hard numbers for existing builds and less about concept, but the concept is simple: You can always do this on your own by adding two reliable sets of GPU and CPU-only numbers (not total load numbers), then adding some buffer for other parts. In that sense, you don't really need a power supply calculator and can probably do it more accurately on your own.
Methodology used stems from our CPU & GPU testing methods (published earlier in the year in our methodology pieces -- it's all the same parts). We describe verbally in this content whether we're using CPU or GPU graphics settings. Motherboard was a Z490 Maximus XII Extreme for Intel, X570 Master for AMD. The VRM efficiency will impact power needs as well, but ultimately, it's the GPU and CPU driving most of the power in the standard gaming PC. You will need to consider hard drive power consumption if running a large storage array.
Making a sweeping generalization here, we've noticed that a lot of people over-buy their power supply needs, and we'd assume that's because it's the safe thing to do. That is, "safe" with regard to ensuring no issues arise from buying too close to the PSU capacity. It's also the safe thing to do when you don't really know how to measure power supply needs. For the most part, you can take our component-level reviews (e.g. 10900K or 3900X review, or similar, and a 2080 Ti review, or similar) and add the two major parts' individual power consumption numbers to approximate the bulk of the PSU needs under full load. That's because we don't test total system power consumption for component reviews, but rather the power needs of that one component. In the instance of this specific video, though, we are using total system power consumption, and we're using that to measure the performance of a few builds we think are likely to occur in the 'wild.' That said, if you have minor component differences, you really should just be looking at power consumption numbers on a per-component basis and roughly adding things together. Or, if looking at the systems outlined in this video, you can extrapolate the jump between one CPU or GPU and the next and approximate the power needs much more accurately. Rather than using a "PSU calculator," we think you should just actually do your own calculation by using data provided. In this instance, however, we've done most the legwork for common configurations to answer the question of how many watts are needed for a gaming or workstation PC's PSU.

the human eye can only see 450 watts in bronze colors so anything more than that is overkill.

Yes, absolutely. New Components like DDR5 - albeit not very power intensive - have been added as well. So a newly painted picture would be great!
@@Leonardo-wn2fp DDR5 consumes less power than DDR4 actually, but the amount is very small to begin with.
@@AlexanderMichelson Thanks! Good to know :)
Would be nice to see what happen if you ACTUALLY use a good PSU under high load, let's say use a 600W with in a real scenario for a high end system... will it shutdown? be ineficient or simply good enough? Asking because I got a 850W which may never be used unless I got a top high end CPU and GPU, which may not happen but I gave this extra headroom for future use as some of those have 10 years warranty so why not?
Just subtract the power usage from this video.

This is easy, you need 500W for the actual computer and addition 1300W for fans and RGB lighting. 2000W is overkill.

@European Defenderman Nvidia recommendation doesn't matter at all because they count in all the garbage PSUs that can't even qualify the first 80+ rating, they just make sure that everyone will be able to run it with 750, a 650 with 80+ gold can even run 2 5700XTs, i tested it, these 1k PSUs are just market scam.
They had us in the first half, not gonna lie.
500w is not enough... just the normal cpu and gpu basically level alone would blast over 500w.. 600 to 700 would be better, but i think you shuld move to laptop or those backpack with battary as back up since it would help with the extra power draw...

Your detailed comparisons like this are exactly what I need! This one especially because I was beating myself up about needing more than 650 watts or not for a 5700xt build, and now I know I dont
You don't but it´s useful. Considering the fact that PSUs last for years it's always a smart choice to buy a sightly oversized one as you will be still able to use it with your next build. In many cases the jump from 650w to 750w may cost you $20. And in the long run this will save you a bit of money, too. So, unless you are really on a tight budget, go for the next larger one.
I have been running a 5700XT on 500w since it came out. People always think they need more for some reason.
@@farmeunit me too, everything is good

They probably feel like they had to drop it now because less ethical sources (Linus) are ranting about how you'll need a new power supply for Ampere. Even though Nvidia has already said you won't. Gotta drive clicks.

Snowflake recommends a PSU with at least 2 hamsters inside to generate enough power.
4 hamsters is too much and not efficient.

@@auntiepha8343 have you seen the video? PSU's that high were all in the most cases a overkill before.. so everyone who said it to you was right. Now, it maybe changed. Lucky nothing else.
@@zuga-3938 WTF are you talking about? Have you seen the video? A 750 watt PSU is recomended for the 3000 series card?? RIGHT?! Who said anything about luck? Thanks for making my point for me crystal clear.
@@auntiepha8343 750watt is recommended from nvidia but they even say it themselves, it depends on the whole build and can work with a lower wattage power supply. This 750 is just overkill from them. If you are able to do some math do it yourself and stop yelling kid. You can even use the 3080 if you want (320wattage) plus a low wattage cpu from a ryzen that is like 65watt + add 150w for the rest components you have and you will not even reach 550watt so you will be PERFECTLY fine even with a 600 psu. Especially for the 3070 which has like 100 less wattage use
And everything before.. for example with the 2080ti.. didn't even needed 600watt, ever. So again, yes BEFORE your 750watt psu was overkill for a lot, just as everyone and always told you. No one could have seen it coming that 600-750w psu's with new cards like that could be the "optimal" range in the future so yes luck. 750 is maybe if you have a lot of extra shit and a huge water cooling system a good thing to be "safe" or if you are lazy to do the easy math about the wattage use.
@@zuga-3938 I am not a kid and you are an idiot. IF you use your PSU correctly. Then you want to overshoot your system wattage by 50% that way you actually get your GOLD rating in usage. My system now with a i7 9700k and a Strix 2070 uses over 350 watts. That's why I bought a 750 watt PSU to future prood my system. Now everyone wants a PSU like mine and they are impossible to find. You don't know how to use a a PSU PERFECTLY by your answer. You push systems to hard on the PSU but go ahead and preach dumbass. Do us both a favor and piss off.

Thanks for the many reviews they help allot!
Great video. I think you could or maybe have, make a video on Watts, Volts, Amps, and basically Ω law. With poor inconsistent power supply, like in the USA, one's wattage can vary considerably. This being the case components can heat-up and performances diminishes quickly or fire occur. Here comes the PSU unit requirement...
power stability before anything,
I like how you guys named the AX1600i "Steve" 5:25
Because its Overkill for the Job? 😉
An internet friend of mine laughed in my face (over disc) when I told him my build and mentioned I had a 750W PSU. He told me I probably couldn't even use half my PC because it was "starved". I tried to explain to him that I test these things myself with a Kill-A-Watt outlet monitor and under load my PC barely hits 500W.
You must have a bangin system, because none of the systems tested in the video even reached 500w.
Who’s your idiot friend
Power consumption has dropped over time. Your friend must be thinking about the past.
Explain to your friend what PSU efficiency curve is.

I was planning on buying a 750W Seasonic PSU for my build - the cost difference for the 850W model was only $1, so I went with the bigger PSU which will allow for more running fanless due to the lower power draw
2017 my old Corsair 500watt ps died. So I splurged on a power supply due to peer pressur. Got the Seasonic ss-860XP 80plus platinum. In all my computer enthusiast history, (first pc was a Tandy1000, x386-20), I have never had such a stable system. And my power goes out least 2-3 times a quarter, more so in spring. It was such a good purchase, I am about to get whole new system, with the AMD5 platform. And I am going to buy a much cheaper 500watt ps new to leave with old system. The Seasonic is moving to the new rig, even though its 6 years old (12 yr warranty).
Like my grand pappy used to say, you should never go cheap on your boots or your bed. Because if you're not in one, you're in the other.
or something.....
@@ckmoore101 Do you mind sharing what your "stable system" is, cpu, gpu and all? I'm torn on whether I should get a new psu when i upgrade so it'd be helpful if you shared your system as a reference point (how much headroom in watts should I give for the PC to feel stable?). Much appreciated.

How the 10600k does? I'm looking for a new build and undecided between the 10600k and the i9-9900k.
One other thing, a higher rated power supply can ride out a power line glitch for longer. The Front End capacitors are larger. We have to put in at 1200W Supply for a 400W system to get 30mS , typical spec is 15mS , but some UPS and power transfer switches are slower than that.
Could you do a video about the most reliable/stable memory brands? Especially when under heavy loads (near max usage/load, 64 gigs, heat, etc). For computers that are typically used for work, art, 3D, music production, video editing, etc. I don't know if there's a way to benchmark these things? Thanks for your consideration. New viewer btw, love your videos!
I bought a platinum Fractal ion power supply for the 10 year warranty at 760w. I knew it was overkill. Not only was it cheaper than many gold psu options at the 600w mark (And importantly in stock where i found it) but they accidentally sent me the 860w version and didnt recall it. I think i did quite well.
I know the feeling. Just built a system with a Corsair RM650X and they sent me a RM750X instead. 😁
Wow nice, wish that happened when I ordered the 660w one due to it being on sale & in stock when I needed a new PSU a few weeks ago lol
Cool. Overkill is subjective. Budget is usually my limit. I always go "overkill" 🤣. I'm a tech snob.
I just ordered my new corsair case and corsair TXM psu. It's supposed to come in a week :(. I already have a case and psu but it needs an upgrade. I got ryzen 5 3600 and rtx 2060 ko too so this was a good vid. So i ended up getting 550w which is plenty.
I bought and received the platinum 760W Fractal ion early in the year. It's delivered no-news-is-good-new silent performance and I have virtually no worries about it supporting whatever realistic upgrades I might do years down the road. The price difference between the 660 W version and the 760 W was negligible, anyway.
Snowflake is clearly naming the AX1600i "Steve"
I bet the PSU doesn't generate as much heat as humans tho.
I just love how Steve said a 250w cpu wouldn't really be a thing and then youtube suggested the 13th Gen Intel video right after 😂
Yeah, cracked me up when he said “250w would be an unreasonable scenario.” Reminded me of the old 16kb of RAM meme.

I have two 1000W PSUs. One is an OCZ Z1000M and the other is an EVGA 1000 G2 Supernova, both are 80+Gold . I have them because I used to run twin R9 Furies on a 990FX motherboard with an FX-8350. I am one of the few that actually used the PSU as intended.
Got myself a 750w corsair rmx because the 850w variant was unreasonably more expensive. Felt a bit anxious that I had shot myself in the foot and not bought a big enough psu until I watched this. Thank you!
Oh nice! I was just wondering about this when it showed up in my notification. Keep putting out the great content.
The lack of low wattage PSUs is crazy when you do a non-gaming build. I recorded my dad's PC as maxing out under 30W from the wall. It has a 400W Bronze PSU because it was the cheapest quality ATX PSU I could find.
I would have loved a power brick or otherwise small/non-ATX mount but it would have added at least 50% the price onto the build for something that was ok to be ugly & bulky.
There are some PSUs for under 120 watt usage in form of an notebook power supply, which you can use for compact builds
my server only pulls 100W, using a seasonic 430watt psu for last 11 years or so. Anything that doesn't have a GPU is pretty much not going to use any power
@@grakpan1233 You're right, I wanted to make it an ultra-compact powerbrick based ITX build but it would have added 50%+ to the build cost.
The way ATX power supplies are made limits “quality” applications below 400W. I.e. the space, cost of components, supply chain, thermal/power efficiencies set the low limit. Also marketing wants to advertise the most they can get away with.
The fact consumer stuff starts at 400w, yet OEM's have access to supplies that range down into the low 200's for wattage (sometimes even less) really says it all in terms of what's actually required.
Great content and advice!
Thank you to make this video, it´s really interesting.

You know it's going to be a good day when they use the exact CPU/GPU combo in their testing that you've been considering buying. Not only that, they're using the same CPU/GPU combo I plan to upgrade to sometimes in the future. Feeling a lot better about the 600W PSU now.
That was so helpful, thank you. I have an 850w PSU and most likely of your numbers I could have gotten a 500-600w PSU.
@Mike Edwards I agree. I rather have to much then barely enough. I've seen weird PC issues come up because the PSU was within range but still not enough.
I love how every time Steve and GN team test something, they more or less do a verbal research paper that you'd expect to find in a University Research lab
and in a world that lacks substance and talk is cheap, it is the verbal research papers which define Gamers Nexus and keep me selecting their videos before anything else.

@@Bossfightmedia Yup agreed ! "For the science" 😁✌✌
Something to note is that according to the official Cybernetics tests of the Seasonic PRIME Ultra 650 Titanium PSU 100% load is considered to be 650W at the output of the PSU, not at the wall, while Steve measured power consumption at the wall. The report considers 100% load to be 649.638W DC and 709.002W AC (dividing the two gives you the PSU efficiency rating of 91.627%).
came here to say that. If your System components need 500W a "500W" PSU will work 100% fine. It will draw more than 500W from your wall thought, that's where the efficiency rating comes into play. A PSU always delivers the advertised wattage to the components, it's the draw that is bigger, not the output that is smaller.
Well, most the time, not always. Some bad ones really won't do the rated number, and more importantly, a lot of PSUs can't do the rated number on one rail (eg 12V). It might say 500, but if it can only do 200 per 12V rail, you're kinda screwed with higher end GPUs. Further, we suggested a slight overbuy to keep the PSU in its peak efficiency range. You don't really want to run 500W at 500W for long, as it also becomes a noise issue.
@@GamersNexus If we take the efficiency correction, half of the configurations will be enough for an honest 450 watts. Like be quiet pure power 450. Even with oc.
Yes - I've actually been running a 3700x w/ 5700XT on a Corsair SF450 PSU (ITX build) flawlessly. Granted, the SF450 is not a budget option - paid around 95$
@@GamersNexus this was also more as a "in a perfect world". I would also suggest anyone to have 100W to spare because if IO, Fans, possibly RGB etc.
I had to replace my psu a couple weeks ago and I actually thought about it. I hot a reasonable 500w case. Realized I never move cables anymore, so I didn't even bother with modular setup. I am happy with my purchase.
Why I watch your videos. You actually give details and real tech specs.
Seeing the 3000 series numbers and seeing the date on this video makes me chuckle.
At least this isn't the 1990's where cheap PSU's meant your system blowing up at some point.
Yes it happened to me once when I was a student.
That can still happen if you buy a $20 600w power supply from some unknown chinese brand, yes, those still exist
back in the day.. you can save money buy case that come with psu... pc back then used a lot less power... nowaday.. my 500 watt never had enough...
Happened to me three years ago, and my PSU was not a $20 PSU
had a customer bring in his pc the other day, got a new psu pc wasnt turning on. as soon as i switched it on, it blew up in my face like a firecracker. toppled two shelves as i fell over.
Happened to me as a kid as well
I've had the same 1000w Coolermaster PSU for over 12 years now
That is an extremely good lifespan on that PSU. Awesome to get repeat use out of it and carry it forward -- reduces e-waste, too!
@@GamersNexus my ax1200i, not as old, but still running since 2013 through 3 rebuilds. So that's about 7 years.
Powering currently a 3950x and Titan X Pascal.
and 9 SSDs internally (i've wondered what wattage they pull to begin with)
although i know the Intel 750 1.2TB AIC one i have is 25 watts at full writing performance.
once you get a solid psu, it is essentially eternal until forced to dump it if ATX standards changes drastically, which I don't see happening anytime soon.
That thing is gonna die any day now, buddy. Most PSUs last about 8-10 years in my experience.
I've had same PSU since Intel Core 2 Duo build , which is like 12-13 years too, but I replaced it this year because I got scared it might damage my components.
I had a Seasonic Gold die after 2 years, I was flabbergasted; so if your Coolermaster has lasted 12 years, you're doing good.
You say we are "criminally over purchasing a psu" but yet you have the AX1600i eye candy right in the video. You sir are an enabler! Now I must have it.
Best thumbnail, just here to upvote it. Carry on
"You really don't need a 1000w..."
Unless you pamper yourself silly with a PSU which doesn't bother spinning the fan. :D
In all seriousness though, I agree. I'd been fine with a smaller PSU.
Buying extra does help with maintaining zero RPM -- you're absolutely right with that!
@@GamersNexus But at that high of wattage, it would also mean less efficiency at lower power draw.
@@GamersNexus Seasonic fanless?
@@squatch545 actually it wouldnt make much of a difference if its a psu thats been made well ie the 1600xi psu in the beginning of the video that had 93% rating at 200w and the max being 96%.
@@squatch545 not necessarily. a titanium PSU at a 20% load has the same efficiency as a platinum PSU at a 50% load. and at a 10% load, a titanium PSU has the same efficiency as a gold PSU at a 50% load.

GN: don't overbuy on wattage
Jayztwocents: MORE POWER!
Nearly every time I have built a system I find a good quality 650 to 750 watt PSU costs within 10-20 bucks of a similar quality 450-550 PSU. To ensure an upgrade path I would never drop below a 550 watt PSU anyway, so usually I bought something 100 to 200 watts higher for close to the same price. There was almost always a great deals on a 650- 750 watt on Amazon, Newegg, etc so overkill city in all my builds. I know I don't need that much power, but its one less thing I usually have to worry about when troubleshooting my system.
Seems pretty on time, knowing what's about to happen~
Kudos GN on being there for consumers with this timely info
The video with JonnyGuru is what brought me to this channel when I was researching PSU's a few years back. Thankful that I found GN and happy to be a Patreon!
Good stuff man, I subscribed :)
i think this applies for people who just buy a pc and aren't going to upgrade their pc for many years or oc their system. in my case i got a 850w even though all i needed was a 750w psu, mainly did it for future gpu upgrade so i wouldn't have to also buy another psu.
Omg Rtx 3000 launch today.. gamersnexus bang 💥💥💥 we are lucky to have you Steve ... Thanks much 👍
I always purchased overkill PSU's. Last week I had to purchase a smart plug to calculate the power consumption of various spots around my house. Got shocked to see that my PC (1080ti, 3600x, tons of drives, leds, etc) was consuming just 300W out of my 850W PSU.
This video comes in a very appropiate time lol.
I had an 850w PSU back when it was relatively needed & still have it today. While Wattages have gotten significantly lower and people can build for ‘cheaper’ I would still recommend people get around 600w just based on the quality of components alone.
Lower wattage PSUs tend to have lesser or not the highest quality components bc usually you get what you pay for.
If you can find a quality >600w PSU then go for it.
I’ll be keeping mine & it’ll hold me for a long time.
@@ZambonieDude When you say a quality 600w you mean a psu that has a bunch of built in protections?
Was this under load ?
Did you test under full load? Doubt it lmao
Thank you! I was wondering if the 600 watt PSU, I bought twelve years ago, because it has blue LEDs, should be replaced when I finally get into my next build. Both it, and my acrylic case, will be reused for about another year before moving all the components into something else. I may even get an AIO at that point.
Awesome and needed vídeo thanks very much
Looks like my 650w psu will be enough for a 3080 for now. Why were we all freaking out again? Awesome video.
Is it still going strong? I found that I needed at least an 850W for my 6900XT. My EVGA 850W gave out on me and so I ended up getting a 1000W Titanium from Seasonic and I am really appreciating the headroom and efficiency.
@@asplmn well, when I made this post, I didn't think there would be the crazy shortages we're having now. So I have no idea how much a 3080 will actually need it reality. The Corsair I've got is still running great though. Granted, i'm running a Asus 2070 it's definitely more than enough headroom.
I opted for a 850watt PSU when I buildt my first in 2014, I'm a happy camper with my present 3700X, AIO, 64Gb RAM four fans, 5 SSDs and a 3080 OC, seeing up to 550watts used while gaming. :)
I just want you to know that you've gamed CZcams's ad algorithm so that I'm getting a cat litter banner ad on the app. I, for one, salute you.
great info to have, thanks
I ran an AX1200 on a moderate to semi-enthusiast level and it lasted for 12 years. Just replaced it with an HX1200(Platinum). Well worth the money considering all the power outages due to storms and whatever else over the years. Powered on/off usually multiple times daily over that time. The built-in protections and quality components are well worth it.
[looks at notification bell... looks at the time] Oh whatever, computers are one third of the reasons why I've never gone to bed on time...
It's the opposite for me, I just woke up
Good to know my 650w psu would last me a few more upgrade generations before i need to start considering an upgrade. Thanks Steve, helpful as always :)
My 500 watt can power more Molex and Sata than my newer 650 watt. They have redesigned them since 2014 when I bought the 500 watt. Makes sense with M.2 becoming more prevalent on MBs and SATA SSDs becoming cheaper.
I have a 650w psu as well. I just hope it’s enough for a 3090 :|
@@Jonny-y2k probably. Most of the other parts run off different rails. If the GPU pulls 400 you have 250 for a CPU and pretty much in a gaming load that is incredibly hard to even get close to.

If you can afford a $1400 graphics card, you can afford a new power supply.
@@EmergencyChannel this
you guys should do a video covering power spikes on some of these newer video cards (3080, 6900xt) and some old cards (vega 64). it seems there are some cards spiking high enough to trigger overcurrent protection on power supplies that should be more than capable. Seems you guys tested with one massive PSU (1600w) which i'd expect would handle these spikes just fine. would have been good to see how lower capacity/quality PSUs did on these benchmarks. Power Spikes/overcurrent protection is important and ruins builds that, on paper, should be 100% fine.
Steve, would be nice for this topic to be "revisited" especially after the fairly recent video about transient spikes on the latest GPUs (CPUs?)
When I saw that some system shut down after an even brief 10ms spike, I'm concerned if the 1000W PSU for a 12700k and 12 GB 3080 will suffice.
Thanks from this old man, long time viewer.
_I'm concerned if the 1000W PSU for a 12700k and 12 GB 3080 will suffice._
For what it is worth; I'm running a 10700k (OC'ed to 5.1 all core) and a 3080 strix on a 750 watt psu with zero issues.
@@Kaymen1980 your account is very helpful! thanks
Literally just happened to me and I'm wonder in how much higher I'll have to go. Mind you I have a 750w
Even the 4090 and 13900k beast with a ROG Maximus board a couple of HDD, 128GB DDR5 7200 RAM and a 380mm AIO and the requisite case fans combined draw 890w with both the CPU and GPU running 100% (stock Clocks) concurrently. 1000w for a 12700k and 3080 is plenty unless there is overclocking / custom loops and / or some other high draw components
@@TB-up4xi not being sarcastic but how do do calculate that?
I've seen some videos saying I need to multiply my tdp by 1.5, which seems to be a lot.
Just purchased an 850w Xpg PSU.
Which I thought to be enough,
According to PCPartPicker my build is around 778watts
But with that weird 1.5 rule everything is out of wack going as far as to need a 100pw if I were to follow the guide line.
My Build is
I'm 13900k
Rtx 3080 ti
64gb Ram DDR4 3600mhz (16x4)
Xpg ssd 2tb
HDD 2tb
Do you think is enough?
I'm kind of having second thoughts about the 850w but there is no returns
5:25 - I like that you named the PSU "STEVE".
Interesting video. I'm using a 500W power supply and I already knew it was overkill, but I wanted a fully modular one and the 500W gold was cheaper than the 450W gold for some weird reason when I bought it.
Great video, thanks! I have 2 systems with the same hardware but different case/PSU, 9900k and 2080ti on both and on power meters they read idle at 82w and 480w on load, One has a EVGA 550w PSU and the other a Thermaltake 850w.

@@robertpuskaric5364 Huge difference on hardware but that could be many other things...
I'm happy with a 550 W PSU when running a RTX 4070 and Ryzen 5 5600. 250 W under load when the GPU is undervolted means I'm in the sweet spot and if one day I needs the extra performance I can stop the undervolting and still be fine with 300 W under load. I did not consider upgrading the last GPU generations because they were not energy efficient enough but this gen seems fine.
I remember having a switch on the back of PSUs for 120v and 240v. That's how I fried my very first power supply... Like most charges these days most modern PSU's automatically detect the voltage now and can run on 100-240v.
In my early days, I killed my low quality, no name power supply by flicking that switch as my system was running.
My heart stopped when it popped and immediately turned off.
have to say, that video thumbnail looks great, 5 stars ;)
I have a 750w PSU (XFX XXX black) that is 7 years old and going strong. I had to swap out the cooling fan due to noise issues but that's been it. The 750w psu was from SLI days with overclocking and such. Now that I've upgraded to the recent 65w AMD cpus and run a 1070ti; it doesn't even get past 305W at the wall under full 100% gpu/cpu load. I've also consolidated to SSD drives over the years (so no longer run 4 spinning HDD) and usb expansion cards and such have all been integrated into the motherboard. I think a 600W supply is more than enough these days. We're not going back to SLI
I have the EVGA 650 GQ 80+ gold semi-modular PS.
Spent months researching power requirements, 80+ ratings, modular vs semi vs non, what PSUs came with black cables, then saw this on sale $30 off.
Black Friday and Boxing day FTW.
Would love to see an update when the new gpus are all out. See how big Navi and the 3000 compare

Holy shit great info I did not know this was thinking at least 750w min but NOW I know better. Ty
Thanks for helping me with watt to consider
What watt, what?
So glad gamers nexus cares about us night shifters. Giving us content to get through the long night.
And something I've been wanting, to prove my point in my PSU purchase to some "smarter" friends.
For my gaming rigs, I never go below 1000W Platinum. (3700X/2080Super)
It's cold to the touch and the fan doesn't even come on.
You reviewers never talk about the heat/noise generation as part of the complete package.
Plus, due to less stress/heat, I've been able to carry them through builds.
I have about 3 1000W Platinums now. Fractal Design, Seasonic, Rosewill
This is my thought about this also. With MIG welders it's called "duty cycle" how many amps can you draw and for how long before it over heats and trips off. Pushing a small psu hard is going to make it run hot, inefficiently and have a short life. I prefer at least 25 - 30% "head space" over the expected load on any electrical devices capacity such as emergency generators, inverters, solar panels and battery banks.
This is a good point. I'm looking at building something with the new releases of CPUs/GPUs coming out and will have to take this into consideration.
i had a SST-DA1000 from silver stone.. its gone thru 4 builds over 15 years... and two weeks ago just died... it had running dual 275s 680ti 980ti. single 1080ti . and allot of overclocking . few occasions dual cpu . xD max i reached was 890 watss . but with the headroom it was pretty much in its efficiency sweetspot but with modern gpus.. i whent with 850watt and a milder cpu/mobo combo
Happy to hear that my old PSU will be able to keep the load of new Radeon GPU and AMD CPU. Now, lets wait until stock will be available.
