Bro I’m running a 308012gb i7 12700k 32gb ram 2tb ssd is 1000 w psu good enough with over clocking and everything .. thanks love your channel.
This is cool.
Steve you could have in this video as a guest Aris Mpitziopoulos too. He's not affiliated with a company and PSUs are his field of expertise.
Jeez, this is really interesting.... just a thought, if you could get Jonny and Patrick in front of a white-board (or maybe a black-board would even be better), for a few hours, and just feed them coffee after coffee, with some editing and "host" snippets that could easily generate an amazingly interesting deep-dive series, for which this series could effectively be just a preview. I'm sure /dozens/ of viewers would eagerly tune in to watch such a show!
I keep saying this but we're all afraid to poke around in PSUs as everyone says we could die, apparently in earnest. There just isn't a ton of easily digestible information out there. Watching Jonny simply rattle off the major glossary terms is actually a huge help. Next stop: Wikipedia, obv. -- armed with a this jargon-lexicon, we'll all surely be better equipped to start understanding what's going on in these (often literal) black boxes.
I really like Patrick's enthusiasm for learning more about the different components. You can hear it in his voice!
Always great to learn from experts in these meetings!
This, and I feel like he did a great job getting Jon to focus more on the basics and visuals for the audience, which I really appreciate.
@@GamersNexus Cheers for this video!
For a LONG time I've been looking for a solution to create an efficient, adjustable regulator for a transformer I have that puts out 32v @ 60 amps. Hearing about "mosfet rectifiers" (which I scoffed at, at first) sent me down the rabbit hole into synchronous rectification. I think I just found the answer to a question that's been plaguing me for over a decade!
@@GamersNexus Yes. but Patrick need to empty the cup before you pour something in. you know your terms but you dont know what it means. the 2 primary caps cannot be combined into 1 as there is +, - and Gnd in this PSU. A Bridge rectifier does not flip negative wave forms to positive as it filters out negatives only (on one side) and capacitor charge makes up for the loss 0V. this also goes with the other side where it filters out positive wave forms and blah blah blah
I'm a pc gamer and hobbyist ee guy and I learned alot by taking them apart, reverse engineer with a schematic with values then run the math for each section. smps are complicated beasts. I'm no master. diode gone wild does alot of smps re videos. very good source if you wanna learn more and have a few minutes a day. the guy is a genius. he reverse engineered an xbox360 console supply once that someone sent in and the guy had no idea what an Xbox was and he's in his 30s. haha
I legit felt like I was back in my electronics 101 class haha. Gotta love teardowns and "how it works" deep down in my engineering soul!!
I enjoy these videos as well. This stuff brings back memories for me.
Same, since I came from a technical school and had 2 years worth of electronics class but it still feels good knowing this kind of info to a certain degree even if I opted to go for Electrical instead of electronics.
still crazy how we can use wires n shit for sound and picture like the amount of research is unreal

I actually deal with EMI noise in my field of work. In Controlled Environment Agriculture (indoor gardening) lighting is obviously important. 1000 watt electronic ballasts were the mainstay in the industry for a long time. And as it got more popular and Amazon brands popped up, there was also a HUGE uptick in EMI issues. Usually Cable service would get terrible for anyone in the area, and it came down to cheap lighting ballasts just BROADCASTING massive interference.
Usually this was discovered by someone else and they would call their Cable company and they'd send someone out who would at some point end up at the address, because the interference was so great, that their meters led them directly there.
Crazy important part of an electronic device.
I commented on this elsewhere but do you know if this could be what causes dimmer switches to have problems? I've heard of it with some EVSEs ("car chargers")
Ah yes, 'indoor gardening.' Especially popular at 4:20.
@@aapje for sure that's one aspect of it, and the driver of crap gear. "Save a buck and get visited by Comcast" instead of 4:20 though you'd be better off with "8:00 and 8:00" if we play the grow humor game.
@@chunkychuck it could, depends on the type of dimmer. Lots are variable resistors, but others are just digital counters that DO rely on signaling.
that wasn't a bug, it was a feature. bait hook in the fish barrel as it were.
I think this is going to be one of the most useful videos, i'm tired of people thinking efficiency rating = quality
@squigga yeah its why the ltt psu tier list should be recommended more often imo makes it 10x easier for new pc builders
That's not going to stop at all, people have been told for over a couple decades, that the +80 system rating is the best gauge of psu quality.
@@AwankO At least it's something right? To reach titanium, you probably need better components than bronze.
That's why I'm grateful for the whole Gigabyte exploding PSUs fiasco. I can always point to them and say "look, they're rated 80+ Gold and still exploded". I also agree that it's very confusing for people new to DIY PCs (then again, what isn't? Every single component is a rabbit hole), that's why independent, in-depth review channels are so important. You don't have to understand what they say, but when people like Steve say "This is fine" at the end of the video, you know you're on the safe side.
@@deher9110 they have a power supply tier list?
last vid left me wanting more Johnny, and now we get more with Patrick too? Hell yeah
I miss JonnyGuru's website. I know that text based reviews don't get much traffic in this clickbait driven youtube landscape, but I grew up preferring text based reviews since I could read it at my pace and they could cram in a lot of info that doesn't work in a video. I learned A LOT from JonnyGuru and similar pages.
You have no idea how much I miss his site.
We all miss it. It’s sad.
I also prefer text articles for efficiency reason. I feel sad that GN is no longer updating their website.
Johnny got sold…
You guys should do more general electrical engineering stuff with experts, I think it's foundational material that a lot of PC enthusiasts lack and the rest tend to take for granted.
Steve, this should be a series. Interview the ultimate knowledge source in every field. Love your content, please post 4x a day.
Supported
Love the content.
But don't post 4x a day
Post only as much as you can sustain long term.
I think listening to Patric get excited was the best part of this. When you love what you do, it shows and is fun to watch.
Always love watching Jonny Guru content, could watch hours of this content as it's really interesting on how PSUs are built and work 🙂
Back to you Steve
As a computer engineer who didn't absorb nearly enough of my EE courses, this was a really great video for getting into some of the thought behind PSU design decisions. I really appreciate your and Jon's work on this and look forward to more PSU content.
Random Signals and Noise says Hi... More seriously, I don't think modern power supply design was covered at all in my EE courses.
@@arthurmoore9488 Switching power supplies generally aren't covered much, unless it's specific for a graduate degree in Electrics/Electronics Engineering (at which point, you'll passively learn about most of the component circuits and get to combine them all at the end). Pretty difficult to teach someone how to regulate a fast switching MOSFET signal when they don't even understand what a MOSFET signal is.
Fun fact also about power supplies I don't think was mentioned, the MOSFETs used for switching often have drain connected to the body, so in some cases the heatsink can be live, once blew up a PSU when a screw fell in right between two heatsinks.
Also, regarding the MOSFET full bridge rectifier, really handy for high current/low voltage applications. I made my own for 12v/200A, diode based rectifiers commonly have a 0.6v drop across them, which is 120 watts of loss before resistance is considered, so I gained a solid 5-10% efficiency bonus going with an active solution.
loved watching a hardware engineer be honest and direct, great video, thank you for making it.
Nice to see inside my own PSU being the RM850x. Nice video!
I wish Corsair clearly advertised the differences between models like the rm850 & rm850x . Had I realized, I would 100% have gone with the rm850x for the maglev fan & higher quality caps over the rm850 I put in my latest build.
I would imagine you wouldn’t see the difference in reliability or performance. Maybe the fan would be noisier or more whine from the psu under load? I wouldn’t worry personally.
John is a wonderful teacher and Patrick's enthusiasm makes it all the more engaging.
Please do more of these expert breakdowns if you can.
Awesome video. So informative. Love when you guys go out and clear up misconceptions with the experts!
Love how enthusiastic Stone was getting with each explanation. Its fun to see folks get excited about stuff majority of folks dont think to realize.
Jonny - "Your bridge rectifier is not always your bridge diode, you also have a thing called a mosfet bridge on some of the higher end products"
Stone - "Oooohhhh!"
Good stuff GN
Also very interesting from the other end of the spectrum - as someone with knowledge of how these electronic circuits work, it's fun to see things I'd take as obvious being learned in real time.
3:10 470v volts, yeah...;
4:12 it is regulated;
4:30 wrong mosfets shown;
4:45 ...output caps... *points at standby smps*;
5:10 ...5volt standby... *points at PFC inductor*;
13:02 a gate drive transformer.
I understand that it could be a bunch of silly mistakes on camera, but at least, fix it in b-rolls and captions. Do not release bad quality info.
Thanks!
Thanks, that LLC tank caption had me confused. After reading up a bit on LLC converters, it didn't make sense that the LLC tank would be so small and off to the side. It should be integrated with the isolation transformer, if I understood correctly, right?
yeah the bridge rectifier does not produce 420-470 volts DC, and the values written on the caps are absolute maximum ratings, usually nearly twice as much as they are actually handling. They will be 470v rated to handle the max input voltage of 240v, most likely.
@@CoverMechanic it's still at the same voltage as the wall after the rectifier, they said as much in the video. It goes to ~400v in the pfc stage of the power supply
not to mention they never even talked about power factor correction
Very informative! Would love to see more segments like this with the high level schematics also.
Currently taking an electronics course in the mechanic program I'm doing and it's cool to see things I've learned about in this video. I actually understood most of what Jonny talked about! Neat!
Is there a video that explains this video?
Lmao id need a video that explains that video
This was absolutely fantastic. Extremely informative and detailed. Thank you. Would love more content like this on other components; especially motherboards if this can be arranged? :) Huge thank you to Jon of Corsair for his time on this one.
Really enjoy these videos w/ Jon. Dude knows a ton and you can tell has a passion for it, makes it that much more interesting.
This makes me want a Corsair PSU. Other psu manufacturers probably have their own Jonnys, but *knowing* Corsair has Jonny makes me want to buy a Corsair PSU. I feel like if I buy a Corsair product, it has Jonny's blessing and should be capable and of good quality.
The only PSU I've had fail recently was a Corsair PSU that would not run at higher than 50% of it's rated power
@@dennydravis8758 What model?
@@ej_tech your mother 250w
Lol, read my comment above. Search the internet for Corsair AX1200i PSU shutdowns, designed by Jonny freaking Guru, there are a TON of users reporting malfunction. I have 2 units and they've given me problems and more problems, and they were very expensive at the time. Wouldn't be surprised if other Corsair models were having similar problems, their current reading and protection malfunction is a complete disaster. Had so many problems that will never buy a Corsair PSU again, will go for Seasonic or EVGA instead.
I've head a cheapo Corsair PSU in a secondary PC (450w or something) and it was horrible. A lot of coil noise and random shutdowns for no reason on a reasonable configuration, i5-6500 + GTX 1650, 2x8GB, 1 SSD. There's no way those components topped that PSU. But for $30-40, no brand can make a decent PSU.
Had two AX750, Seasonic manufactured, very good and zero issues. Now running a. Seasonic Prime 750W Titanium bought on sale. Very cool and quiet.
Loved the first, I really appreciate this kind of videos and seeing the master, Jonny Guru, in good health makes me happy.
Here's a story about my Corsair Hx1200i, one morning I started my pc and heard a bang from the case and a burned smell came. The pc would not boot anymore and before that I've had a lot of problem with starting or stopping this pc, for example I would need to press the power switch a few time to start or the reset wouldn't work or it wouldn't shut down properly and I would need to use the switch at the back of the PSU. I've sent it for RMA and they sent me the same model but refurbished, same problem came back in 3 days, pc wouldn't boot anymore, something tripped the security. So I thought my motherboard was bad and I made a new build, same problem happened within 1 day so I bought a Seasonic 650 watt gold for my old build and Seasonic 1000 watt platinum for my new build, problem is fixed ever since. Corsair refused to refund/store credit my 400$ refurbished PSU they only wanted to RMA it for a second time which I refused since I needed to pay the shipping again for a piece of crap useless PSU that would or wouldn't work. Don't buy corsair PSU, get Seasonic or EVGA.
You're really extreme in this comment. Maybe re read and also think about that this probably happens with any brand at some point.
I could make a big picture of you and post why I think this is wrong of you, and you wouldn't like it because... It's often just a part of you. Pointing out mistakes by others helps, but completely judging over it by one negative situation is usually wrong
@@heni63 Yeah I know, funny thing is that most of the parts in my pc's and peripherals are corsair, just not the PSU. Too many bad personal experience with Corsair PSU's and a load of similar testimonies from other corsair PSU users on the forums.
were you using the right cables?
@@Zeno- Yes,, the one that came with the PSU itself, no custom cables.
Absolutely great to see Jonny Guru explaining all this stuff. Back in the day I was always reading his site for the great psu reviews. Loved the exploding ones. :)
I love this PSU class with Prof Johnny Guru. really educational.
I could watch these kind of videos for hours and hours. So much information cramped into one video.
Pretty cool bit of history with the Brush Electric Company. Thanks Steve, Patrick, & Jonny for the great PSU info 👍
instant thumbs up, I could listen to Jon for hours talking about PSU's, would love to learn more about mosfet bridge design
Great that Stone is getting some lessons from the Master Guru! I hope you guys at GN know how much we appreciate what you do, and the lengths you all go through to bring us this knowledge. You are the standard that everyone should aspire to achieve. o7
Excellent video I love watching Patrick and Jon chat. Keep up the great work!
These types of videos cut through the hype and educate the consumer. This one gets an A+. Thanks, -hg
This content is great! GN, if you're looking for feedback, personally this is the type of stuff that falls outside typical review/news content for the channel but I absolutely love it. Keep it up!
such a great video, I love this format! the world of electronics is still way too complicated for me but this is a good presentation that makes the info approachable for an average person like me
I really love to watch a professional man very prepared in his work. If only we had more of this people.
These videos have made me a lot more confident in the RM750X that powers my build, nice to see Jonny again. Thanks GN
This was a fun throwback, and got to learn some new things. Appreciate the deep dive.
Nice insight into what I once considered the "forbidden black box that brings life to my PC but death to me if I open it."
That description got me laughing. Pretty accurate and creative.
Thanks, Steve. And the whole GN Team for top quality facts and informations
I have learned so much more of this then i can remember from my Electronics classes
Great video for an electronics hobbyist interested in PSUs. I've been looking for a deep dive series on pc PSUs - something that would take the time to go through the schematic step-by-step and show what each part is doing, with proper explanations and scope readings. This is not yet that deep, but you certainly seem to be going for increasingly more technical content - I like that :)
Some motherboards now use the 5v standby to power RGB's when the system is off. But this will be disabled if you use the "ErP Ready" option in your bios since it considers that a waste of power.
First class power supply discussion… I commend you on an interview that discusses these inner workings. Not a lot of people can actually discuss this in an intelligent informed manner. Very much appreciated… love my coasters!
Jonny's a GOAT, I always rely on his PSU reviews back in the days.
Love Jonny Guru content!
Love this type of content! Thanks GN!
This was a fantastic video, great work team!
Thank you guys. Very informative. Appreciated from the UK
Thank you so much for this video. I feel like you heard my request. I am so grateful.
This was such a cool video. I have no idea how it works but it's nice to hear a pro and how this will trickle to better GM in the future.
Oh this is brilliant. Thanks so much to everyone for asking & answering these questions, even the very basic ones ;)
Every time Patrick touches the bulk caps my heart does stop tho ⚡️💔⚡️
I really like to be in conversations just to listen people who know things.. And the fact that they share, learn on the way... It's so human in a world like nowadays where it seems so many times you must be an all around expert since the start
I feel like this meeting for Patrick is akin to us meeting GN in terms of excitement and learning value.
As an electrical engineer I was able to follow along but to make this more approachable to lay people briefly explaining what the components that your listing would be helpful. Perhaps diagrams?
Need more of this, these are great!
What a resource John is for his specialization. I hope one day he’ll consider streaming a walk through of power supplies and what as consumers we need to do to help improve the overall design and implementation of new technologies.
Or if it’s even possible to get an enthusiast grade psu.
If that's what you want, might just be worth reading one of his reviews from his site back before he started with Corsair. Power supply technology has moved on of course but not to the level of CPUs, GPUs, and storage.
Love the guest engineer videos. Keep ‘em comin. Thanks.
This aged well
It was nice that Patrick was asking questions in a way so people not familiar with PSU topology and engineering can understand.
I'm sure some of the questions he asked, he already knew the answer.
The many reasons why I love Corsair and CWT for their power supplies. The support, the user-friendly attitude and the presence of JonnyGuru.
This is super interesting to know. Really cool variety of content guys, usually I'm more attentive to GPU and Processors, but now that I'm looking to buy a new motherboard and PSU, really glad I can resort to you guys to check what should I buy.
I didn't really know anything discussed in this video, but now I'm interested in learning
this is just so informative, great video!
Jonny Guru is the PowerMan! really liked his 2 Part interview.
I love the concept of the vid. I still don't know what is better or worse nor how I as a consumer can identify. Patrick Stone, It's on you to tell us! Jonny Guru is a Guru of anecdotal stories and not giving away the family secrets....
Finally something about the in depth components of a power supply
I have the RM850x and love it. I really like how the PSU fan never or rarely turns on for my my 5600x/3070. I've checked the case filter for the PSU and it's never dirty.
Thrilled to have mine and experience that too on a close setup 5600/6700XT with PBO & CPB off in the bios for the cpu, underclocked and undervolted for the gpu. average ~150W total system ( minus screen ) for 100+ fps maxed out1080p or 60fps maxed out 1440p or even 30fps 4K. ( No RT, all native no upscaling ). Enough for my mmo/rpg/adventure games like W3 NG update , RDR2 , CP77 , FFXIV etc...
I just gotta say that Steve and the fine people at Gamers Nexus are awesome! With content and their shop. I ordered some stuff from them and they emailed me back asking if the address I put was correct (it was). I can’t imagine anyone else doing that. So thanks GN for the great content, products, and service. Gold standard.
Whoa, seeing the legend, who helped shape so many of my PSU purchases, was very cool.
Great show and guest
His reviews made me pick the PSU i picked like 15 (?) years ago. Legend!
Thank you for the thorough video
Great guidance, thanks
Hey GN, thanks for the high quality content as always. There are a few inconsistencies in Jonny's explanation that I'd like to point out though:
5:14 - This is definetly not the 5VSB supply. As Stone later points out correctly this is the active PFC inductor.
13:10 - The placement of this part almost certainly disqualifies it as the LLC series inductor. The LLC series inductor should be very close to the primary of the main transformer. My best guess would be that the LLC series resonant inductor is the one to the top right of the main transformer and that the part pointed out here is the transformer for the 5VSB flyback supply.
22:20 - Yes, there is a small voltage drop in rectification. However the rectifier output voltage will still be higher than 120V, since 120V refers to the RMS mains voltage. However when rectifying the mains voltage and storing it in a capacitor it will charge up to the peak mains voltage which is sqrt(2) * 120V.
Another few comments from my side:
15:00 - Actively clamped topologies are usually not more efficient because the waveform is more compressed. Rather the spikes are effectively fed back into the main bus capacitors instead of being dissipated in passive clamping solutions like snubbers. Importantly it can also extend the usable power limit of the forward converter since demagnetization of the transformer core happens more quickly.
23:10 - Another interesting and important design aspect of bus capacitance can be impedance. Using a single, large capacitor versus multiple smaller capacitors in parallel will have a significant impact on the effective bus impedance over frequency. Depending on the exact design of the power supply this can make a huge difference, especially with respect to (conducted) EMI emissions.
It's nice to see an engineer/expert talk about his field that is not dumbed down for marketing purpouses.
Now I'm even more pleased on having a Corsair PSU!
thanks Steve!
In terms of safety regulation - "they're doing it for a reason, they're not doing it just to waste our time."
That doesn't necessarily mean it's a good reason. You might be surprised how often lobbyists are involved.
The reasons explained are good ones.
Just a little critique, when throwing acronyms around it is nice to have a moment to focus on what the acronym stands for with emphasis on what each part of the acronym means. Maybe even a pop-up on the screen. I really enjoyed the video, love these educational bits.
I have a 10yr old PSU running an X570 board, an R7 2700, m.2. drives, 32 gig of ram, rgb all sorts, and a 3070ftw3 running from it... Have I taken leave of my senses you may ask? not quite.
Although it is 10 years old, it is a modular seasonic 850w that had never been used and been in storage for its first 8 years when I bought it from the seller, only downside was the cables had long since been misplaced. So she let me have the PSU for postage, I gave her a tenner extra, didn't feel right.
I then wrote to seasonic, and they very kindly sent me an entirely new set including postage for £15 quid. Exceptionally good customer service! So I got a brand new seasons M12 II EVO modular 850w for £30 all in. Been golden so far.
Good vid, lots of juicy info as I will upgrade my PSU eventually to a better class as the only downside is it is Bronze rated. I wish PSU manufacturers would made the ENTIRE psu modular in some way, the chassis and pinout for the cabling doesn't have to change, just the internals. Would save a hell of a lot of E-waste by doing such.
The same should be of motherboards, modular should mean modular, imagine if there was some basic standardization of the motherboards like there used to be in the old socket 7 and prior days when any maker of chip would fit your board? Cant we have that back?? can we not have modular chipsets too??? Must we produce masses of crap destined for landfill soon after???
I mean we sent a man to the fucking moon 60 years ago, can the richest most advanced corporations on earth not build a PC capable of not being thrown away every 5 minutes?
Bit of a divergence from where I started but just thinking aloud.
It wasn't 60 years ago someone went to the Moon. It was only 53 years ago this July. If it was 60 years ago then I wouldn't have seen it. I hate modular PSUs. Connectors are resistance.
These videos are incredible, I'm too dumb to make any meaningful sense of it, but I hope you guys can take it back with you and use it in your PSU testing to make recommendations going forward :)
Love a good optocoupler! Hoping you guys are going to build out some reviews and charts to help us consumers better understand what we're getting for the money, especially when comparing higher end gear with a premium. I'm sure we've all wondered at some time or another if the most expensive truly is the best.
Thanks, the information I got at 11:10 about the hard switching just solved my issue. I have a 3090ti and my new 1000w Gigabyte PSU was making a really annoying noise. I'd have never figured it out if I didn't find this video - I changed to a LLC PSU and the noise has gone. I went for the 1200w BeQuiet 11 Straight Power. Thanks again!!
Great video. I always like this type of video.
Stone is so excited! Love to see that
We absolutely need more videos like these. A diluted lecture with industry veterans.
Man this guy is a nerd. Awesome video, loving all the details, I would definitely love to see this level of depth in other topics as well, the passion a true nerd has for their area of knowledge is awesome!
Super cool stuff to learn about ! ! !
I miss his site ... #1 place to go for finding a new good psu :)
very informal thanks that was really good
i love how into power supplies Stone is. top tier content.
Very fascinating video! awesome 😀
Nice education on Power Supplies, I like the kind of content you can actually learn something from. Props to Patrick for maintaining the position of his mask. The lower strap was hung up on your beard, pulling it down. Position your mask where you want it and snap the bottom straps into your beard to lock it in place.
So much information coming out of that guys mouth. He left me in the dust.
Jonny senpai and Patrick kohai 😋
Great collaboration to now more about the insides of PSUs.
It would be great in the future to have something similar but with a motherboard manufacturer.
Love the video. Thanks.
Really like my two Rm850x (2020 type). CWT and Corsair really did a good job!
