Amazing video!! I can see a lot of effort went into it, really well done.
Also I'm a lucky owner of a Seasonic Prime Titanium 750W, I got it a year ago on the used market for 99$ (I think the person selling it did not realize what an amazing deal that was!)
And I still got warranty until 2032 😂
Hallo Wolfgang
Könntest du beim Dok. die "%" Zeichen aus den "xxW Efficiency" Spalten entfernen? So könnte die Filteransicht auch korrekt verwendet werden. bsp. "grösser als" und "kleiner als". merci
this is awesome, thank you! Thanks to you my home server is running smoothly and I got to learn a lot about the topic :) thanks again!
great effort, but honestly, if you're up to meet a price point while trying to achieve maximum efficiency, you're kinda lost. basically there are no really good solutions for that, since either PSUs from the list are very expensive or not very available to buy.
I've been thinking to build my own, kind of specialized "PicoPSU" with one or multiple highly efficient 5V switching voltage converters. PicoPSU has one huge issue IMO: for a highly efficient SSD NAS as an example, you might get away with a 60W PicoPSU but because of the power demand of multiple SSDs in a RAID array while writing, you might end up needing a 160W or bigger PicoPSU and still may be underpowered.
I examined the sheet and i think that for corsair sf 450 platinum there is a error, the classificati doesnt macht tests done by other site as anandthec i. e.
Someone already mentioned, but you could take a look at UPSs! For an even deeper rabbit hole. So far even a smallish ups draws more then my "homelab". And the old APC beast that can run gas boiler + homelab + network stuff for hours draws draws around 40w just sitting without any load...
Yeah ! I now use a single AC-12v DC conversion stage to power all my home devices, a Meanwell ADD155 which includes a UPS function using a 12v lead-acid battery. All the home network devices then run off that 12v uninterruptable supply. By only having a single AC-DC stage for everything I'm minimising my power losses.
@@AndyMcClementsThat’s so cool. I’d like to try that, have you written up your setup in more detail anywhere?
@@rileybaker8294 Thanks, no I've not done a write-up yet but maybe I should do as my whole setup is a bit unusual. The power side of it in its present form started with a lucky Ebay bargain, the Meanwell ADD-155 PSU/UPS, new for like #30 or something. I got a couple of typical small sealed lead-acid batteries used in standby applications. The ADD outputs 13.8v @9.5A + 5v@3A, which is fine for my needs as I'm prepared to compromise on compute power. Many small network devices run fine from either the 5v or 13.8v (eg. RPi, small Netgear switches, thin-client servers). I also have a couple of the Mini-box DC PSU's, for a couple of devices which need 'ATX' type power. HTH
Thanks Wolfgang. And why spend days writing scripts that can scrape the contents that will take hours to do manually? Because its fun! Great research thanks.
My UPS is using ~10W all the time .. which was a surprise.
That spreadsheet is a great resource for the low power community. Thanks for pulling it together. I've been using Corsair RM series exclusively since the mid-2010s, including an RM550x in my main 24/7 server. So disappointing that they keep getting rid of the lower power options. I have an RM450 from 2015 but now the lowest power RM is 650 watts. People building low power systems want good power supplies too.
Factors could be low sales or reliability problems resulting in returns.
Another awesome contribution to the low-power homelab community!! Thanks Wolfgang!
Thanks for your hard work making the Cybernetics data more accessible Wolfgang. Their data and your spreadsheet are indeed a precious resource. I've now ordered an RM750x for my new build. 💪
I loved this video! It's going to be very helpful when I build my first server. I love making these kinda spreadsheets and i could relate so much to you deciding to make a python script to automate something you could do much faster manually haha! Gonna bookmark the link right now
Thanks for these videos Wolfgang. I recently had to rebuild my home server. I had gift vouchers which limited where I could spend them. I made an educated guess based on your prior videos and picked up a RM750x 2021. Effectively it cost me £5 as I had a £100 voucher. I also went for a used i5-6500 system based on system database you shared on other videos. Just wanted to let you know your videos are very helpful.
Great work Wolfgang, I'm currently in the QNAP eco system, but if a CPU and motherboard because available cheap, I want to get into a DIY NAS/Server, and this info will be invaluable, saved it to a playlist for future reference. I really do enjoy your quests to find low cost and efficient server/NAS hardware.
This is incredible timing, was just doing the cybernetics scan by hand a couple days ago. Great work, much appreciated
Great video with great info! Every build I've tried to do this, and now there is a quick and easy source of info, thank you!
Damn, exactly 250k subs atm. Congrats, you deserve it. Great content as usual.
You might want to look into HDPlex power supplies as well, they are super power efficient and fit into small itx cases and have a good selection of connectors
The problem with them are the price. The 250 gan is great but it’s $150 and the 500w one is 175
I have one and the efficiency is good but it wasn’t a huge improvement. I guess the RM550X 2021 would be identical, but I have not compared it yet even though I have a spare RM550X to test… 😢
Amazing work ! I was going to spend a lot of time searching through PSU databases for low power efficiency. Your video came right in time :D
You are the MVP Wolfgang! Incredible work :)
This came at literally the perfect time for me! Awesome work dude
For my low-power home network I've ditched traditional AC-DC PSU's entirely, after factoring-in the **UPS requirement**. I use a single AC-12v DC stage which includes the UPS function (a Meanwell ADD155), then run all other devices off the 12v supply, using PicoPSU type units as needed. This means I only have one AC-DC conversion with the associated losses there.
Does your PSU have any means of configuring battery voltage ranges to accommodate for different types of battery? I am currently using a single 12v PSU that feeds directly into a cheap solar charge controller specifically because the controller can accommodate GEL, flooded and AGM battery with configurable cutoff voltages. There are also LiFePO4 batteries with built in BMS to make them useable in place of a lead battery, currently researching those as well. How long has your lead battery lived so far?
@@L1Q The ADD155 has a basic potentiometer to adjust the B+ voltage. It's intended for use with cheap SLA ~13.8v standby batteries which typically would have a life of several years, mine's been in service for ~2yrs, so far so good. My impression is that 'modern' battery technologies bring drawbacks as well as benefits, so I chose the cheap/simple option.
I have been looking for this exact list but nothing existed. A few weeks ago I needed more power for my home server which idles around 25w I looked and looked and bout the Prime titanium 750 ($163 in the US)! Thank the lord its on the top of your list HAHA! Thank you for all your hard work!
HELL YES! Thank you! I've been looking for these.
I'd like to thank you for putting together this incredibly useful comparison, I think it's the single most useful resource for homelab tinkerers.
As a new to all this coming from desktop/gaming computing, I have noticed there is practically absolutely zero products aimed for this low-power home-server niche, everything is optimized either for high-airflow racks or for less-robust home desktops, nothing in between. Putting together a low-power, low-noise, high-efficiency, high-reliability NAS/virtualization platform was definitely an adventure but absorbing a lot of info from your channel definitely helped and now I am very happy of my brand new shiny home-server.
Insane stuff Wolfang, thanks for the effort :)
Just came across your channel recently. Very good content and very useful for the average Joe. Thanks for your work
Thanks for putting all this together. Great video!!!
I love this video. I've been trying to figure out other options than the 2021 Corsair. Thank you!
Very useful work Wolfgang 🙏 Keep going!
Your efforts are much appreciated!
Very cool Wolf! thanks for the database!
Awesome video! I love the power efficiency videos
Great Info, thats what I was searching for. thank you Wolfgang and thank you to youtube for recommending ist.
After watching your video about low power servers i started building my own one. But i went the ATX power supply route and like you found the cybernetics website. After days of research i found the seasonic prime titanium psu and found one used for 80€. Glad to see that it's overall 2nd in the list.
Thanks a lot for the spreadsheet!
I think I may have found another Value King. I sorted the list by price (ascending) the Cooler Master MWE 450 achieves 78.67% efficiency at 20W and costs only 41.90€
Comparing that to the Cooler Master MWE 400 you mentioned and recommended (5th place in the chart when sorting by 20 efficiency) that has 81.12% efficiency BUT costs 1.5 times as much, using the very handy ROI calculator it would only pay off after 17 years!
So I think I'm rather going for this one 😅
Edit: nevermind, the amazon listing (which Geizhals pulled the price from) has a 6-7 month delivery time 🤦♂. It also comes with a UK power plug but that shouldn't matter in the EU as long as you have a spare PSU cable
Thanks for continues supply of awesome resources for power efficiency! This is exactly what I just needed to finish up purchasing the components for my new home server build. PS: I went with the Corsair RM750x.
Nice work!!! Keep it up Wolfgang!!!
Sehr geile Arbeit die du da gemacht hast!
Danke!
I use two fanless Seasonic PSUs. I bought one in 2017 and one back in 2014 The idle power usage of the systems is impressive. Easy to clean and not noisy!
MY GUY!!!
I am in the midst of building a custom NAS with a i3-12100 CPU on a B660 motherboard.
I just got to wondering what PSU would be good, and here you are wiyh a 2 month old video that couldn't be more relevant! Thank you!
Man, you need to get out more! But thanks for this, it's very difficult to compare these from site to site. Great work.
Thank you for this big job ! Well done.
Amazing job on the script and google sheet!
This is terrific. Thank you for sharing it!
Needed this video 2 weeks ago lol. Building a server based on that Ryzen 4650 pro based on your previous videos, thank you!
This is really GREAT work! Thanks!
Thank you for this informative video. You either take your chance by buying the cheapest PSU from facebook marketplace and use the one that comes with a prebuilt you intend to upgrade or drop big on the RM550x for the best, but now with your spreadsheet we can be more selective when "taking our chances" with the used market and filter for the best low idle PSU.
Thank you! I was struggling with choosing a PSU for my NAS and after studying this table, I bought a brand new Corsair MWE 550 for $30. Without this table, I would have spent a couple hundred bucks on the Platinum and it would still be far from ideal. Thank you!!!!
Perfect! That is just a great Video from a great Creator!
Wish I could Like this more than once. Very well explained and compiled list. Thanks!
Danke für das video. Diese Arbeit kann man nicht hoch genug einschätzen, da viele, recht viele wie ich schon seit Jahren mitlesen im unraid forum usw. (mgutt, man kennt ihn) , bin schon seit Jahren auch auf der Jagd nach ultra wenig Stromverbrauch und habs Ende 2023 aufgegeben. Mir ist es einfach zu blöd geworden. Hatte nen Lantronix mini, der war so mit 25 Watt idle ok. Dann hab ich nen OrigenAE aufgebaut, da war ein 10J ! altes seasonic titanium 460 drin und idle war das setup bei 33W. Hab dann auch geschaut und gerechnet, sogar die ~40€ gegengerechnet, die ich wohl für das alte seasonic fanless bekomm UND ja dann auch ein neues mit Garantie dafür kriege.... habs jetzt einfach drin gelassen. Weil ein neues sparsames fanless liegt schon so um die 150€, also auch 3Jahre mindestens drin. Würde sogar beim nächsten AM4 4650 pro build wieder so ein gebrauchts fanless um 40-60€ holen. ;-) Was will ich sparen, Strom oder Geld? Denk ich werd mir die Liste mal anschauen müssen um dann nochmal alles durchzurechnen. man kann es einfach nicht lassen.
Nice work Wolfgang, since i believe that you and i share similar expectations from our environment. I live in NL where electricity is also very expensive and follow your videos closely
Awesome work. You are a gentleman ad a scholar and I salute you.
Another wolfgang video, have a great day
Would be interesting to see, how they compare to pico psus though. But I know, that it is more complicated with them, since you have the efficiency of the pico psu itself and the power brick. But comparing 12V input ones to wide range input ones might be interesting.
it's not that it's complicated, it's the fact when we talk about PicoPSUs the most inefficient part is the AC-DC converter(AKA power brick).
Good job, that's very helpful! 👍
Thank you Wolfgang, I'm getting the CM MWE400. It has 6 SATA cables. I don't care for modular cables. It even has 5 years of warranty. Also, I don't mind a permanent ~700RPM spin.
Thanks mate this is exactly what I've been looking for - I currently have a random £20 PSU in my server and I monitor the power usage with a Tapo P110. It has an i5 4590T, one HDD, 3 SSDs, a TV tuner and Flightradar ADS-B dongle idling at around 27w...whilst that's pretty acceptable, I've no idea how much the system is using and how much is being "lost".
Great work! Though, the Cybernetics DB is quite lacking, especially for SFX PSUs. Last one I went with a Sharkoon, cheap and reasonable silent. Very Sad Corsair discontinued the cheaper options.
I'm surprised no-one's marketed their PSU as homelab optimised yet. The performance of cheap models like the CM MWE models show that it's not super expensive to make a PSU with good 20W efficiency, but by the time the homelab community notices the good models are always discontinued. The first manufacturer to take the cybenetics 20W efficiency score and shout about it on the box should sell really well
Nope. Mwe450 when I tested today consumed 60watts at idle for self running.
Thank you for your work !
sehr sehr gute Arbeit danke!
Der Pullover ist wild!
That hoodie looks super comfy
Du bist der Wahnsinn. Super geil!
this is hug work man thanks a lot.
So who wants to sacrifice himself for testing if the efficiency ratings for the Cooler Master MWE 400 V2 actually are the same as for V1? Anyone?
It can’t just be a random. The best case is that cybernetics does a review. Maybe if the community pooled donations or something?
I work for a large enterprise, but my home office is small and I can’t have loud and power hungry inefficient servers made for a a server room or data center heating up my office in summer and costing me a lot on my hydro bill. Definitely keep up the good work!
With the PicoPSU you basically rely on the power brick's efficiency, it only has to produce 5v and 3.3v and passes through the 12v, which delivers the bulk of the power. A survey on notebook charger efficiency would be interesting, too.
The home server I'm building this year is gonna get a RM750x handed down from my current gaming PC build. Bought it new in 2016, Corsair has always been rock solid to me and it'll probably keep ticking 10 years from now. Glad to see it has great numbers.
Where do you see the numbers for that one, since it can't be the 2018 or the 2021?
Great research for a use-case that should be far more popular imo
Another Wolfgang Video 😍
In the last builds I picked FSP HEXA 85+ PRO 350W.
P/N - PPA3505301. Warranty is 5 years, japanese caps, amazing price at 50€.
Measured with wattmeter i5-10400 machine idling at 20W in windows with monitor connected.
Its my go-to and would be curious to see where it lands in the efficiency table.
Perfect timing, I am looking for a new Power supply for my second server right now.
This is a very cool resource! The one issue it has seems to be that the figures in the spreadsheet are for 115V, not 230. This is something to be aware of, as the numbers can vary wildly between those two voltages. It would be great to have filters for 20-80W at 230V as well.
I'm having trouble matching the numbers in the sheet vs the published ones. The numbers in the sheet are much higher vs the published ones in the RM750x I looked up.
Cybernetics' older reports only had 115V measurements
Hey Wolfgang! Did you spot anything interesting that was announced or released at CES for homlab/NAS stuff?
I saw the minisforum MS-01 and the AR900i. Both are totally not for low budget and not very NAS friendly but those are the only things I could spot on CZcams.
Great article and realistic - actually use case of PSU, not the fetish focus on look it's platinum with loads of plus signs when that's based upon best case near on peak load, it's the scale across power load you really need.
Great work!
great work, thank you so much
Nice video! Hope you can do something similar for CPUs
is there a similar sheet for motherboards (6th/7th gen intel) my old atx gaming one i use pulls too much power on idle
There's this: docs.google.com/spreadsheets/d/1LHvT2fRp7I6Hf18LcSzsNnjp10VI-odvwZpQZKv_NCI
Great work, thank you
Do you have the efficiency for Pico PSU's @ 20W for a compassion?
*Regarding the Cooler Master MWE PSUs:*
1. *Model Variations:* Most (if not all) of the MWE PSUs listed are the V2 model. This is not explicitly stated, as the 'V2' suffix is not officially part of the model name. The V1 and V2 models differ in a few ways:
- V1 models are rated 80+ Bronze, V2 models 80+ White.
- The V1 and V2 models have different load ratings and sticker designs on the unit itself.
2. *Availability and Pricing:* Unfortunately, these MWE models have spotty availability, causing their prices to fluctuate. Here in west EU, they should be about €40-55,- depending on the model.
3. *Power Connectors:* The number of PCIe power connectors varies by model:
- The 400W model has one.
- The 550-600W models have two.
- The 650W model has four.
There are more connectivity differences, so don't forget to check.
4. *Value for Money:* Some of the higher wattage models are actually cheaper right now, so don't rule them out; they could offer better resale or repurpose value in the future.
5. *Efficiency Rating:* Cooler Master might have given them an 80+ White label, but most of these PSUs are rated as silver efficiency by Cybenetics.
I hope this was helpful, because I think the MWE White V2 lineup actually offers the best bang for the buck right now.
Spotty availability?
Sold out everywhere!
I found one Cooler Master MWE 400 !
Wow… Of course CM V550 v2 sold out on Amazon already. Good work Wolfgang 😊
Any spreadsheet for picopsu's master power supply?
Some 12v power supplies are terrible at low power efficiency as well.
Just what I needed!
Thanks. How powerefficient is that Ryzen Mobile R7 5800u ? Thinking about the new Aoostar 6 bay to replace my old selfmade NAS with the R5 3600.
Any chance you'd be willing to share the python used to automate gathering the data? It'd be great to see what approaches you used!
I am also interested in the python script. Would love to get other info from the cybernetic doc, such as fan noise
Also Also interested in the python script
Thanks You, excelent and useful job
Kurze Frage an die Expertenrunde hier wegen dem Corsair RM550x, sind nur die Modelle mit der Modellnummer RPS0121 die Effizientesten? Frage, weil es überall welche gibt, nur nicht mit dieser Modellnummer. Danke :)
This is gold! ❤
is there a way we can try stagger the drives spinning up better to reduce the max load a little bit? If anything, so we can buy cheaper PSUs?
Hey Wolfgang, thank you for this awesome resource. Upon reviewing some of the results from the spreadsheet, it appears that your script indiscriminately mixes 115V and 230V performance. I think this happens because not all results have both a 115V and a 230V section. Is it possible to serparate these values out in the spreadsheet?
After a bit of research and seeing what I could get my hands on. I ended up getting a RM750x shift from Amazon Warehouse. Super pleased it came in 6th 👍
"i plan to keep the doc updated"
MY BOY!!!
Woke up to this 👀🎉
I really don't need kr care about PSU because I use Synology and Beelink mini PC, but I watched it anyway.
Respect for gathering all that data and converting it into useful information 👍
Thank you for this.
О, ДА-аааа!!! Спасибо большое за отличный инструмент в выборе энергоэффективного блока питания!!!!
A week ago, when this video released: "Bah, I won't build anything in years, I don't need this video."
Yesterday my power supply blew up due to a faulty usb card reader, so thanks for the good timing I guess :D
Now we need a whats the best CPU video :D
Lovely jubbly. Worth using your affiliate links 👍❤
Kindest regards, friends and neighbours.
My HS idles at 12w and was using Seasonic Titanium 750w but after testing at idle mear 2% load swapped it out as it effciency was 11%!!!!!
While my cheaper Corsair vs450 was 55% effiencient
I just realised I got one of these MWE coolermaster PSUs haha.. excellent - time to direct it to a home server rig
how good it is?
