After searching so long for the RM550x as you mention it in every video, I gave up and switched to Leica adapter and a pico psu. But the option was not good for me after many search and test I went for rm650 2023, a recently released and available option for a good price. It’s power consumption is similar or 1w more than the pico psu. Probably you can switch from suggesting rm550x.
I’ve heard that many people at least in germany goy scammed for a rm550x.
Parsing PDF is tricky! 😅 What library did you use to extract the values from the PDFs?
Wish I could Like this more than once. Very well explained and compiled list. Thanks!
Corsair sell a 550 RMX – its a newer version, but it's not in the spreadsheet. How does this fare?
Now we need a whats the best CPU video 😀
Hi thanks for the video. Guys what do you think about 200w gold SFX PSU. Are they efficient as pico psu ? Especially the one in the inWin B1 case, any thoughts ? Thanks
heres an interesting motherboard to test!

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.
Can anyone help clarify some things for me. Google has given me mixed answers.
1:- If I have a 500w PSU and the pc is idling with a load less than 10% ( perhaps 30w) will the PSU draw a corresponding lower current or will it just sit at 10% draw from its plug?
2:- Additionally, how do people figure out the idle wattage of a system.
3:- I’m using parts picker wattage calculator. Is it any good or is there a better one?
4:- if a machine sits at 50W most of the time and occasionally goes up to 300W but the PSU is a 750W, is the oversized PSU adding a higher running cost than a better matched PSU? (Apart from initial purchase price)
Thanks for your answers.
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.
Anything above 75% is probably fine on 20 W load, 10%. increase in efficiency would mean only 2 W less heat, or equivalent to a small spinning case fan, so the PSU fan/case thermals can become a factor too at that point. Correct me if I am wrong.
Where are the flex-atx psu, i have a Silverstone FX350-G and they said at 20% load i get 87% efficiency but i can't find any review other than official site
3:55 👏👍You are doing it right
Shame they don't have data for the Prime Gold series. I have a couple Prime Gold 650Ws.
EDIT: Actually, they do. I guess some data didn't make it into the sheet somehow?
650W variant results:
20W – 71.749%
40W – 81.354%
60W – 85.241%
80W – 87.351%
(AKA disappointingly average across the board. It still got a Platinum rating from Cybenetics though, likely because in a gaming PC application where you use closer to 100W idle and maybe 200W if not more under load, it's 89-91% efficient)
The Cooler Master MWE 400 is the newest V2 White, It's a typo on their names xD (this is the Serial Number for it from the PDF MPE4001ACABW), with the extra numbers removed. It matches the official page 1 to 1
❤
This is incredible timing, was just doing the cybernetics scan by hand a couple days ago. Great work, much appreciated
Good job, that's very helpful! 👍
Just what I needed!
This is really great. Thanks. Finally there is a way to start to narrow down a selection and filter etc based on useful and empirical data for a criteria.
Would you be interested in developing this a little further?
I dug into a few PSUs in the top 20 most efficient for the 20W, 40W, 60W, 80W range and found that some had very noisy fans. Some have fans that are quiet up to 50% load and kick in after that. Some kick in after 40% load. I guess the important data points are
– what power draw or Load % will the fan start
– what RPM and dB is that at.
The other fan RPM data points and dB values are valuable too but that is perhaps difficult to put on a table clearly. Possibly the 80% Load dB value would help to round out a picture of how noisy the PSU is across its typical use experience.
Its just a thought. I really appreciate this data as is. Thanks for the effort.
