Average Noise
The PSU’s average noise output is low at both voltage inputs.
Fan Noise & Speed Maps @ 28-32 °C – 115V
The semi-passive operation doesn’t last long if you push the minor rails hard. Corsair also sets the minor rails’ max combined power at 150W, while most modern platforms keep it at 100W. The high combined power on the minor rails is a disadvantage in these tests. At up to 460W at 12V, the PSU’s noise is kept below 20 dBA. The PSU’s noise doesn’t exceed 30 dBA in these tests.
Fan Noise & Speed Maps @ 28-32 °C – 230V
The 230V fan noise profile differs slightly from the 115V one. The semi-passive mode lasts about the same, and the below 20 dBA operation is up to 505W, at 12V.

Hi Aris,
I got this PSU after comparing many of the models you reviewed, manly for it’s low noise output and overall good performance. However my unit has extremely loud coil whine. I got it replaced under warranty, but the new one has the same issue. I assume this is happening because the PSU is almost exclusively operating in Burst Mode, since my system is drawing very little power (Zen 5 CPU, no GPU). Installing a GPU might resolve this, but that’s not something I can do right now. What would you suggest to resolve this issue? Get a lower rated Unit? A different model? Thanks for all these great reviews and work over at Cybenetics!
hm coil whine is a huge issue and also has to do with the rest system components. A lower rating PSU might help yes, but still it is mostly a trial-and-error procedure.
Tanks for taking the time to reply! I will give the new RM650e a shot, since it also performed well and has low noise output. It’s a shame since I got a great deal for the RM750x at 99,99€ on Black Friday, but it is what it is.
I just order this, but i cant get the Seasonic out of my head, is it worth another 20 usd over this one? Im very casual gamer and will be going in a 13600+4070 combo hopefully
Nice review, i buy this PSU(130 euro) and is amazing.
Hi, on page 8 “protections” it says 1046w for the OPP, but how is that 123% of 750w ? It would be 123% for a 850W unit, but for a 750W unit 1046W is 139.5%. If the OPP is set at 123%, then shouldn’t that be 922.5W ?
yeah the 850W unit’s table was there. Fixed now, thanks!
Thank you for the detailed review and your time spent for testing the units.
I just bought this unit on Amazon during BlackFriday deal because of good result in your test.
Aris did PCCooler YS1200 basically same PCB parts & design of Seasonic GX/PX-1200 ?
U mean the “Same Platform” thing?
Don’t remember sorry. please check Cybenetics if there is parts description for both units there.
Thank you for all these PSUs reviews !
you are welcome!
