Epilogue
The Corsair RM750x meets the ATX v3.1 requirements for transient response loads and achieves high overall performance. I would like to see it have lower voltage drops at 12V under transient loads, but it is still far from the respective limits. The ability to adjust the minimum fan speed through a knob located at the PSU’s front side is an interesting feature, providing more control to interested users. This feature offers increased compatibility to the PSU with the chassis that users will choose to pair it with. Another nice feature is the fan failure protection that Corsair implemented in this platform. The fan’s proper operation is crucial and can significantly affect the power supply’s operation. Therefore, it is time to see more brands implementing this protection. I added an extra 0.25 points bonus for every PSU with fan failure protection to push them to do so.
Unfortunately, the MSRP prices of the new Corsair RMx units are higher than the street prices of competing offerings, but hopefully, once the PSUs hit the market, their street prices will be notably lower. All of us want as low prices as possible, but the truth is that brands that employ many engineers to build unique platforms for them also have to pay them. It is not as easy as getting a ready platform from the factory, putting your label on it, and getting over with it. A note: the platforms that the new RMx units use have been designed and developed by Corsair’s and CWT’s engineers and are exclusive to Corsair only, meaning no other brand can use them.

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!
