Box & Bundle
The box has a photo of the PSU on its front side and the corresponding Cybenetics ratings for efficiency and noise. If you want more data about the PSU’s technical specs, look at the back of the box.
Product Photos
The chassis has a distinct look, with the uniquely shaped perforations that Corsair used for the fan and exhaust grilles. Moreover, the PSU has standard dimensions, allowing for a 140mm fan to offer the desired airflow at low enough RPMs for reduced noise output. On the front side, you will find the power switch, the AC receptacle, and the fan speed control knob. Around the back, the modular board has ten sockets, one 12V-2×6 type. Corsair didn’t use 2x 8-pin sockets in these PSUs for the high-power PCIe connector but preferred a native one.

All cables are embossed, and the PSU has two EPS and three PCIe 6+2 pin connectors, all on dedicated cables, which is the correct/best thing to do. There is also a high-power PCIe connector, set at 600W max power, which is overkill for a 750W PSU. Normally, it should be set at 300W. There are enough cables and connectors to allow the PSU to deliver its full power effortlessly, and all cables are long enough to avoid compatibility issues. I only disagree with the short distances between the peripheral connectors.
I have been using MSI MAG A650GL PSU for the past year, there are no problems in video rendering, and in DAW usage. But when playing games which needs high GPU usage like Black Myth: wukong, when there is a power flactuation my PC restarts not always but occasionally. I’m using the 3060TI GPU, and its fine in normal games. Does this have to do anything with my psu holdup time, will this psu likely save me?
I forgot to mention I am using a 1.2kva UPS. Thank you
Hi, I just bought this psu unfortunetly I’m getting 11.8v on 12v rail by motherboard sensor and pcie gpu sensor and it lowers when in load, gpu only draw 30 watt from pcie so this is unexpected 8pin connector from gpu sensor stays around 11.9volt, is this a expected behaviour? My 10 years old bronze psu could give 12v consistently on motherboard sensor + pcie gpu sensor but 8 pin sensor was sacking to 11.7 on load. Should I return this psu I tryed my old gpu too its sensors also report low pcie voltage.
Do not trust what the mainboard’s sensors report, because they are entirely out of space (inaccurate) in most mainboards. Even a 5$ multimeter is way more accurate.
Thanks for the reply. What confuses me is how the graphics card can get normal voltage from the 8-pin connector, while the PCIe voltage from the 24-pin connector might be lower. After all, it’s the same 12V rail, right so sensor is likely the cultprit? I returned it because it was making a high-frequency sound. That’s why I didn’t try checking with a multimeter, but even if the sensors aren’t calibrated, the PCIe voltage dropping from 11.8V to 11.5V under only 30w load still raises doubts about this particular unit for me.
I am quite disappointed with the V12 of this power supply. Processor at 95w, graphics at 110w, and V12 at 11,712. What will happen when I insert a 250w graphics card? My previous 550w superflower never read below 12.
Hi Aris,
I really enjoy your content, though I rarely buy a PSU and try to keep it that way. I’m assembling a system that will consume 475w at peak CPU and GPU load (though that will only happen during a synthetic benchmark). For headroom and future-proofing, I’m planning to buy a 750w PSU. What would you recommend between an XPG Core Reactor II, Thermaltake GF3, and Corsair RMx? Is the Corsair the best choice for an Nvidia GPU given the included 12v-2×6 cable? I’m given to understand that the 6+2 to 12v-2×6 adapters are, when installed correctly, potentially better than a single 12vhpwr cable. It also seems that the Corsair is most reliable, based on consumer reviews. The XPG and Thermaltake are both 33% cheaper than the Corsair, so you could convince me to save the money but only if you felt the others could be equally reliable.
Hi! I would go for the RM750x (ATX v3.1). In general, the RMx line is one of the best out there. TT, I don’t trust it so much because I cannot know from whom it is made anymore. The XPG is pretty good, but I still prefer the Corsair unit.
Thank you!
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.
Hello, how did it go with the new power supply? Did everything work properly?
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!
