Corsair finally released the update version of its highly popular RMx line, which updates the models to meet the ATX v3.1 specification requirements. In today’s review I will look at the strongest member of the line, with 1000W max power.
The Corsair RM1000x ATX v3.1 will be included in my best ATX v3.x & PCIe 5.x PSU picks article.
The Corsair RMx line received an update to meet the ATX v3.1 requirements, which require, among others, a PSU to withstand 200% of its max power for short periods. Another unique feature of this new models is the fan speed control knob, through which you can adjust the fan’s speed at light loads, from zero RPM up to full speed. For instance, when you select a 500-600 RPM fan speed at light loads, this will be the starting point and increase once the PSU’s thermal load increases. So, instead of providing a switch to select or deselect the fan’s semi-passive mode, Corsair provided the option to choose the fan’s starting speed.
In today’s review, I will evaluate the strongest member of the RMx ATX v3.1 line, which has a maximum power of 1000W. The other two line members have a maximum power of 850W and 750W.

I’m looking into getting one of these.
But they have also downgraded the fan which is dissappointing, the previous version of the RM1000x had a magnetic levitation fan (NR140ML). Given that both versions are currently available (with the older coming in cheaper) – I am wondering if the prior version is a better purchase
I would buy the new one. The ML fan was a bit noisy with the specific fan speed profile.
I bought one of these. It made a small amount of coil whine when I tested it in my old PC, but only when idling in windows (starting any app up made the noise go away completely). However on my main PC it makes no noise whatsoever, phew! I like the fan control, I have it turned to it’s lowest setting where it is still inaudible but at least this removes the heat rather than letting it radiate in to my PC case.
