    I’ve been using the RMX Series RM1000x for my new PC and it’s been awesome. Install was easy since it’s fully modular so I had an easier time with cable management. The cables themselves are nice and flexible feeling high quality. There were more than enough connectors for everything I needed. It also runs great. The power supply is super quiet even under load and there’s no coil whine or anything sketchy. It’s solid reliable power and high comforting for high end components.

    Powers my build. It has no issues and its really quiet. Corsair products are reliable from my experience and it has a 10 year warranty from Corsair so that eases my mind although I hope ill never have to use it.

    Its good. Power connector for the new RTX 5000 series is nice to have. One con is that the cables wires are not braided or connected within each module. So it can be messy without Velcro ties, etc.

    Best Power Supply Unit I’ve ever bought. 1000w is perfect and even has a knob on the back to adjust fan speed RPM’s. Has so much built in protection as well which makes me feel safer with my PC. Would highly recommend!

    This PSU made my life easier. I originally had a 2060S hooked up to it and just upgraded to a 5070Ti. The swap was very easy, didn’t have to take it out.

    Great PSU! I had to replace my 2.53 version ATX unit due to power spikes causing my GPU to black out and stutter. This unit is amazing. Rock solid power

    It works pretty well. The fan is unnoticeable, and also, if there's a Cybernetics platinum version of this PSU, because the box says Cybernetics platinum

    I’ve been using Corsair products and power supplies for years. They are very reliable and this one will likely last quite a while as well. In the event that it doesn’t, Corsair has a 10 year warranty and an excellent RMA process so you can feel safe with your purchase should any issues arise (which isn’t likely given their track record). I paired this with a 9950X3D, Corsair Titan 360 iCUE Link , 96GB DDR5 6000 CL 30, and an RTX 5070, and it handles it no problem.
