    Not many bad things to say, a solid PSU for future proofing, I use a 5070ti 16GB Gigabyte OC myself and had no issues with this power supply.

    This was great computer running smoothly my computer with my old power supply was actually turning off and turning on and I couldn’t figure out what was going on until I figured out that I added a new graphic card but didn’t change the power supply.

    Corsair quality as you would expect. The cables are some of the best out. Needed to upgrade from 850 watt to this 1000 watt as my overclocked 11900K and 3090 needed more power.

    I have been using this power supply for a few months now and it runs great it handles a 13900k and a 3080 v2 no issue. I have been using corsair power supplies since I first started building PCs and so far have not had any issues with their quality. Works well, and they have been reliable for me for years. If you require a 1000w this is one you should consider among the plenty of other great power supply manufacturers.

    enough cables to do anything, only downside is i wish corsair gave solid 8 pin gpu cables instead of just 3 6+2 cables , solid 8 pin is a cleaner look. was very easy and self explained install , no instructions needed, each cable had description so you knew where it went, enough cpu cables to power a quad zeon, corsair if you see this pls read

    I have never been inside a computer before and was expecting it to be difficult to replace one. It was very easy actually and only confused me a little bit. 5 out 5 for how much quieter it is compared to the 850 i did have.

    Second Corsair PSU i've purchased and they work perfectly. I had the RMx 850W before this from my other build. When I started building my current PC, I needed a stronger power supply, and I originally purchased the EVGA supernova G+ 1000W Power Supply. EVGA has always made great quality products, but their PSU was giving me a really annoying and loud coil whine. I eventually returned it and went back to Corsair. I'm pretty sure I'm just going to stick with Corsair PSU's moving forward. They work perfectly and i've never had an issue with any of them.
