Upgraded from a RM850 to this psu to ensure I have enough power supply for my 4090. No problems at all. Everything fits perfect in my 5000D airflow case.

This 1000W is quiet and does the job well. The cables it comes with are very solid and long enough to run the length of a large computer case. The build quality is great as with all Corsair products. If on sale, this is a great buy.

I love this beast of a PSU. It’s more than enough for my 4080 and 5900x combo since my 650w wasn’t going to cut it, and I will be using it for years to come.

If you care about cable management, tons of power for your pc and a quality product then this PSU is for you. Not only is it fully modular, Corsair sells colored sleeved cables for this psu to match your system and they are fantastic.

Was a little overkill for my system at first. Recently just upgraded to a newer bigger motherboard and AMD chip with my 3080 GPU. Works great! Haven't had any issues.

Needed more power once I got my new GPU(Suprim RTX 4090) This power supply unit being modular makes it pretty easy to set up too. I give it a 4/5 stars! The picture added with this is the PC build with the power supply unit powering everything to show it holds up with a pretty good gaming rig..

This power supply leaves me with enough power to eventually upgrade to a 40 series RTX. It also performs as expected and will hopefully be in my PC for the long run.

Works great. Modular cables are nice. This PSU is pretty long so cable management is a little tough in a smaller case

This is a great unit! Recommend CORSAIR PSU's***`
My last psu 750w which is 8 years old is still kicking!
I got this for my new build and it comes with a 10 year warranty!
I started working on computers back when CS 1.5 was a huge deal. I've installed many different power supplies for friends and family. None of these ever failed, just retired for upgrades! I'm sure this unit will stand the test of time.
