Clean, efficient, and easy to use. Running my 10850k, 4070, and all the other crap shoved in my tower with zero issues. Modularity is excellent for keeping your system from being a spaghetti mess by only using the cables you need. Included molex cable is excellent if your still using some older hardware or fan hubs. You get what you pay for and corsair is worth the cost to keep your system running stable.

As I just recently upgraded my computer to the point where it was basically a new build, I figured I needed to up the PS game as well. This unit replaced an Aresgame AGV500 that I picked up while out parts hunting for good deals. This is my 2nd fully modular PS, the first was a Seasonic SS620 that came in a Fractal case that I purchased. Unfortunately, most of the additional needed cables were missing *video card in particular*. So my options were to use my questionable quality PS on my much more expensive hardware, spend $80 dollars on cables for an older 620w PS, or actually buy a NEW PS. This unit fits great in my NZXT case, all the cables are long enough to go to their respective components and be neatly managed. The fan is quiet and only on when it needs to be. The black finish matches my case nicely and the warranty is stellar. Current setup is: Gigabyte Z590 Ultra Intel 11th gen 11700k Teamgroup 32gb 3600 Teamgroup 2TB Cardea Gen4 NVME Nvidia RTX 3070 Machine runs rock solid. The price point on this power supply is a fantastic value.
