★★★★★Good price on a top-notch power supply from Corsair
If they have the factory refurbished, get it! Great quality, and it came looking brand new. All cables, and the power supply, looked amazing. The only thing to keep in mind is (a) the box is brown not retail, and (b) the serial number will be marked as refurbished. But overall great deal and it's working great. My setup is Ryzen 9 5950X with an AMD Radeon RX 9070 XT. Holding up well!

★★★★★Refurbished gem!
This was available as a refurbished unit at a decent savings vs new. Came with a longer warranty and return window than if I bought it new. Didn’t come in the original box (duh) which I could care less about. Everything about it screams brand new. Even smells new! You know what I’m talking about. Cables were perfectly new no signs of use. No instructions but do you really need them? lol if so go look on the website. I got this particular PSU because I had seen it used many times with my motherboard so I knew it would not have issues. Plus Corsair always makes pretty good stuff. If a used or refurbished one is for sale and you are on the fence, BUY IT!!
