    Haven't had the power supply long but I know that corsair is a good brand and so far it has been working as intended. When I went to pickup my product from best buy, it was quick and easy and the store staff were very nice. Overall, I am very happy with my purchase.

    The power supply is perfect for my RTX 3080. I have a prebuilt gaming PC so installation was a little challenging. The hardest part was cable management but it works perfect no problems. and very quiet.

    Obviously can’t say anything crazy about how effective it is (I haven’t had it long and shouldn’t really notice it doing anything) but it is quiet and the cables are much more manageable than my previous PSU.
