> 3 dayHappy with this PSU! Matches the aesthetic of my build, was easy to install, and the cables were easy to manage with my case. Works like a dream and is very quiet. I havent tested power efficiency yet and If i have any failures in the future, Ill update the review, but I dont have a single complaint thus far. 5/5

> 3 dayCorsair quality always on point. I saw some negative reviews about this and was concerned about ordering this but since it wasn’t available it Best Buy or anywhere else I decided to order from Amazon and I am happy to say I got it in a perfect condition and it works perfectly no coil noise under pressure or super quiet when idle. Build quality is solid as well. Price was decent it was msrp I mean nothing is msrp at this moment but it’s fine I think I got a good deal considering the chip shortage around the world.. very happy now let’s see how long does it last without giving me any trouble that’s the real test.. I will update the review if I ever get any problems with it.

> 3 dayNot buying from Corsair again. I thought it would be a one in a million chance but no, mine came dead. I didn’t get a replacement and instead I bought a Seasonic Focus 850w psu. Worked fine when I got it and still works greats

> 3 dayGot the 650w version first, but the PSU didnt power on. Switched to a 850w PSU and everything works great. Very quiet. the cables i find are longer than what i would have wanted but it was easy to cable manage as well.

> 3 daygreat really great. i just wish a bought more wattage as i now need to expand my workstation a bit and i am going to be pushing 85% of 650 which is still ok but not ideal. regardless of that this is truly solid product.

> 3 dayUpgraded from a 550 off brand that came with my original build. Biggest upside was that my original was. Not fully modular and this was. Like why do they even make power supplies not fully modular? This was a huge step up for me.
