    I’ve had it for a few months. This is all I have to say. It’s reliable, and customer service of corsair is great. Definitely one of the best choices of PSUs

    1000w watts of 80+ goodness. I've read that while Nvidia states an 850w PSU will power an RTX 3090, I've seen reports of issues at that wattage. I figure this has to do with the amp/rail configuration, but I decided to play it safe and go 1000w. This doesn't disappoint. I went with Corsair because I had one of their PSUs fail around 5 years ago, and their RMA process was great. They cross-shipped a replacement with 2 day shipping, minimizing the burden. So they've earned my trust.

    What can I say, if you're looking for a 1000W PSU look no further to this beast. Corsair has yet to fail me on quality and performance and this PSU is just another amazing product by them!

    This beast can handle just about everything you throw at it. My only complaint is the cables it comes with. They put a ridiculous amount of tape around some of the ends, and it can make cable management very difficult.

    Great Modular power supply. The options to pick which cables you need is a welcome change to supplies. I replaced my older and less wattage Antec so can’t comment yet to reliability as Antec lasted forever….

    Good working power supply. Lots of cables easy to see labels to plug in cables. Got scared for a bit since the fan doesn’t power up until a big load is used. Otherwise quiet and heavy.

    Good modular power supply with sharp looking included cables. Does everything I need and keeps cable management under control. Also allows you to order custom cables being modular but so do all modular power supplies.
