    I've been using this for over a year, originally to power my 3080 Ti and now my 4080. No issues whatsoever, and it's survived multiple power outages while connected to a surge protector.

    I needed a larger power supply to properly support a new video card, and this really fits the bill. Having modular cables helps as well. It really has the power to support a higher end system.

    Great PSU for higher-end GPU, got this with my 3080 ti. I like that the power cables and such you can plug in what you need, it’s not already built in, also comes with some cable ties for cable management, which was also nice.

    I installed the PSU in my old rig and it is powering a RTX 3080ti without issues. Got all new components coming that will definitely draw more power and test it more then the current rig but I have no doubt it will provide sufficient enough power.

    Honestly I'm just writing this review for a chance to win a $400 gift card. That being said I've only used Corsair made power supplies in my builds and have never had a complaint and still don't. Nothing particularly noteworthy here. Its a solid PSU.

    I needed a new power supply for my new Ryzen 7700x, RX6900XT build. For the money, there isn't a more reliable 1000W PSU. Along with a 10 year warranty from Corsair, IMO the RMx series are the best power supplies.

    This is the power supply your girlfriend tells you not to worry about you little 600watt boi. This guy eats Japanese capacitors for breakfast, e-bois for lunch, and any flagship nvidia gpu (lol roasted). Fully Modular too which is cool.

    I received a different 1000W PSU from a friend and died on me after just a couple months. I was annoyed to have to spend the money on a new one, but this has been very solid now for multiple months and hundreds of hours of use. Highly recommend Corsair PSU.
