    Great product and it’s worked hard. It powers a 3090 and two 3060ti’s plus an overclocked i9-9900k 24 hours a day, 7 days a week. I like this Corsair psu line, hence bought several varying watts over the years.

    Very solid fully modular power supply. Wiyh yhe new technology coming out in GPUs amd CPUs there is a higher need for more wattage in a PSU. This is a small package, not too expensive, and works like a charm.

    I needed this PSU when upgrading to a 4090 from a 2080ti with a 650-watt PSU, so I stayed with Corsair and couldn't be happier.

    1000w, modular, very reputable brand. Gold rated... It's either Seasonic or Corsair for me; this thing should last me for years to come.

    Great Modular PSU. Comes with enough cables for most needs. No coil whine, no loud fan. Does not have "smart features" that the HXi series have to connect with iCUE, but it still works fine

    I bought this since Corsair makes the special power cable for my 3090. I had a different brand 850w that was also gold rated doing the job but I like this one better.

    A 1000w for only 200 bucks when most places are selling these for over 300 is winning. This is nice to have for a rtx 3090 or to run multipul video cards.
