Customers love the RMX Series RM1000x power supply for its overall performance and ample power capacity. Many appreciate its quiet operation and the ability to fine-tune the noise level. Users also find the cable management to be clean and the installation process easy, with the modular design contributing to a tidy case. A small number of users reported no coil whine.

    Upgraded from a 20 series card to a 50 series card and needed a 12vhpwr cable, went with this corsair and so far so good, playing for long hours and the only warmth im feeling on the cable is from the fans blowing the hot air off the card on to it. Stable, and works great.

    Replaced my nearly 10 year old RM 1000 with this one for my new build and couldn’t be happier. The other one was still working when I replaced it. Corsair has upgraded the cables that come with the PSU. They are no longer in those awful woven sleeves that don’t bend. Much easier to route the new cables.

    After buying the RM1000e and having the electrical arcing sound issue that the entire E series has had since the first where produced(which i didnt know before buying) but this RM1000X has been perfect, all the wires even connect better and come out easier on removal, all and all im very happy with my choice to spend the money again to get the higher end version.

    [Employee of bestbuy] Upgraded to a new graphics card and i had the older rm850x series. I bought the newer model that had the newer 16pin 12vhpwr built into the power supply so i didnt have to use an adapter. Thought i might as well upgrade to a high wattage too. So far, works just as advertised.

    Looking for the power? This one will give it to you. It's got the connectors needed for running top notch power accumulation. You'll love it.

    Cosair has a way of showing off how "Power-ful" it is! Competes with big dawgs but affordable for all. I would recommend this. Easy to install and works quiet and good.

    Excellent PSU. Upgraded from the old RMX1000 (20201) to this version and my coil whine is completely gone, RTX 4090, i7-12700K based system. Not saying this will fix it for you if you have this issue, but I am incredibly happy with it, as I tried swapping out a bunch of other components, including the GPU itself, motherboard, ssds, and it didn't fix the issue.
