    I really needed a psu that could handle my 4070ti. So i got this and it worked perfectly. It came with enough pcie cables and everything else. I know that the 4070ti doesn’t need that many watts but this was on sale and was around the same price.

    Does what it's supposed to do, have had no issues with it so far! You only have to plug in the cables you need which is great for cable management.

    This replaced my old Corsair 650, and has been supplying the rest of the computer like a champ. Quiet operation just as advertised, and fully modular. Would definitely recommend getting it if upgrading parts.

    Upgraded to this from my RM750x specifically for adding a 3090 to my PC build. I had no problems with the RM750x and none with the RM1000x so far. The build quality is excellent and the fans are quiet. Corsair has a great reputation for the RMx series and I can confirm this.

    Honestly the 850w is just as good I only went with the 1000w cause sooner or later I plan on upgrading and with that beating said I don’t have to worry about buying another psu if needed cause I got the big boy and think it was the best decision!

    Upgraded to this beast to power my upgraded rig. This bad boy puts out plenty of power for my i9-1300K/RTX3090 system. The modular design is great for keeping the cables nice and tidy. I have always had good success with Corsair products.
