    If you need a PSU and don’t want to worry if you have enough watts, you can’t go wrong with Corsair’s RM1000x Comes with plenty of cables. Take whichever ones in and out as needed. Very sturdy, durable. Easy to use power switch

    Great quality as you would expect from Corsair. I upgraded from a GSkill 850 because I was having random crashes. After installing this power supply, I am no longer experiencing crashes and my system runs great no matter what I throw at it. The modularity is great and the fan is quiet. The only thing I wish was different are the PCIe cables. I use extensions but I would have probably used the included cables if they did not have the dongle. This comes with a 10 year warranty so don't bother continuing to research, just pick this one up!

    Corsair has never failed impress me! I had a unit that was 750W S. Flower. It kept restarting my pc when playing games. I think it was the 10900k RTX 3080 power draw. I put the 1000w unit in and now power to spare. And, for me its future proofing.

    You can have never enough power for your rig. As technology grows, like GPU power consumption, you need more ponies in your rig. Hopefully 1000w is enough to carry me to the make upgrade. It definitely runs quiet when you are running full load and the does not generate that much heat which is surprising. Corsair out did themselves with this line of PSUs.

    Excellent power supply. I bought this for a 4080 video card and it did the job very well. Keep in mind it only has 3 connectors for video so you'll need something larger for a 4090 card.

    This has been a great power supply for me. I like how the cables are sheathed for a cleaner look and the full modularity helps keep the build cleaner by eliminating extra wires. The body takes up a fair amount of space, but that's typical of a power supply this size.

    Great PSU with easy cable use for cable management as long as you're patient enough to do it. Even if you're not worried to much about cable management this fully modular Power Supply Unit let's you keep the cables you don't use unplugged and out of the way to make it look clearer then what you tried. Corsair uses great quality parts from Taiwan & Japanese.

    Corsair PSUs utlize the same cables across models, so if you upgrade to a new PSU, you don't need to rewire everything, just swap the PSU and plug in the cables to the new unit. It's very nice and very clean and quick.
