Customer Ratings & Reviews

This is the perfect addition to your build if you’re building a high end pc. It is very quiet and reliable. No issues with it since day 1.

Perfect power supply, no issues. I had no problems installing it as well, super simple.

Not a bad power supply it's pretty quite came with all the cords needed with extra and with 1k watts you'll never really run out handles most newer parts and what also nice is that you don't just have a lot of cords coming from the power supply forcefully like other companies it has none forcing you to use so you don't have extra laying around

I make the most of this power supply for sure. With a Ryzen 9 5950x - Radeon 7900xtx - 64GB 3600 RAM - Gigabyte B550 Gaming X - wireless card - 2 m2 drives - 1 ssd - Valve index VR - Wired mouse, keyboard Razer Tartarus, Razer RGB mousepad, audio interface, headphones, studio mic, speakers, ethernet, dual monitors and this thing has absolutely no problem keeping up with that.

Put this in my PC after my old power supply dealt with one too many Texas power outages. Has been a real trooper. Runs my rig quietly and without getting hot.

Quiet psu. No issues. Good price. Plenty of cable ports.

fit in my corsair 5000d perfectly and takes care of my power needs with alot room to spare. comes with a ll the types of cables needed to do what ever your hookin up, the assortment of all the different cables is impressive.. And the quality is great. If its got the name Corsair on it its gonna be a good product.

Overall a great power supply, no issues so far. Cables are great.

Love it! Good looking and a ton of power plus jt stays quiet

This is a rock-solid PSU. This is my second RM1000x, with the first powering a 5950x/3090 setup and this one running a 7950x3D/4090 rig. ZERO COIL WHINE. I originally had an EVGA 1300P+ platinum in the 7950x3D, but the coils SCREAM in that PSU. Stay away. The Corsairs are super quiet with no coil whine in either unit, not even under stress testing. Highly recommend!

Great, does everything you need it to plus some, including demands

This psu is pretty quiet and it can and will power any gpu

This is a great, high-capacity PSU with plenty of cables. Everything works as expected and it’s a great value 1000 W unit.

Great product. Behaves as expected. I don't hear any noise from the device and it installed without any issues.

Haven't had any issues with this and it fits my medium size case

When it says the fan is 0RPM they mean it. It is SUPER quite and works great. Haven't had any problems since I switched out my old 750 for this one. And for the power supply difference I am getting with it, the size difference isn't that much different. It still fit fine into my case which is on the smaller side. 10/10 would buy again.

I build and fix a LOT of computers, and I've seen power supplies fail in just about every way imaginable. The things responsible for converting wall power into precisely controlled DC outputs take a lot more wear and tear than people generally imagine. Capacitors wear down with age leading to voltage drops, cooling systems seize up and start grinding, I've even seen a couple short out and catch fire. But I can count the number of Corsair power supplies that have broken down on one hand - which is why they've been a regular fixture in my personal builds for over a decade now. Yes, it is a somewhat pricey unit. But Corsair's quality control and engineering alone is worth the premium given that a PSU failure can easily end up frying every other part in a system. And the RM1000X has everything you need for a high wattage modular unit. The cooling fan is quiet even at high RPMs, voltages are solid and high enough that the system should be able to remain stable even as the parts begin to age, and the modular cabling system means you don't have to deal with excess bulk for your system which could lead to added strain or damage that could lead to shorts. I picked this up for my home VR rig which is running an overclocked 12th gen i7, a 3080, and a whole Christmas tree's worth of lights and I fully expect that I'll still be running it in ten years' time unless standards change or PSU power draws get high enough that they require a whole new PSU.

I rebuilt an existing desktop computer, replacing 8 year old components. This was kind of an almost afterthought, but glad I swapped it in!

Make sure that you use the cables included and switch each one out to avoid any issues! This is an absolute powerhouse of a power supply and can handle anything you throw at it in just about any machine. Great quality on everything down to the wires themselves.

wellll was sorta easy. Every thing fit my case perfect it is long and heavy like a brick, but i squoze it in okay barely. Quality power supply, Cables are quality also and marked. A fith grade genius could do it ;) Upgraded 2070 card to nvidia 3080ti. Upgraded to this power supply. I got one major issue. Cables with this power supply do not fit nvidia 3080 ti. Arrrggggghhh!!! you will have to order these seperate, CORSAIR - 12-Pin GPU Power Cable, Sleeved - Black. cables that come with nvidia 3080 ti do not fit this power supply. I say, whiskey, tango, foxtrot ! Other than that i love it.
