Customer Ratings & Reviews

The Corsair RM1000x delivers flawless, stable power even under heavy GPU loads. It runs whisper-quiet, stays cool, and the fully modular design makes cable management effortless. Build quality feels premium, and efficiency is top-tier. Perfect for high-end gaming or workstation rigs this PSU gives long-term confidence and clean performance every time.

All the power I need, with the being able to use only the connections I need makes for the cleanest PC builds. Corsair is #1 in my opinion. Also this is super quite with a fan control knob on the back.

I was looking to upgrade my power supply in my prebuilt pc since I was fixing to upgrade my cpu (to a ryzen 7 9800x3d) and video card (to a 5070ti). I needed one that offered the wattage necessary (and the correct connector for the gpu) to run my new upgrades on top of everything else this pc has. This was the power supply I ended up choosing. It fits snugly in my pc’s basement and is mostly out of sight. The modular nature of the cabling was partially useful but since I needed almost every cable it did take some doing to keep the excess cable length tucked away. The cables themselves were easy enough to install (into the supply itself), mostly just bring matching the clearly labeled plugs into the clearly labeled ports. I won’t speak of ease of connecting everything to the motherboard and other accessories a pc may have as that’ll vary from pc case to case, motherboard to motherboard. It runs really quiet though this depends entirely on how high you have the fan turned up. It’s not overly noisy when turned all the way up but is quite noticeable. Thankfully I only need to turn it to maximum during the summer months. Normal fan speeds are almost whisper quiet. Finally, the wattage is more than enough for my needs as I am not currently running a 5080/5090. At no point in time have I experienced throttling due to not having enough power. It even comes with an on/off switch which could be handy. All in all this was a great purchase and I whole heartedly recommend it to anyone looking for more power but don’t need 1200 watts and has a pc case that it fits into.

It has all the power I need! So make sure it has all the power you need. Everyone needs their own power. Is 1000 power enough power for you? It's probably enough power for you. If it isn’t and this review is something you are depending on to see if it is enough power for you then it’s a sign you need to double-check how much power you need, because remember everyone needs their own power, and no one knows how much power you need but you. So check but this is probably plenty of power for most people. It’s quality power if it’s enough power.

Corsair with another super solid product. I purchased this when I bought my 5080, April 2025. With the increased power draw and new 12v power connector, I decided to upgrade to this from the corsair cxm750w. I have been fortunate to have everything in working order. I was impressed with the selection of included cables and appreciate the redundancy of some of the cords. The manual knob for fan speed at the back is a nice inclusion but ultimately gimmicky because of placement. Works wonderfully and keeps everything well fed even with some decent overclocking (cpu+gpu+memory) .

Great for my pc build needed something that could handle my rtx 5089 and this psu did it perfectly also very easy to install and comes with different cords to suit different computers overall great psu would buy again for future builds

The Corsair RM1000x is a top-tier power supply, offering a blend of performance, efficiency, and quiet operation. It's an ideal choice for high-end gaming or workstation builds that require reliable power delivery. With its fully modular design, solid efficiency rating, and extensive protection features, the RM1000x offers excellent value for those who need a powerful and long-lasting PSU.

Got this right after I bought a 5070ti. So glad I did. Made powering it much easier and safer. I hid it behind a 12" touch monitor in my wall mounted TMNT themed PC. Looks cleaner with the one 12 pin.

I haven't had any problems at all! I bought it because I recently got an RTX4090 and it definitely gives enough power output. It's really a great PSU, would highly recommend if you need some power.

I paired this with a 5070 and an i7 14700k great power and I like the feature for controlled fan speed

It is rock solid no performance issues and silent fan ,cables are strong quality.

So far so good. It's having no issues powering my 7800X3D and 5080. The 12VHPWR port means I don't need the adapter. Cables are of a higher quality than I expected. They look good and come with cables combs, so it's a fairly clean look without having to get custom PSU cables.

I have a very demand 5080 Nvidia card; I've been having instability issues but once I changed over this power supply, zero problems. I've ran 24 hours stres tests, zero issues. Absolutely quality product and I am thrilled, the power capacity is more than enough for this card, and the included special cable is absolutely fantastic so no complaints! I'm thrilled

Awesome power supply, comes with nice cables and love the modular setup for it.

I had issues with my current power supply having issues after doing some upgrades to my tower. I bough this because of the brand name and warranty and am very happy with how everything is working now the past couple months.

I went from a 3080ti and ThermalTake 750W grad tough power RGB PSU which had served me well for about 8 years to a new 5080 GPU - Asus TUF version. I wanted to ensure stable power and also wanted the new PCIe connector for a simplified install. This bad boy did the trick!

Just enpugh for what i need, anymore and id have to wonder

Excellent for protecting the components of my new gaming PC. Great voltage protection. You can also control the fan speed, which is great. Highly recommended.

The RM1000X is a great psu it has great wattage and a great price point I think it’s good overall well worth it

Very great had everything I needed tried to use something else and do not work out
