Customer Ratings & Reviews

I’m loving this power supply, stays cool, has no coil winding and powers everything perfectly

Really solid power supply for anyone building a high-end gaming PC. The 1200 watts gives you plenty of room for powerful components and future upgrades. I also like that it's fully modular, so you only have to use the cables you actually need, which makes cable management a lot easier. The build quality feels solid, and the black design looks clean inside the case. It's definitely worth considering if you're running a powerful graphics card and want a reliable power supply without having to worry about upgrading anytime soon. Overall, a great option from Corsair.

This PSU was exactly what I needed for my small form factor build. It’s quiet, runs cool, and has enough power for my high-performance components. The fully modular design made cable management a breeze, and installation was straightforward. Been running it for a couple of months with no issues at all. Would definitely buy again and recommend to others!

Quiet and is a powerhouse. have used for 6 months of overclocking and no issues.

Excellent build quality, no problems, silent as an owl. Included Wires are all black, not braided or anything and just long enough for my case.

Worked great out of the box. No issues, easy to set up and powered everything I needed it to. Plus I got it on sale!

I went from a 700 W to this and do NOT regret it. Upgrading to a 5080 (which this PSU was much needed for), it's 50-series ready, silent, efficient, and worth it across the board. It was very easy to install and replace my old PSU with this one. It absolutely handles everything i throw at it with my demanding GPU; it's a powerhouse

Very quiet and an amazing product, this fit very well with my 5090 and I have no complaints.

works fantastic no issues during install, price was great.

Worked as advertised. Form factor is actually smaller than the 750 watt PS it replaced. Easy to hook up.

The power capacity of the RM1200e allows for amazing future proof upgradability and stability even when overclocking!

I would like to recommend this psi, if you have a card like 5090 or 5080 the most powerful cards you need this

I have a liquid cooled gaming computer system and my seasonic vertix power supply went out. I purchased this power supply and everything is working perfectly!!

This power supply lets me monitor precisely how much power is consumed both from the mains power as well as how much the motherboard the GPU consumed. Very stable and capable power supply.

My power supply died unexpectedly and this do the trick. I didn’t want to spend a million dollars - and this has been working great in my gaming PC for a few weeks now. Easy to install. I like how you can disconnect the cables from the back of the power supply. It came with a lot of connector types. Got my PC back running on the first try! For the cost, I was surprised on how quiet it is too.

Excellent PSU works great for dual 7900 xtx with plenty of room for a decent CPU

Just installed and worked out of the box. It’s a 1200 watt psu, just need it to last now. Easy install and if anything happens I will update this review otherwise so far really good.

Very powerful and one of the top brands would recommend

No Issues, grreat for cable management. I Love it.

Great PSU, powers my 5090 fine. May have been able to get away with 1000W
