    • Nice PSU
Style: RMe (2025) ATX 3.1, PCIe 5.1 Size: 750 Watts Color: Black
Works great, looks great. Easy to install, and provides more than enough power (according to your own setup of course). Noise is minimal, its not louder than any modern graphics card; you'll hear the GPU before the PSU. It does give a very loud thump when it turns off, but other than that, perfect piece of hardware. Always bought Corsair, never disappointed. Cabling takes a sec, but being able to mix and match allows for excellent cable management. ... show more

    • Its Corsair so you know its good
Style: RMe (2025) ATX 3.1, PCIe 5.1 Size: 1000 Watts Color: Black
Amazing power supply includes all cables i could possibly need for my build. the 12v Rail produces constant even power levels that my GPU truly enjoys. Having owned several corsair products in the past I am confident in the build quality of this unit and have yet to have any power issues at all, installation is simple and it did include the screws and zip ties for cable management. this power supply has wonderful performance and provides a great value for the price as one should expect from Corsair. ... show more

    • Quiet, powerful, and modular — flawless PSU
Style: RMe (2023) ATX 3.0 & PCIe 5.0 Size: 850 Watts Color: Black
This is one of the best power supplies I’ve used. Fully modular design makes cable management a breeze, and it powers my high-performance build with no issues. Runs silently, even under heavy load. Corsair’s quality is unmatched, and this unit proves it. Highly recommended for serious builds.

    • Great for system builders.
Style: RMe (2025) ATX 3.1, PCIe 5.1 Size: 1000 Watts Color: Black
I'm a PC builder and I can say, I plugged this in and my system came right up. I got the 1000w one because of the graphics card. If you have a high-end gamer graphics card that can do VR, then get at least the 1000watter. If you're running a basic system, you don't need as much power. I pretty much leave my system running 24/7 and it goes in to low power mode. So far, no problems. Great power supply for system builders. Came with all the cables. ... show more

    • Good psu

It's worked well and it is a very good wattage for very good price. It gets pretty hot but the built-in fan works pretty well. It isn't that noisy either.

    • Works Perfectly, Cables Backwards-Compatible
Style: RMe (2025) ATX 3.1, PCIe 5.1 Size: 850 Watts Color: Black
Oddly powerful enough to run an RTX 3090 and RTX 3070 together with a Ryzen 7 9700X CPU and ~12 other parts. I probably should have gotten the 1000W model instead, but I'm dumb and didn't plan ahead. Included all mentioned cables and a few other things. There are not enough included cables for both my GPUs, so I had to borrow a dual 6+2 cable from an RM750e 2019 model. Thankfully, all RMe series PSUs back to at least 2019 have full cable compatibility. Corsair has a helpful table on their website for which PSUs have compatible cables. ... show more
