Customer Ratings & Reviews

Runs completely silent and cool even with top shelf hardware. Im using it with a 7800x3d and 7900 xtx (both overclocked), the graphics card pulls 3-400 watts alone and this PSU doesnt even break a sweat running at 85% efficiency under load. No coil whine, and you can monitor draw/ adjust the fan curve in ICUE. I'm using it with corsairs optional braided cables, but the included ones seem high quality. I didn't use the pci e high power, but it does come with one for you Nvidia folks

Corsair make the best quality pc products. This is the power supply I put in my monster machine. It is important to have power head room. My machine is running an AMD Ryzen 9 5950x, Corsair 128 gigs of DDR4 RAM, NVIDIA 3080 TI GPU, two Samsung 980 SSD m2 hard drives, a Samsung 1 tb SSD, and a 4 tb WD black hard drive. Everything runs great with this power supply.

I got this while on sale as part of a brand new system for 2023. Not much to say that hasn't already been said. I have been using an RM850x in my previous build for the last 2 years and just like then, I'm happy!

Great psu for the price! I have i7-9700k with z390 aorus pro ,32gb ram , NVIDIA Rtx 3070 along with two 144 hertz monitors. Over clocked my computer with plenty of power to spare. 10/10 would recommend

great, had to buy in case my new gpu was going to need demanding power draw

The modular plugs is what makes this PSU shine. It brings ease of install for your build and packs a punch with it's wattage. Quiet and running my new system perfectly so far.

Its fully modular which makes for easy cable management, you only include the cables you need.

Purchased with getting one of the RTX 4000 series in mind, I previously had it connected to a 3070 ti and 5800x. I knew I wanted to purchase this particular one for better power draw on higher end graphics cards, so far it hasn't disappointed me. I have my RTX 4090 and R9 5900x along with 8 case fans with rgb, two M.2 ssd's two fan push pull configuration cpu air cooler.

Wasy instaliation super cable management loved it 1000w im gone out that 4070ti now

Unbelievably powerful, steady performance and ultra reliability

I have not too much to comment on with power supplies. This one looks very nice, when you get to see it. It comes with all of the cables I needed and more, and sitting on my desk I do not notice the fans on it all too much.

Lots of power with only as many cables to manage as you need to use. No more cramming unused power cables in the back of your case.

Very solid psu for the price, doesn’t overheat, currently using a 3090 with it and have had no crashes.

Excellent power supply so far. Works well with a 4090/14900K, with plenty of auxiliaries.

[Employee of bestbuy] Does everything i need it to, especially power the new 4090 GPU. 4 sticks of ram and all 10 rgb fans.

been amazing super low noise powering my 4090 and 13900ks perfect

Had the power but I couldn’t connect my 4090 to it so that was the only downside over all great product if you can use it

Great PSU, works perfect in my new build with a ASUS 690 and ASUS 4090 GPU.

Flat pcie cables make it easier to cable manage but they don't look as nice as round ones
