Customer Ratings & Reviews

This is the second one I’ve bought, because the first one worked so well. I bought the same one for my kids build.

Works great. Much better than my old power supply, I needed something that gave a bit more power and this was it.

Everything was included as expected. Its been working like a charm, running 24/7, cause you know... mining sruff

Works as advertised, and it's fully modular; I used this for an older system, and the fit was perfect as well.

Excellent quality, doesn’t seem like the finish would scratch; the fact it was so cheap for an 850w power supply is amazing.

Its really quiet and i like how they packaged the item and the case you get with all your cables you may need.

Great power supply and very nice black cables. Easy and quick setup. Works even better now with the look of a white and black build.

Works great. Replaced an old power supply that was causing random crashes. The modular design keeps wiring neat.

Great PSU. This is all you will ever need if you are planning to run a single GPU system. I have an i9 10850k (10C/20T) and a massively overclocked 6900xt running in my system and this PSU handles them with ease. In fact, it doesn't even seem to sweat as I never hear the PSU fans. The GPU can draw up to 370W in maximum load, CPU can draw up to 225W. Even with 575-625W of power consumption, I never hear the PSU fans. Big thumbs up to corsair.

The power supply itself is built very well and it is clear Corsair knows what they're up to! The user experience, however, can use a bit of work. Namely, the capacitors built into the cables make them hard to work with, and the labeling on the back of the PSU is not as clear as it could be. Specifically, the naming should map directly to the slots that are for any given device, which companies like Seasonic do well. Otherwise this is a fantastic product that I hope lasts me 10+ years!

Corsair products keep getting better and better, easy to install and connect. Great for the new motherboards and gpu

Trusted PSU as expected for Corsair, 850w is more than enough for a 3080 and a <5.GHz CPU clock.

Was using an old 400 watt after upgrading system, kept getting shut downs. Switched to this and haven't had a problem since.

Good power supply. I really like that the fan doesn’t spin when not under heavy load. Supports my 3080 just fine.

Great psu. Added this to my new 3070 build with a Ryzen 7 3700x and have plenty of headroom to power my system.

Great replacement for my 6 yr old Velocity Micro tower. Fit perfectly and the assorted cables allowed me to match what was needed for the system.

Great nice and has a good overall premium quality to a all white build.

Good power supply ror high end builds. Cant say much besides that. Its just a nice modular power supply with more than enough slots.

Good price for a simple modular PSU. What can I say, it works and is a reliable name!

All of my mining rigs use this power supply and has enough power to operate 4 3070s when they are undervolted. To get 4 3070s to work, YOU HAVE TO KNO WHAT YOU ARE DOING..... If you dont know how to set the power limits on your GPU then DONT power 4 with this PSU... So far it runs great and has been operating 24/7 with no issues. Has plenty of wires to hook up all the items you may want. AGAIN, dont use if you dont KNOW how to measure wattage.
