Answer by Kristian on 6th September 2021
You could in theory connect 3 cards, however, the actual wattage will be a limit before the cables are. - Kristian N

Bought this to power a 3080Ti, seems solid so far. Warranty lasts a long time too, which is nice.

Quality power supply. I've never seen the fan spin apart from while booting so it's practically silent.

Great modular psu, plenty cables, nice accessories and some good old fashioned instructions. Replaced my 10 year old corsair 750, kept to the brand as they have never failed me yet so hoping this one does just as good a job!

CORSAIR has history of running out of products even before pandemic. FIX THIS PLEASE CORSAIR!!! While building new PC this corsair PSU was last to arrive. Product was out of stock everywhere waited 15 days. Worth the wait though....not disappointed at all.

The Corsair RM850X is a good PSU with all the cables,connections and power anyone would need and is quiet in operation and the 10 year warranty is an excellent period to be covered

Excellent product, works really well and copes with all the accessories in my gaming computer, cannot fault it.

Can't beat Corsair for power supplies. It's efficient, it's silent up to 340W (and very quiet after that), and it's got all the cable options you could need. They're also a decent length, which is always nice. I paid 100, which is incredible value. At the current price (115) it's still a 4/5.

The best power supply I've seen to date

i use it for i7 9700 + RTX2080. I only use it for 2 days, but it seems good, reliable.
