Is Corsair RM850 80+ Gold PSU enough for running one Antminer C1?
Yes, although I still prefer the 1000 as an investment if you're buying a new one.
I can confirm the rm1000 is great with theses. I had a cold ambient temps and PSU was in its "quiet" mode.
I have got conformation I am being sent 2 pumps as replacement's. I bought a molex to fan connector so I don't have to worry about my wire frying boards.
All said it looks like I am losing around 2 weeks mining on 2 C1 machines. Down 2 board fan controller's on 2 separate boards. Lost higher priced coolant. Paranoid and bought 2 extra pumps, and molex to fan boards. With extra parts I ordered I am hoping to lose only around a week, but it came at a premium.
I will know more when I get all the parts from RMA.
I highly suggest 2 things after all of this so you don't lose mining time.
