You cannot have too strong of a PSU. The PSU is rated at it's maximum draw available, not how much it is constantly putting out. 850W is certainly overkill, but excess is always better with a PSU.
Sorry, there was a problem. Please try again later.A 850w PSU is more than enough to run this card along with the rest of your system as Nvidia recommends a 600w PSU for it. However, having a bigger PSU saves you the trouble of replacing it for future upgrades.
Sorry, there was a problem. Please try again later.Lol, I cant believe that I have to say this, but the power supply / card only uses what it needs, you could have a 10000W power supply and the card would only use what it needs. So no, there is no such thing as "too much" but there is a such thing as too little. I'd say you need more that 650, and since you have 850, your fine.
