I'm thinking about what upgrades I'm going with in the next few months and wanted to check what PSU I needed with the upgrades. Looking at wattage counter at Newegg and partspicker they were way different.

I'm trying to SLI 680s, and partspicker shows 610w vs Newegg that says 811w.

The setup I want to eventually get to is this:

I just don't know if I need an 850w or a 1000w PSU. Going by partspicker 850w is plenty, but Newegg shows 811w and no wiggle-room. So then I'm thinking 1000w PSU would be needed.

Anyone have a similar set-up and knowledge on this matter?

Recommend 850, tier 2 PSU:
Measured power consumption one card

1.System in IDLE = 144W
2.System Wattage with GPU in FULL Stress = 307W
3.Difference (GPU load) = 163W
4.Add average IDLE wattage ~10W
5.Subjective obtained GPU power consumption = ~ 173 Watts
Measured power consumption two cards in SLI

1.System in IDLE = 155W
2.System Wattage with GPU in FULL Stress = 473W
3.Difference (GPU load) = 318W
4.Add average IDLE wattage ~20W
5.Subjective obtained GPU power consumption = ~ 338 Watts
