750 or 850 PSU? OC'd 5820k&1070
OC'd 5820k to 4.6Ghz 1.32v; 1070 110% power consumption at 2Ghz. Both draw 300-350 watts and I'm not confident with my 750w PSU at 90%. Should I switch to EVGA supernova G2 850 from the 750w model?
His system power, with maximum load, will be around 550W.
1) Running the system without a GPU at OC to 4.6GHz will consume about 350W.
2) GTX1070's maximum OC is likely around 200W.
*I think your load will never exceed 75% of the PSU. No problem. This is just a worst-case situation. You're unlikely to run at full CPU usage while the GPU handles the same tasks.
Typical gaming demands are close to 50%.
Your error lies in the GTX1070 calculation. I don't know where you found that. Maybe it was the total system power for a Skylake build under stress. (Some reviews show total GPU draw, others show overall system draw.)
The 750w EVGA G2 is more than sufficient and capable for those components.
