Does anyone know what the actual power draw of a system with a GTX 1070 or GTX 1080 would be? The calculators I read online are apparently wildly inaccurate, as are the manufacture recommendations.

I have an i5 3570k @ 4.2ghz + 8GB RAM + 1 HDD + 2 SSDs for reference.


I just want to make sure that a 550w PSU isn't 'on the edge' for a 1070/1080.


Cheers.
 
The manufacturers' recommend a 600W PSU for a 1080, because they're basing it on budget units. It's a case of CYA (google that acronym) in case someone damages their PC. A good 550W PSU is ample for any single graphics card setup. The 1080 is more power effcient than a 980Ti. I used to run a 4670K @ 4.2GHz with a 980Ti using a Seasonic 520W PSU. A 1070 draws less power than a 1080.

The EVGA G2 series are made by superflower, who are a very good PSU OEM. If it was a "budget" 550W PSU, then I'd be very cautious, but a decent 550W is more than enough.
 
Easily, in fact a 550w unit is what we normally recommend on here for a single card setup. Just to give you a idea of actual power consumption, the pc in my siggy along with several fans, temp sensors, 2x fan controllers and all the watercooling stuff hit a max of just under 300w at the wall when benching with the gpu heavily overclocked. This is with the cpu and memory overclocked as well. Normal gaming use is no more than 252w at the wall.
