EVGA POWER SUPPLY

I have an EVGA NEX 650w and its spot on, I've looked at the techpowerup bench tests for it and stuff and they all look pretty solid good quality PSUs
 
I'm pretty sure an AX860 should have no problem with 2 770's or 2 780's, even overclocked. What else are you running along side it?

Edit: The Maths.

770 and 780 both top out around 250 watts, about 21 amps, so 42 amps on the 12v for 2. Your AX860 has a whopping 71 amps on the 12v rail.

Oops and it's the Asus maximus vi extreme mobo and just about to install the swiftech h320
 
To be honest, I would consider running all that on my 750W XFX. You certainly don't need to worry! :)
 
I've read that at peak the evga 780 classified with require 430 watts so if I had both cards on oc settings and say running an intensive benchmark I might hit my limit
 
The EVGA website only says 250 watts.

Not sure I can link because they sell on their site, but it says "Total Power Draw : 250 Watts"

I'd have though if they pulled 430 watts it might cause a few problems, as that's 35 amps, which is a lot to be pulling through the cables and connectors.
 
That's power consumption for the whole rig not just the GPU :)

So if you took their 440 watt rig and added a second 250 watt card you're still only at 690 watts. And that's not even taking into account the efficiency of the PSU.

If you assume 90% efficiency, that's 400 watts. 150 watts for the CPU, drives and memory, e.t.c and 250 watts for the card.

I'm happy with that then no need to sell my ax860 :)
