what about this post then?

Didn't think of that, the mobo & everything but the gpu was powered from one PSU, Just the 2 x pci-e plugs running off the second PSU. I'll throw in the 2nd lightning & just test the single psu with 2 x 680, I'm running a 2600k right now but should be similar power draw to a 3770k for a whole system test.
Edit: It was a bit of a shocker, went to try with 2600k at 4.5Ghz, 2 x 680L at 1400/1752, +100mV. Got a full rig shutdown in gt1, 1080W showing on the meter. Tried cards completely stock volts & clocks (ln2 bios), pulls 756w from the wall.
OCed +100 on the core & +499 mem (1307/1752), no added volts, 820w from the wall. Added 50mV with same clock, 900w from the wall.
Only extras attached to the mobo are 2 case fans & 1 ssd. Cooling is externally powered."
so overclocking them at maximum will actuallly require more then 850w ?
