Anyone managed to push theirs past 225?
Every time I 250, it jumps up to 1275W in, but beeps constantly and eventually drops back down in 5-10 seconds.

Edit: At 225M I get 1153GH/s using 1148W using an EVGA 1300W G2 on 115V. It will probably be a little better on 240V, but I don't have per-outlet metering on my PDU and I wanted to get power measurements using my KillAWatt.
