Wow, that's 55W AC more than mine requires stock P95 loaded and yet you have basically a very near exact config to mine, though I have 1 more SATAII HD + Zalman fanmate + extra 120mm fan.

When I undervolt mine to near exact volts as yours, it requires 143W AC fully loaded at stock speeds.

The PSU is 83% efficient from 151W-213W AC, 81% efficient from 110W-148W AC and 78% efficient 87W-110W AC.
