    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.
    Hmm I have a fanmate connected to the cpu fan two amd stock cooler fans for pwm and chipset cooling and one additional 12cm fan. Should not make more than 15W difference. I'll try it with two sata disc and without the Scsi and audio stuff for better comparison.

    EDIT: Now with mobo/ram/cpu one additional 8cm fan and two 500GB sata hd's Maxtor 7H500F0 and WD WD500SYS Raid Edition and one LG IDE DVD-Writer (forgott to mention before). Temps(SG)/Fanspeed CPU 42°C/1240RPM PWM 42°C/2200RPM at 22°C ambient in open case.

    Idle:
    124.5W AC / 99.5W DC (79.9%)

    Load:
    198W AC / 159W DC (81.5%)

    Compared to 143W AC/111.5W DC so yeah 50-55W difference. On the M3A the system required 172W AC / 140W DC on a setup with an HD2400pro (- 10-15W difference) just one ide hd ( - 2-5 W), no dvd drive ( - 2-5 W) and no extra fan (- 2-5W). Add 15-30W AC and it's equivalent to the saphhire/dfi mobo. Used an 9500 at 2.2GHz 1.18V cpu vid/1.075 nb vid here.
