Fall is in the air!

Tonight is the first night in a good while we've gotten a little chill in the air around here.
I recently got my kill-A-Watt device back and decided to run some quick tests on power consumption and temps.

Setup (ALL AIR!):
Q9550 @ 4GHz 1.256v
TRUE w/ 115CFM Panaflo
P45 Maximum II Formula
4x1GB DDR2 1132MHz 5-5-5-15 2.15v
GTX280 1.175v w/ AC Extreme 729MHz-GPU | 1458MHz-Shader | 1260MHz-RAM
300GB VR
PC P&C 750W
Thermaltake Armor w/ excellent airflow

I opened the windows in this room, and this meat thermometer is reading 72*F right now.
It was at 73*F at the beginning of the tests.
In the summer I run the A/C at 77*F, and this room always heats up more b/c of the PC's and the afternoon sun, so this is a nice change of pace.
My PC loves the constant supply of fresh air!
She's a little dusty, but the CPU and GPU still never get over 50*C under full load.

Idle at the desktop she pulls 165W from the wall, and temps are 26*C on the hottest CPU core and 29*C on the GPU.

In the pic below I'm running P95-small fft.
The ambient is 73*F, and it's pulling 304W from the wall.

In this SS I'm running Furmark at 1024x768 16xAA.
Ambient dropped to 72*C.
The VRM's get a little hot, but everything else is nice and cool.
Kill-A-Watt reads 410W.

In this one both P95 and Furmark are double-teaming for 516W from the wall.
Ambient still stable at 72*C.
Temps on the VRMs have climbed a bit, but stabilized.
Furmark really cooks the VRMs w/ all the extra current it draws!

If we assume 83% efficiency from the PSU here is an estimate on what the PSU is delivering to the PC.
