For anyone interested, here's the power consumption for my system. A wattmeter was used to observe power consumption in watts which was then adjusted for PSU efficiency to obtain the power delivered to the components. Power supply is 650W and 90% efficiency rated at 230VAC.
Test system
PSU .... Seasonic X-650
Mobo ... Asus P6T SE
CPU .... Intel i7 920 @ 3.2GHz, 1.2V. HT on. Idle @ 1.92GHz. Load @ 3.36GHz. (TDP = 125W, +15% OC)
RAM .... 3x2GB DDR3 1600MHz 1.65V
GPU .... Gigabyte 560 Ti SOC @ 950MHz @ 0.95V. (TDP = 170W, +15% OC over stock 560 Ti)
Audio .. Asus Xonar DX PCI-e
SSD .... OCZ Vertex 2E 120GB
HDD1 ... WD Caviar Green 1TB
HDD2 ... Samsung F4EG 2TB
ODD .... LG DVD-RW
Fans ... 3x120mm 700RPM and 1x140mm 500RPM controlled by Aerocool Touch-1000. CPU-fan 400-1300RPM.
Test scenarios: idle, 1080p .mkv playback, 3DMark Vantage, Furmark, Unigine Heaven 2.5, Prime95, simultaneous Prime95 and Furmark, and simultaneous Prime95 and Heaven 2.5. Results are given in AC power (wall reading) and DC power (PSU output, or AC x 0.9). So it's going to be AC/DC from now on
Idle
AC = 128W
DC = 115W or 18% load
1080p .mkv playback (VLC)
AC = 155W
DC = 140W or 22% load
Prime95 (download)
In-place large FFTs stress test. CPU max power consumption.
AC = 250W
DC = 225W or 35% load
Unigine Heaven 2.5 (download)
1080p default settings.
AC = 290W (average); 307W (max. observed)
DC = 261W or 40% load; 276W or 43% load
3DMark Vantage (download)
Performance preset, Jane Nash benchmark.
AC = 305W (average); 314W (max. observed)
DC = 275W or 42% load; 283W or 43% load
Battlefield 3 Beta
Ultra Preset, Metro map gameplay. Realistic gaming load scenario.
AC = 330W (average); 340W (max. observed)
DC = 297W or 46% load; 306W or 47% load
Furmark 1.9.1 (download)
1080p full screen. GPU max power consumption.
AC = 375W (GPU fan @ 50%); 380W (GPU fan @ 100%)
DC = 338W or 52% load; 342W or 53% load
Prime95 + Unigine Heaven
Highest practical system power consumption.
AC = 400W (average); 404W (max. observed)
DC = 360W or 55% load; 364W or 56% load
Prime95 + Furmark
Highest theoretical system power consumption.
AC = 480W
DC = 432W or 66% load
That's that. Comment, share your own results. Or just use as a reference when choosing a PSU for a similarly power hungry system. It would be awesome if this thread expanded into a database of power consumption for various systems, but I'm mainly creating this post so I can link it to my sig
