Well thanks to this little guy I bought, I now know.
http://www.newegg.com/Product/Product.aspx?Item=N82E16882715001Computer specs:
E6400 2.13ghz stock
4gb 667mhz ddr2
2x250gb Maxtor's in RAID 0
1x500gb Seagate
Plextor DVD-RW
SB X-FI Fatality
EVGA Geforce 8800 GTS 640mb
1 USB expansion card
3.5" Memory card reader
600W Xclio Great Power PSU
2 x 120mm | 2 x 80mm fans
Idle: 200-205 Watts
Gaming Load* (50-70% CPU load, 70% RAM load): 260 Watts max
Prime 95: 230 watts
*Two readings were taken. 1 x AH 1600x1050, 1024mb textures, 4x AA. 1 x COH performance text, 1600x1050, 4x AA, almost all settings on high.
Overall, I was surprised at how low my numbers were. I was figuring 250 idle and 350+ on load. Now for the whole setup...I plan on testing that as well. This will include my 20" and 17" LCD's, Laser printer, scanner, 4.1 speakers. 1 APC 1400 UPS, 2 Belkin 700 UPS's. 1 IBM 500mhz Aptiva, DSL modem and router.
I'm interested to see what my whole setup is running in electricity. For the last couple months I've been shutting down my computer while I'm not home or I'm sleeping. I used to be a guy that left it on 24/7. The Aptiva computer I have runs 24/7 as it is serving as a linux firewall (IPCop).
Other things I've used my Kill A Watt on:
Wife's $90 hair dryer (yeah... I know
): 1600 watts on high
27" TV, Wii, DVD player, stereo (TV on, others standby/off): 80 watts.
Lamp with 13 watt CFL bulb: 22 watts
