How many Watts of electricity will I be using with:

I5 2500k

GTX560TI

8gb 1600 of ram

Windows 7

ASUS P8P67-M Mobo

800 Watt PSU

1TB hard drive

on 1680x1850 resolution monitor



I am thinking around 500...Right?|||http://www.thermaltake.outervision.com/ You can always try a PSU calculator as you've listed your components but you havent listed peripheral devices and cooling fans etc they also add to you computers power consumption|||Idling, with monitor on but asleep, I would expect around 100-150W... cranking with a high processor and graphics demand application, you're probably close to 500-550W|||You have more than enough power.|||i think so..

but i like ur hardware!
