light bill?

[successfulerror]

i have a 500 PSU, i have it on about 6 hours a day so 186 hours a month, how much should my light bill go up? X2?

not even close,.. a fridge uses about the 10 fold of the power a pc would use.. i think it would go up by 5% max or so besides... i really doubt your pc uses the 500W your PSU can deliver ( if no 500W is drained from the PSU, it wont deliver 500W either )
