But if I disconnect my fans hdd and burner it goes down to 74degrees. Do I need a bigger psu?
@onthemour, if u disconnect them, how do u run them? u mean u power them with a different psu?
I know this is enough volts. I am asking about current ie amperage. The 7970 draws more than 30 at stock and 20 to40% more if oced. Which puts it at close to 40.
If u're talking about current flow(ampere), then 7970 doesnt draw 30 at stock. It draws from 210 to 270 watt maximum(this info varies,strangely.. tom's hardware says 250 watt and guru3d says 210 watt TDP for this card).. So that makes the current 270/12=22.5A maximum...(As u probably know Power=current * voltage)
Remember modern graphics cards and processors take power from the 12V rail.. Thats why divided by 12.
And ur processor TDP is 95 watt, according to Intel...
So U said ur psu is 63 amp.. Do u mean it has 63A over the 12V rail alone? If so, then surely ur psu has enough power.
