How many watts will this need?

post #1 of 9
Thread Starter 
Finally made up my mind and got gpus for my new build

How many watts will 3x6970s need?
As i understand they consume significantly more when overclocked, and i plan on overclocking all three to 1ghz

I'm sure the psu i have is enough... but don't feel like trying to overwork it since i'll be keeping this psu for a while.

850W would be comfortable, but your 1200W is more than enough!

wow... i had a ax850 before this... i thought that the power consumption of 6970s were comparable to 580s when overclocked... didn't know that 850w would have been sufficient

AX850 would have been sufficient but you'd have very little headroom.

A lot of things are power efficient. I'm gonna run 4gb ram e5300 and 4870 on a 500w basiq and still got breathing room. You want amps more than you want watts because wattage rating is based on max output. You gotta think, A kilowatt Is 30% of my apartment usage. May be a power house but not a power hog. It takes a good amount yes, but not as much as you think. Side note, I've ran an e7200 @4GHZ 1.43v with oc'd 8800GT, 3 SATA HD's, two DVD drives, a sound card, usb devices, and 4GB RAM 1066 *1.9v 4-3-4-12. On a 250 cheap random PIII having computer's powersupply, oh ya it got hot but, but it did stress test for 8 hours before it went unstable. Why? 45nm CPU and I think GPU's are 32nm or 55nm or something.
