SHould I run 1 1000 watt PSU or 3 400 Watt PSU for my 3 7970 and how much watts of a power supply do i need to run 3 7970 gpu's

Are you going to overclock much? Cause 800-900 Watt PSU should be good enough... its way cheaper..

I would advice to buy 1000 Watt PSU but it is about 30-40$ more costly then if you buy 2 500 watt PSU. Worth the trouble and problems...

1 PSU is better just make sure you get a good quality one....

run 1 psu, differences in voltages from multiple PSU's can cause power feedback, which is very very bad

1000 Watt PSU would be better... Multiple PSU is just too messy....
