[Legend21]

Hello people,

I need some help.
I was wondering if anyone would know
if i can use my 750W PSU for my 5970 and 7970 cards.

My PC setup:

Motherboard AM3+ GIGABYTE
Athlon II 270
HDD
4GB DDR3

I have no floppydisk or dvd-rom drive.

Thank you for reading and hopefully someone can help me,

Bye

If your PSU is built by any reputable manufacturer then 750W is more than enough for those cards.

It depends. If +12V max output is greater than 700W,and you're not going to overclock,it will be enough.

ok tnc for all you help.
its says 12V+ = 748W max.

the maximum peak 820W

If i put my agression to high is that still save without overclocking the cards?
