What is the best video card a pegatron m2n78-la could run?

[Timmyey]

Hi all, I'm thinking of upgrading from an ATI Radeon 4670 to an ASUS EAH6770 DC SL/2DI/1GD5 HD6770. The only thing that I'm concerned about is that my motherboard - Pegatron m2n78-la by ASUS isn't powerful enough, so I would like to know if I should buy the 6770 or not. Thanks in advance!

If this is your motherboard: http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c01635734#N291
...you should be able to use any PCIex16 graphic card. The card will be limited to PCIe version 1 speed, but that won't be an issue. The more important issue is how large is your power supply. The HD 6770 requires 108W at max. That relates to 9A on the +12V rail (108/12).

What size PSU do you have? Does it have a 6 pin PCIe power cable?
