6970 and PSU with motherboard

[waterhook]

Hello, I am in need of some expertise. I was planning on upgrading my computer with a new GFX. But i'm unsure if the PSU I have selected is compatible with everything.

CPU-z says that I have a Gigabyte GA-770TA-UD3 motherboard. Does the ATI 6970 (pci-e 2.1) support this motherboard with pci-e 1.0?

The psu I have selected is Arctic fusion 550R. Is everything compatible? It would be nice to know if everything works together before I spend any money on it.

If you want to objectively, accurately and scientifically determine what PSU power is required for your Vid card and PC in both watts and 12v rail amps., the forum Utility link below will show you how easy it is to calculate this information and objectively determine which PSUs are quality built, reliable PSUs that can meet your needs. Be advised that the available 12v rail amps. is just as important as the total PSU wattage. You need both to be correct.

that is all technically compatible but i would be weary of that psu-gpu combo. the psu is the minimum amd recommends for the 697o and it is not a top of the line brand. i would shoot for a decent psu in the 650watt range. THis coolmax would work, its still not an excelent brand but i have used them before and they lasted well. http://www.newegg.com/Product/Product.aspx?Item=N82E16817159089
