The title says it all. i am buying a g1 sniper a88x amd motherboard and want the hd 7770 and on the radeon's specification page it says PCB should be ATX. Tell me if it will work and explain PCB.
ATX is the size of the motherboard. ATX is the most common. Theres also micro ATX, mini ITX and XL-ATX. The only reason they might be asking for this is so that it ensures your card will fit in your case. As in, the card will be shorter than a ATX boards width so is guaranteed to fit.
Anyway, ignore that. It will work, just use the X16 Pci-e slot.
