I have a Gigabyte GA-990FXA-UD5 Motherboard and when fully populated it has 3 PCI Express 8x slots, 2 x4 slots and 1 x1 slot.

I was wondering if i would be able to fully populate this board with 6 cards with extenders ?

I have a Strider 1500w powering it, I'm just not sure if the motherboard will handle it.
