CPU : intel i7-4500U
I have two pcie graphics cards
One is ATI FireMV 2250 (native x1)
The other is SAPPHIRE HD7750 (native x16)
But on sharkbay-ult, it only works on ATI FireMV 2250
I use a x16 to x1 connector on SAPPHIRE HD7750 to fit the slot on motherboard
But it can't work when power on the machine
What's the limitations of graphics card on this platform? Power supply? But I'm already use a ATX Power of 600W
Or other limitations on ult-chipset?
