My video card (xfx geforce 880gt) requires a power supply to be connected directly to the card. However, my motherboard also has a power connection called Auxilliary Power for Graphics (PWR3). It is also called "AUX PEX Power connector" on the mobo diagram.
Long story short (which I shall make longer if this is not the solution) is it necessary that I have power supplied to the auxilliary power for graphics connector on the motherboard, in order for me to get video?
I have assembled this computer twice already and this is the only thing I can think of that could be the problem, other than a dead video card.
Reason I'm asking in this forum instead of just doing it is that I am at work and I'd like to know out of curiosity before I leave.
Mobo is XFX nForce 860i LT
Video Card is XFX GeForce 8800 GT
