In a way I hope the answer is this simple but there's a part of me that hopes not because it means I have overlooked an obvious step that was clearly stated in my motherboard manual.

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

Good rule of thumb, is that if there's a power connector on any piece of hardware, you put a power plug that matches it in.

So to answer your question, yes you should have a power plug plugged into it.

*EDIT* -- That power plug is mainly used to power the SLi when two video cards are attached, but I only have one Video Card now (used to have two 7800GT's) and haven't had a problem.

Yes I was hoping/fearing that would be the case.

Thanks for your quick reply.

I will post back with results when I get home.

Well, it didn't work. The plot thickens. I'm going to make a new post that will include all of the relevant information.

Thanks again for the help.
