Asus Z87 Pro Motherboard + Nvidia GTX 780 TI GPU not compatible?

First computer build and I think I have a huge problem: I cannot put the graphics card in the highest slot of the motherboard below my CPU cooler because it's too long. It bumps into the USB 3.0 attachment.

Am I screwed or is it ok to put it in the next slot down?

I think you are fine with the ASUS Pro, it has only 2 * 3.0 slots, if the first is not occupied it lets all 16 lanes go to the 2nd. But don't use the 3rd *16 slot because it is 2.0 running at x4 I think.

I would post this question at the ASUS forum to make sure. What exactly is it hitting?

Where the USB 3.0 ties into the motherboard. It's like 1/4" too big or less but still won't do it. I might be able to "squish it" with that plug but that seems dumb.

If I can get full benefit on the second slot then i'm less worried but I am just a normal guy trying to build this so I don't have expertise on what I Need to even look up to make sure it works hehe. I will ask on the Asus forum though.

I had the power supply plugged upside down until I read an article. I guess it can work the other way but it wasn't the "normal" so i'm struggling on the last piecing together here.

I looked at an image of that MB and it looks like the USB 3 connector is offset enough to be out of the way (the one by the memory), is it the back plate that is hitting it?

Also checked the specs on the PCIe slots, it may get all 16 lanes in the 2nd slot. I would try it there and check. That is a really GREAT rig you have put together, it ought to rock!

Did you get a solution? I ask because I was looking at the same setup and was planning on sli in a couple of years time, but if you can't use the top slot and will lose performance on the third slot I may have to look at a different mobo.

This is the first time I have ever heard of this kind of problem, I'm still not perfectly clear on what is going on?

From what I can gather, the gpu is too big to fit onto the mobo in the first slot as it's too close to the USB connection above to take the depth of card.

Yes that is what I gather also, but he could not be the first guy to plug in an AUSU 780Ti into an ASUS Pro MB? Or maybe he is :(  The only thing I can figure is the card is wider on the back side than most cards......

His parts list is showing a card with an NV stock cooler on it, the silver one. It looks like it does not even have a back plate, 10.8" long, not that long. I don't get it, something is not adding up

Sorry to cry wolf but it does fit. It's tight though but I just had to take the wires through a different grommet hole to get them to not be hitting it when installed. I don't know how to explain my foolishness other than a rookie mistake. Basically the wires come in the case in the grommet hole where the card sticks out in front of. It just didn't occur to me to just pull them back through to the next one up. I'll feel dumb the rest of the week now though.
