So I just finished building my PC. Things seem to have gone well, in general, but my GPU is not showing up in my device manager. I tried to install the driver but the install would not go through correctly (apparently because the driver can only be installed if the computer is aware of the card plugged into the motherboard). I have an Asus Radeon R9270X (http://www.asus.com/Graphics_Cards/R9270XDC2T2GD5/) and a Gigabyte H97-D3H (http://www.gigabyte.com/products/product-page.aspx?pid=...). My suspicion is that I have something plugged in incorrectly or not at all. In particular, I'm worried that it's not being powered correctly. The GPU has two jacks on the side of it facing out at you when you open up the computer. Both of these jacks have a red light when there's nothing plugged into it but a green light then when there is something plugged into it. Should these be hooked into the PSU directly? What sort of wire do I need to get to do that? Does only one of them get plugged into the PSU and the other get plugged somewhere else? I wish I could have answered this question on my own but unfortunately the card comes with zero instructions and the website offers zero support; nor can I find anyone else who has had the same problem (so I assume it's something easy and obvious).

If anyone could give me advice on exactly what wire configuration I should have in order to get this guy up and running, it'd be greatly apprecaited.

Your GPU needs two 6-pin power cables run directly from the PSU to the GPU. Usually you get the cables with the PSU. What kind of PSU do you have?

Edit: According to the Asus website, you should have gotten two cables with the card. The short one with the flat connector is for connecting to another card for Crossfire. It connects to the flat bayonet contact on the same side as the two power connection ports, but at the opposite end. The other cable should have six-pin connectors. That's one of the cables you'll need to power it. Your PSU should have one that looks just like it, or it may have an 6+2 pin connector, which serves the same function only six of the pins will be in a single block, and the other two will be on a little pigtail. If you have the 6+2, just plug in the 6-pin part and tuck the pigtail out of the way.

500W on a good PSU will do the job according to Guru3D and a couple of other reviews - 700W for crossfire, but that's not the case here.

The only wire that the card came with is a 6 pin connector that spreads into two different molex connectors. I assumed it was for Crossfire but I didn't really know. Is there something I should be doing with this wire? Or do I have to go buy another wire?

okay, so i think i found the plug for the job. both lights are green now indicating that there's something being plugged into both the 6 pin holes. however, when i start my computer with them plugged in, i get no display (so i can't even see BIOS) and when i try to plug it in after it's booted, i still can't get the driver to install. this has been such a pain. do you have any more suggestions?

Haha - thanks much! I was just experimenting with that trying to figure out how to put a screenshot up in another thread. I knew there was a guide on it somewhere but was too stubborn to look it up.
