Graphics Card Not detected

So, I just put together a computer for the first time, and almost everything works well, except for the graphics card. When I turn on the computer, the GPU fans will spin for a moment, and then stop before the computer boots. I try to install the driver for it, and it says no compatible hardware connected. By adjusting it a bit, i can get it so that the GPU fans will spin, but the computer won't turn on. Any help with this is greatly appreciated.

Your powersupply is crap (and underpowered anyway). Replace it ASAP

Do you have the PCI-E connector plugged into the card?

On the mb make sure the four or eight pin power plug is connected near the CPU. On the gpu make sure both six pin plugs are filled.

Yeah, I know its crap, but it seems to be powering everything. It came with the case. I'll probably replace it at some point though. I used the calculator and it should be enough to power everything.

All power plugs are connected, and the gpu only has a single six pin plug.

If the GPU fans are spinning, then the monitor should be plugged into that and not the motherboard.

The computer won't even turn on when I get the GPU fans spinning. The led flashes and the cpu fan barely starts to spin, and thats it.

Sounds like its the garbage PSU at fault then.

Hmm, it's possible. since the symptoms are the same both ways, either gpu fans run, and cpu fan does for just a half of second, while when the computer does boot, the gpu fans only spin for a few seconds.

The one you linked is coolmax (another bad brand) and has 37% 1/5 bad reviews.
The one I linked is Seasonic (a good brand) and only has 9% 1/5 reviews.
