Motherboard won't detect new GPU. Why?

[Gammio]

I have a 880GM-USB3 rev 3.1 motherboard, and I just got a 560 Ti EVGA GPU. I jammed the thing in there (It was a tight fit,), and even though the fan spins and everything, my computer won't detect the fact that there's even a card inserted!

The thing I had before was a 520 EVGA card, and it read that fine, and all of my drivers are up to date, so I'm really confused

Plz help!

You may need to configure System BIOS to detect your PCIe graphics adapter. Have a look through your settings and see if you have options for video priorities.

Nope, turns out I'm just a retard. You know those extra cables, the ones that look like they go to a power supply, the ones that CAME IN THE BOX, yeah, turns out I needed to use those.

Nevermind! Sorry. Thanks anyway though
