The rear I/O on the GPU should be facing out the back of the chassis.
Take your graphics card out of the anti-static bag and line it up with the slots we just opened up. The rear I/O on the GPU should be facing out the back of the chassis. Once the gold contacts on your GPU make are touching the PCIe slot, gently push it into place until you hear a click. Then use the same screws we removed from the PCIe slot cover to secure the GPU into place.
