So in my Asus desktop pc, I have a motherboard that is an Asus h81m-k/k31ade/dp motherboard. It does not have a separate box power supply instead it has direct dc power from the household plug. I'm looking to do some light game and want to add a gpu. The motherboard has a pcie slot so it mean it can support a gpu. I just dont know if the incoming power will be enough.
these are pictures of the mobo and power.
