RE: 35W Limit on PCIe x16 slot: Optiplex 790 SFF
Did some digging. According to this it would like to have 20A. I understand that these requirements are little over what is required in reality, but how do you know the GPU is getting all the power it needs exactly? Would not it take all it could get @ 100% and the figure you gave would either be a) what it needs or b) what the slot is able to deliver (it could require more for full function)? How do you know which is the case?
