Suffice to say this dumb question is at my own risk, so here goes...
Have an Acer relatively new and great machine, but graphics are a little underpowered. Bought a card and attempted an install only to find the power supply is a bit proprietary. The power runs through the mother board to peripherals and doesn't have excess supply for graphics card.
In the face of this odd duck, here is question: Bought a second power supply before I realized the on board supply was so proprietary. How can I power the card with second power supply, external to the pc chassis?
I attempted this (yes, as I stated; this is at my own risk) but the power supply didn't turn on. Am assuming that it is looking for a signal from the mother board but it's not connected to one. So I can get power to card using 2nd supply, but need to know how to trigger second supply to power up?
2nd power supply is a Cooler Master GXII 650 watt.
