I need to know if I'm able to upgrade the video card and power supply in this ridiculous Acer Aspire AX1420G-U5832 that I recently acquired. I don't care whether it is external power supply or internal, I just can't seem to find one. I'm looking to upgrade to a video card that requires 350+ watts of power. I have the PCIE 2 x16 slot. I know I can insert a card. I just need the power to run it. CAN SOMEONE PLEASE ASSIST ME???
