Pci1 mobo running pci 2 card: power supply Tags: Graphics Cards Power Supplies PCI Graphics Last response: November 26, 2012 11:50 PM in Graphics & Displays Share TreetopFlyer November 26, 2012 11:27:52 PM Hello, I have a pci 1 mobo that I want to put a pci 2 card in. it used to have a pci 1 card in it. will i need a power supply upgrade (currently a 350w)? Im guessing that everything runs at the least common denominator (pci 1) and that i would NOT need to get a new power supply, but figured id ask just in case.
