I have an el1630g and I wanted to install a VGA 210 G card. I disabled the integrated card hit the f2 and enabled the PCI saved and exit. still got a flash of green then just black so I'm thinking the power supply it has a 210w. so looked at what some other people was posting and came across this 480W Upgrade Power supply for HP Pavilion P6000 same wire and plug set up but it will not fit in my tower. So I'm wondering can I leave it outside of the tower plug everything in and it still works. Or is there some reason that I can not do that.
