Will the wrong kind of power supply kill the motherboard and every thing connected to it ....or just the motherboard ?
I wanted to upgrade my Dell Optiplex GX280 (only 6 months old) power supply from the 305 watt to a 400watt, so I can run a 7800 Gt graphics card for high end games. Well I bought one on ebay...when it arrived, the main connection to the mobo, don't know what it's called, only that it is about a inch and a half in width that snaps on to the mobo. Well it wasn't the same size as the original (about 4 pins shorter)...but I forced it on any way, because the seller said it was compatible with the GX280. When I tried to power up ....nothing works. I re-installed the original power supply...and still nothing works. So now I'm wondering if the memory sticks, HDD, and other stuff connected to the mobo are "fried" (dead) ...or is it just the motherboard itself that needs to be replaced. Or will I need to just buy a whole new desktop PC...and make the Optiplex just a bad memory and learning experience?
Any help or advice will be appreciated ....write : firstname.lastname@example.org
