I want to upgrade the power supply on the Dell Inspiron 560, so it can support a better graphics card than what the GMA it has built in. But I am afraid, from what I have heard, Dell motherboards do not support other power supplies as they are different on some things.
I have a link to the specs given by Dell on the power supply and pc overall.
dell PCs and mobo will take any standard PSU, ive installed plenty of after market units in DELLS. if you are looking for a budget unit, check out the corsair CX line and the antec neo eco line. they are solid units for your dollar. sites like jonny guru, techpowerup, and hardware secrets all do an excellent job reviewing PSU if you want to look at other units.
