I just picked up a used Dell Optiplex GX260. The guy that I bought it from put in a stick of ram and plugged it up to his power supply to show me that it would boot up. He said that I would have to buy a hard drive, ram, and new power supply since he could not get it to power up with the one inside of it. Anyway, I would like to run out and purchase a new power supply this evening but want to make sure that any standard ATX power supply would work with this PC.
It currently has: Dell Model# HP-P2507FW, 250Watt power supply, 20 pin and 4 pin.
Also, if I can purchase a regular power supply (not dell brand), will the pc power up without memory and HD so that I at least know that the PS works?
