1 x 4-pin P4 Connector
3 x Molex IDE Connector
1 x Floppy Connector
1 x SATA Connector
Max. Output Power: 250 W
The bad news: you'll have a hard time finding even a low-end graphics card that will (officially) require less than a 350 or 400w power supply.
The good news is that it looks like the PSU is a standard ATX one, so replacing it would be straightforward. (The 140mm length is shorter than some, but I doubt that'll be an issue.)
The further bad news is that good power supplies aren't free. I suggest at least a 500W PSU from one of the trusted makers (Seasonic, Corsair, and Antec, although there are others).
