That's a "TFX" form factor PSU. They max out around 350W but more commonly 300W. If you get a good quality unit, that's still plenty for a GPU that doesn't require external power (if that's your intent).

You really can't upgrade proprietary power supplies like that. Sff computers are not intended to be upgraded.
