Do a Google search for the specs of your PC eventually you should fine the power supple wattage. Most prebuilt PC seems to come with a 300w PSU which is generally enough for the Radeon HD 7750. At least a 350w PSU would be required for the Radeon HD 7770.

I'd also suggest a 7750, just because you have a low end PSU. It doesn't need the power supply connected to it. The 7750 is definitely a great upgrade from onboard graphics.
