The 7770 HD requires a 6 Pin PCI-E connect which I doubt your 300W PSU has.

The Card Requires-

Power Supply : 450W (or greater) power supply with one 75W 6-pin PCI Express power connector. Certified power supplies are recommended.

Lucky for you, your case will accommodate a new Power Supply (I would recommend Antec, Corsair or Seasonsic)
