You didn't say what other hardware is also getting power from the 350W PSU.
It's well below the 450W PSU recommended by Sapphire for it's 4770 cards.
Even more of a concern is the 9A +12V rail. Most 'average' 350 PSUs will have 19A or better +12V rating.
I've seen $10 budget 250W PSUs with more than 9A.

If that 9A is accurate and you're powering a normal PC set up I'd say you probably can't run the 4770.

Here is the data panel off a $10 PSU. It's claiming 29A of +12V (348 divided by 12)

The official ATI recommendation for a pc system with one ATI Radeon HD 4770 video card is 450 watts. That's 50 watts less than what I usually recommend because it is an energy efficient card.
