in a word: no.

ATI Radeon™ HD 4600 Series System Requirements:

400 Watt or greater power supply (550 Watt for ATI CrossFireX™ technology in dual mode) is recommended

+1 for providing a source. –  TFM Aug 29 '09 at 2:26

It probably will not handle any current video card. That's not to say that maybe you couldn't find an older card that would work with your psu, perhaps an older pci. I doubt it will have the performance you are looking for though. Power supplies are fairly inexpensive so upgrading it usually doesn't kill your wallet and it's a good place to plan for the future also. The more steady power you have the better. Hope that helps.

Contrary to what most others say, I'd say this will work fine. I have a 4670 with a 300 watt PSU [I'm pretty sure that's what it is anyway :p] and it works fine. The 4670 doesn't need a PCIE power connector, it uses solely what it gets from the PCIE port.

and what about performance? can you provide benchmarks for your machine? –  Mahmoud Hossam Aug 29 '09 at 5:27

It's certainly better to have a slightly overrated power supply rather than an underrated one, as the latter could result in an blown PSU or even damaged components.

4670 is rated for only 59 watts max. It's a very efficient card.
