Powercolor is the first AIB partner to announce a passively cooled HD 4650 card, the Powercolor HD 4650 SCS3. The card works at reference clocks and comes with 512MB of DDR2 memory.

This card is based on ATI's RV730Pro GPU, which works at 600MHz. This passive version of the card will come with 512MB of DDR2 memory clocked at 500MHz (1,000MHz) and paired up with a 128-bit memory interface.

As the entire HD 4600 series, this card also supports DirectX 10.1, PCI-Express 2.0, ATI's CrossfireX and comes with HDMI support.

Unfortunately, this card isn't yet listed; but we will surely keep an eye out for this one, and this is how it looks.
