Anyone know if it runs the card? It has 28A on 12V rail.

My old PSU 450watts peak is 18A on 12V rail and I think it wont support the card.

550W is the minimum.

It doesn't have enough PCIe connectors and has a very small number of peripheral connectors, so if you did use peripheral to PCIe adapters you wouldn't have many left for fans/optical drives, etc. So I'm going to say no.

550 watts is the recommended minimum.

Barely - maybe. A 6870 will pull about 15 amps. Depending on the CPU, that's 8 - 10 amps. Figure 2 - 3 amps for a hard drive, an optical, and two or three fans.

With a "typical" system you would be running the 12 volt rail at over 90% of capacity. Not a good idea.

Get a larger (500 - 550 watt) PSU.
