High-power cards that draw only from the PCIe bus

    One company has a Radeon 6850 that has the same specifications as AMD's reference design yet lacks any 6-pin power connectors; it draws all the power it needs from the PCIe bus. I know I'm being paranoid, but does this design increase the chances of the 24-pin ATX power connector having a meltdown? I'm referring to the issue where two pins on the connector would overheat and cause the surrounding plastic to melt because of too much power draw (it seems to usually happen on overclocked and/or SLI/CrossFire setups).

    (Sorry if this belongs in the motherboard or PSU section.)

    PCI-E graphics card can draw up to 75W maximum from the bus 3.3V and 12V power.

    Doesn't PCIe 2.1 allot for 150W, though?

    No, the pcie bus is still only 75w.

    Well then. :confused:

    If anyone's still curious, the card is the Afox AF6850-1024D5S1. What's odd is that it has an area on the PCB clearly intended for a 6-pin power connector.
