So does that mean that the power consumption is only 30W then, or is it more? From the FAQ at ATI it says:
Q2: Does the RADEON™ 9700 PRO graphics card require an additional power connection and why?
A2: Yes. RADEON™ 9700 PRO has so many advanced features that it requires an additional power connection to attain maximum performance from the graphics card. In addition to installing a RADEON™ 9700 PRO graphics card you are also required to plug a power cable into the graphics card and to the power supply. Connect the 4-pin cable of the Power Extension to the connector provided at the corner of the RADEON™ 9700 PRO graphics card.
It doesn't necessarily say that it requires more power but that's what it sounds like.
