The PCIe 1.0 specification can feed your card with 75W of power while PCIe 2.0 can serve up to 150W per PCIe connector but for the safety and compatibility reasons Radeon HD 2950GT will come with a single 3x2 power plug.
This card should do fine even without the connector on a high end PCIe 2.0 board, but then again we believe that ATI will ask you to plug it anyway even on PCIe 2.0 boards.
The Geforce 8800 GT also needs a power plug and so will Radeon HD 2950PRO and XT.
Radeon HD 2950 GT has 80W TDP
