Gigabyte 512 mb 8800GT - Not enough Power ?

[ademcg]

I have had a bit of a mare recently with this now mobo and Vista 64, relating to graphics from the 8800GT card I have.

Since I binned off Vista and installed good old XP Pro, and following the installation of the latest nvidia drivers, a pop up box appears on logon stating the card is not getting enough power and needs suplimentary power/ ?? and has throttled back for safety

I guess this explains my crappy 3d06 mark

I have the Enermax Galaxy GPU six pin power connector hooked up and its in my PCI-Express slot 1...activated in bios...what gives ???

Anyone else had this ???
