Hi  I've just purchased an ATI Radeon 3870 graphics card for my G5 but when I went to install it, it says it needs to be plugged into the power supply on the board.  I have tried looking everywhere online but have not been able to find a board diagram showing where the power is?  I found this: http://lh5.ggpht.com/_NydkaYpC…..G_0168.JPG

but looked by the 1234 rack bit at the front of the machine and it looks different and there is no 4 or 6 pin connection coming out of the board in that place?  Can anyone help on this for me?

Many thanks

Antony
