I'll have to put the meter back on one to be sure, perhaps it was 18v, it runs out through a two pin jumper back to the MB, and the over to the firewire adapter it looks like.

The P4 is a 4 pin connector from the Quicksilver PS to the MB, looks like it suppies 12v (x2) and at least one set provides extra power to the cpu board.

Anyone know which of the 3.3v lines services the AGP bus? smile
