G-Rex Trouble

[harryjon35]

Hi there !
I have the following problem with my new G-Rex 1200 and
I wonder if anyone of you can point me in the right direction...
I installed the G-Rex correctly onto my BlizzardPPC, but when I try to start the Amiga it won't power up. Strangely this only happens when I connect the P8/P9 power connectors to the PCI board. If I unplug them, the Amiga starts up. It is even stranger that the G-Rex accepts the PCI cards plugged into it even with no power connected. Currently I use a nic and a Virge GFX-card that way. But as I plan to use a Voodoo in the future I'd really like the PCI-bus powered...

I'm completely puzzled.  :-?
Any ideas ?

Bye,
 Harry

If the G-Rex doesn't work with the AT supply there probably is something wrong with the PSU. Try using an ATX one.

It IS a ATX PSU. However it has an adaptor from ATX to AT.
I thought that I need some sort of PIC to connect an ATX PSU to the G-Rex (?)
I don't think that there's anything wrong with the PSU as I've
already tried another ATX PSU...
