What specs is the BPPC??
I'm running a 040/160/SCSI with BVision with the normal 5 pin power connector connected to a ATX PSU. I have power to the floppy power port as well as power directly to the BPPC card through it's fan connector. The three feeds will give you a stable computer, without the need to soft reset on power up, to get the machine going. At least it did with my setup.
