I have a 733 G4 Graphite with PSU problem, power button lights up for a second and it would turn off again ...
After measuring the PSU's output, I found out that the 28V was only live output (everything else was complete dead). I rewired an ATX PSU and relocated the original PSU to the area under the CDROM/Zip drive. Now my system has two power supplies, one for 12, 5 ,3.3 volts (ATX) and the original PSU that provides only 28V to the logic board. And everything works perfectly. My 17" LCD studio Display ADC works very well too.
