When I install my HIS ATI Radeon 9200 video card in the AGP slot, the EFIKA will not power on. I have also tried my Radeon 7000 that I know used to work with my Pegasos II, same results.
The unit will power on fine with a PCI Voodoo 5 and will also power on with out video and just the AGP riser installed.
Nothing wrong with it at all, just not compatible I guess. 460 Watt that I pulled from my overclocked Q6600 - worked fine. The only reason I replaced it was to get power supply with a 120 MM fan.
I pulled out an old no-name brand and it worked fine.
The power supply that didn't work was a Cooler Master
