again I see the psu is the problem! I cannot believe it! 3 different ATX psu's and NONE works fine! what the hell can be wrong? Using both elbox and amigakit.com psu adaptors! only the original 4000 PSU can really drive the 4000+ppc+grex , no matter if the atx ones have 2x watts!
Hi Keropi,
I also have trouble with CSPPC + GREX + ATX PSU + adapter from Amigakit. The Amiga boots only from time to time. I tried a microATX with 200W and a standard ATX with 300W. Same symptoms. So I replaced the GREX + Voodoo + PCI NIC + PCI Soundcard with a CVPPC + Zorro cards and now it works.
With the standard PSU it worked with GREX.
I wanted to replace the standard PSU with a smaller one with silent fan.
So what is missing when using another PSU ?
