Can anyone help with this? I've recapped the board as it was having trouble.. but it's still having trouble. Used two different new ATX PSUs via an AmigaKit adaptor.. but it's only 4.7V on the +5V line, which means it most of the time doesn't boot up.
This is with any hardware on board, by the way (not even a CPU card sometimes!).
Does anyone have any suggestions? I'm just recapping the board... again....
Where are you checking for voltage?
Did you check the motherboard plug and socket? these are notorious for corroding on the 5v pins and or the pins spreading apart and making bad contact( i stock these connectors if you need them). Assuming thats not it, i have found a trend in atx psu's that seem the 5v line is set low from the factory,since they concentrate on 3.3v these days i dont know if this is sloppy adjustment of the 5v side or they just dont care or?. I have had several new ones out of the box that barely make 4.8v on the 5v rail when checked loaded. Some older 200-300w psu's i find regulate the 5v rail better imho. the 4000 will happily run on a 200W psu in most cases.
