refurbished.When you think of Hackintosh build, you may generally think of an Intel-powered rig in a big and bulky PC enclosure. I'd be willing to pay upwards of $150, since my dual g5 supply costs $290. Better yet, market an adapter harness and sell it. If you manage to figure out something that works, let us know. If you don't have that socket, you probably don't need to worry about the 25v lead.
Actually, it's a 6-pin socket between the AGP and the case (it looks like an extension of the AGP). Your 25v lead is supplying the power for that ADC connector through the motherboard's AGP. The ADC is a single connector that provides DVI video, USB, and up to 25V to power the monitor (it doesn't have its own power plug). Depending on your g5 configuration, you may or may not have an apple display with the proprietary ADC plug (looks like a large DVI). The only insight I can give you for certain is on the 25v lead. So, although you don't want to go over on voltage, more amps is not going to hurt anything. Most rooms carry 15-40 amps to their circuits, and a 120 watt bulb pulls 1 amp (1 amp x 120 volts = 120 watts). Amperage is "drawn" by a device, so high amperage is not bad. The good news is that if you find some ATX power supply of the Gods that can supply an enormous amount of amperage, that's fine. I've "reworked" power connectors in x86 servers, but usually the power requirements match up fine. If voltage drops too much, hardware crashes or refuses to start.įrom my best "guesstimate", I would venture to say that the p1, p2, and p3 connectors are for motherboard, drive cages, and CPU (respectively). If you draw too much amperage from a power supply (provided it doesn't shut down), voltage drops. The voltages are a good place to start, but you are probably going to need to know what the amperage requirements are for the voltages. Hey juragan - I'm afraid I won't be too much help on this, as the differences between x86 and g5 processors will undoubtedly carry over into their power requirements. I know some of you in here have much more experience and knowledge in the G5 hardware that can share with us.
The rest is mostly there in the ATX 2.0 PSU. Another thing is the pin# 3 is i believe for fan tachometer (sensor). What we have missing so far from G5 PSU is the +25V (i mark with red box at P2 pinout) which i dont know for sure what kind of device or component is required that kind of voltage. Here's what i got so far from the ATX 2.0 pinout
