I bought a 50W Touch micro ATX (SP9627) PSU. I cannot seem to figure out the wiring arrangement. I looked at the formfactor spec. It would seem to indicate that there should at least be standby power even when "off", but I cannot seem to find it. The connector is a 24 pin (2x12) connector, slightly different shape than the standard calls up (no locating "rib"). There is a 3 position connector for the power switch... I jumpered a pair of the terminals and that started the PSU. Can someone tell me how to wake this thing up? Thanks!  |

| Make sure you have sufficient load on this supply - on the +5v and I forget maybe the 12v as well. I usually connect an old hard disk and a load resistor on the +5v - It's a switcher and running without a load will damage the supply. |

Might be too late for this one? I already started (maybe... the fan was running) the PSU without load... It does not have a HD connector. Just a 4 pinconnector for a MB? The other connector is a 12 pin... not 24 pin as I had thought first. No green wire.. On the 12 pi, I have a bunch of black wires; one yellow; one orange; one white and three red. Further comments? |

| Typically there are a couple four-pin connectors for the disks (floppy, hard disk etc) and a larger connector for the motherboard, which varies. I'm not up on all the different configurations, but there are several sights out there with info. Here are a few I have used in the past: Be careful, this is not simple linear stuff; it's serious and dangerous!!
