Rememer the days when your computer couldn't shut itself off and had a big, heavy manual switch on the front? I am building an external radiator / pump / chiller box for my watercooling setup, and I was considering using the old AT power supply from my ancient P166 to power all the fans and TEC's inside the unit.
So, I took the power supply out, plugged it in, pressed the on switch (if you remember, they are connected with a big long cable that spans through the PC case)... the fan on the supply spun up for a second along with all the fans I had connected to it. Then, it went dead. I repeated and got the same result.
The power supply is far from being overloaded, so this is not why it keeps on shutting off.
One thing that comes to mind is the "Power Good" signal that a power supply sends to the motherboard. Even the old AT supplies have this feature, consisting of an orange wire that sends a +5V DC signal to the motherboard in order to start up the system once the power is smooth and stable. Perhaps I have to connect this power good singal to a ground wire in order to keep the power supply running?
If you have any other ideas, I would greatly appreciate them... Thankx, Felix
