That is a great idea about the 5 volt output. I'm gonna do that this weekend to my power supply. Would work great for setting up an airplane. Some Ernst charge jacks and a long extension would be the ticket.

I use a FMA Direct Supernova to charge my hobby batteries...works great. That runs right off 12VDC.

You're right, it would have to have a peak detect or a similar shut-off device. I'll get a charger made for the task, thanks bro.

NICE THREAD dude.

MAN, very informative.
Max we need to sticky this somewhere.

Yeah, just use the PS to power the charger, that's all.

Mike,

I've pulled my old power supply apart and found that I do not have a green wire, but I do have a single blue wire that goes into a part of the board that has -12V next to where its soldered into. Is this the same thing?

Regards,

Dean

Dean do you know if it is a ATX or AT power supply? is the motherboard plug in 2 pieces and flat with all the pins in 1 line

DesertHucker · 02-01-2007, 11:35 PM

Just finished making mine had a 430w thermaltake PSU that would not turn off, therefor did not need the resistor.

Mike if the PSU needs load across the 5v rail to keep it alive, would a load across the 12v rail do the same thing?

Was thinking if it did then a charger on the 12v rail would give enough load to keep it alive?

Lawrie, I would not have a clue mate. It's out of an old PC that is about 9 years old. Does this give you any clues. It's also only a 200W. I'm probably better off trying to get hold of another one. What do you think.

Cheers,

Dean

If it is 9 years old most likely be AT it would have a long lead with a switch on the end.

Dean i got a couple of 300w ATX PSU's here if you whant to drop by

The load has to come from the 5V rail as far as I know. I've tried using a load on the 12V side and got nothing.

If it's that old, it's probably an AT and 200W most likely wouldn't be enough. Can you post a pic of the supply and connectors on it?
