Hi,
I have an ATX power supply 400w that I've broken out to use as a bench power supply (-12v, +12v, +5v, +3v).
I'm going to wire it up with an LM317 for variable voltage output.
I understand that the current rating for the +12v is quite high (~8A), but I've heard that the -12v rating is much lower (~.8A) ... I would likely by using -12v to +12v to get 24v output, and I want to know the current rating of that voltage supply.
1)Does anyone know how to determine the current rating of the 24v output, and if
2)Using a voltage regulator + linear stepdown converter would help mitigate any current issues over 1A
thanks!
