Good day all
Trying to use PC power supply, which says it is rated to 500W to power my general house video cameras, 4 of them, each rated to 1amp max. I connected green wire to black, and it is working.
however...
The supply is (at least written on label) rated to give 20A @12V (yellow cables),but it shuts down at 4amp.
The protection circuit works for sure. Another thing is, I connected 12V 5A dc motor to it shortly, and I think it did cause the problem, damaging something.
Anyways, is there any particular reason what causes the supply to shut down not reaching even the 1/5th of its rating and solution ahead, that I can do to make the power supply to put out even not its full rating, but at least 6-8 amps?
thanks ahead
