I buy two old style AT SMPS to powering my 3A DC Motors.
Shorted the four power pins - Live to live, neutral to neutral.
But when I turn mains power to AT SMPS, fans turning for 1 sec and shuttuing down.
I know in ATX SMPS you short two pins but something similar too you do in AT style?
Thought that in AT SMPS it turn always on as long as you shorted the four power pins - Live to live, neutral to neutral?
