I have an old PSU, model LPK9-4P. I'm trying to power an Arduino project with it, but it doesn't work as expected.
PSU is wired with a switch between signal and ground, and powers on well. Measures shows voltage in every line. But 12V line, with just 2 fans on it, just works few seconds before falling down.
5V line is stable and working, powering arduino and a bunch of sensors.
Is this about load requirements? A malfunctioning PSU? I'm kind of stuck with it, and it's just a testing power source!
