Good day all.
I've been using PC power supply to power up my electronics, and when today I added battery back up to the system, it failed.
Want to mention one stange fact: as we now, there are about 10 of +12V wires (yellow usually) coming out of the supply, and I used 3-4 of them to power up several parts of circuit. Today, I've connected one more yellow wire to Lead Acid Battery through the relay, so when mains supply fail, the circuit would've been connected to battery. The battery voltage was ~ 12.6V at the time of connection....
after 3-4 mins working, the one single yellow wire which I connected from power supply to battery FRIED, like fuse...the rest of yellow wires were ok...
so question is, can 12.6V cause failure? the supply now works about 50%, i.e. when I connect a load to it, 1st time it fails, 2nd time powers the load, 3rd time fails etc....looks like some protection circuit is functioning..
it is 11pm already, and I'm to tired to think deep....appreciate your feed back.
