I am looking at buying a Kinter 12v 2a 2ch mini amplifier that does not include a power supply. The power connection for it is a 2.5/5.5mm barrel type. I actually want 4 of them and was wondering if its possible to power them all from my PC's PSU? I have looked around for molex > barrel cables of the size I need and seems that there are none (except for custom made). If its not possible to power them from my PC's PSU then im looking at using my A/V receivers 12v triggers(x2). The triggers are 5a output each, so could I split each one to trigger 2 of the mini amps from one trigger and the other 2 from the other split trigger?

You can do this. The +12v cable is yellow one, and the ground is the black one. I am running my RGB LED kit from a very old computer power supply, just did some soldering on the power supply and i was ok.

Edit: You can buy a very cheap psu just for this purpose. Computer power supply can do 3.3v, 5v and 12v.
