I hooked up the MPJA supply to a 13.8 V 10A supply in my house, and it worked great with the computer. I then took it out to the car and hooked it up to the lighter socket. I tested the outputs and they were OK. I then connected the computer, and it destroyed the supply. Anybody have a clue as to what I did?
how do we hook it up to the motherboard? is there a pinout diagram i can look at?
To hook it up just follow the previous post on this message, you've the schema for power outppput and just have to make it fit with your mobo.
follow what posts? i have tried hooking this thing up and am having no luck. when i stick a volt meter to the differant wires. they are all reading +12v.. even though as pin 10 states that it should be 5 volts. any ideas?
Where can I get ny hands on one Dowunder?
I'll try that again, this time in english.
Where can I get my hands on one of these PSU's downunder here in Australia?
Sure you can split one of the +5V leads into two to give all your MB's +5V inputs power. Many motherboards merge them all when they enter the board anyway, so it's no big deal... I've powered a motherboard using just 4 wires (+5V, +12V, -12V, GND) and it worked fine...
The main reason they use so many leads with the same voltage is for current carrying capacity. If you were a PSU manufacturer, would you rather run a fat, single 8 ga. wire or several 16 ga. wires? It's easier and more cost effective to use several smaller diameter leads to pass the current. Plus the connectors don't have to be massive, etc.
Just some info you might find useful...

Ok.. i'm one of the unfortunate that blew his power supply up too.. i'm thinking of either buying another or just going with invertor..
Am i wrong when i connect all the +5v pins together and wire it off to the motherboard like that? is that why it blew up?
I was acutally trying to run the dc-dc convertor off of a PC power suppy... is that another reason?
Hi Guys well could u pls tell me as to what power supply are u looking at.. i mean the link pls
i think this post is over 4 yrs old, don't think those guys are going to answer, maybe...
