Hi
And greetings from Norway. This will be my first post here. Apoligies in advance if my english is not up to scratch
I've recently attempted to convert an ATX PC power supply in order to power a high power lipo battery charger. However i'm having little luck. I have earlier done this with success using an older 200w supply, but needed more power and bought a new 950W one. On paper it should be capable of 64A on 12V which suits my needs just about right.
But this is what happens:
Firstly, when i plug it in, ( or flick the mains switch, whichever results in powering it, but not starting it) most of the time, it will overload the fuse and im left fumbling around in darkness
Got 220-230V in my outlets and have tried powering it through an otherwise unused 10A fuse ( or mains circuit? whats the word?
). Infact i tried all my outlets and blew all the fuses just to make sure
resetable fuses
However, on accation the fuse will hold, and i can get on with testing. I then connect green wire to ground in order to start the supply but all i get is a short flash of power ( fuse holds ) before it shuts down again. The cooling fan will spin one revolution at the most. I can do this as many times as i like but the same things happens.
I have tried adding various loads to all the outputs, ranging from about 4-100w (but never above specs), but makes little to no difference. In one case the psu would keep flashing as if i were playing with the switch. Otherwise, nothing
Am I missing something, or is the supply faulty, perhaps?
