m4 ATX power supply question
Just got my brand new M4 ATX Power supply and i hooked up wires according to directions. As alwayz i want to test it, therefore i let the dip switch to just power supply mode with an external on/off switch from the board.
Unfortunately, nothing turn on, but there is a LED light power on from the M4 ATX but not from the motherboard. Then i do some Volt check, notice all the wires are all 12V positive (the - wire, the acc wire, yellow black, red ....)
How come? anybody has the same problem....hate to go back to my inverter
thanks in advance....:nw:
