|thanks for the post jam|
what i did is check the green and a black (ground) wires
my cooler master silent pro 600w was DEATH. it has no power from the green wire.
instead, one of my old psu was still alive, it read 9.73V of the 10V on the green wire.
later, i bought a generic 650w psu. i checked it and read 5.00V on the green wire.
when i plug it on the mobo, the standby LED turned on! and i turned on the whole mobo and beeped because it hasn't ram.
but i'm happy i found that the problem was the psu!!!
WHY COOLER MASTER??? WHY??!?!?! WHY IT DOA?!?!?!?
