my rig using cooler master 750w (rs750 acaa-a1 with actice PFC)
last night a loud 'pop' sound came out and my rig suddenly goes off...
i notice motherboard's LED is not lite up anymore(normally LED is lite on even not in powered ON state)
i try to powered my rig but nothing happen. from visual check, no sign
of burning IC's or blown caps on my motherboard..so i guess it would be my PSU die ady...because i check the 24pin connector with multimeter, no sign of power from PSU at any pin.
just wanna ask, what is the item damage usually when 'pop' sound happen on PSU? is it power IC's? or Caps? and it will cost how much to repair? my PSU dont have warranty anymore...TQ in advance
Have you tried jump starting the power supply?
You can test the power supply by taking it out from your system, plugging some fans to it via the molex connector, and then jump-start it by connecting a piece of metal wire from a green wire to a black on the 24 Pin. If it's unable to start, its LED light beside the power switch should light up, indicating that there's something wrong with the power supply. But if the LED doesn't light up and the fans do not run when you try jump starting the power supply, then it looks like your power supply is indeed dead.
