Switch Mode Power Supply Not Starting. In this case, i start by. if switching power supply fails to oscillate or presents malfunctions caused by switch tube, in most cases the voltage at both. Smps can fail in many different ways, the most common being no output power at all. This isn’t shown in the example given above, but it is a fairly. The problem can be described as following:. 1) remove the mosfet from the pcb and check it with a multimeter. no output, good fuse. before blaming the power supply, make sure the outlet is live, the main power switch (if any) is on, and that any line voltage select switch hasn't changed. a fast reset of the psu might avoid that long enough to apply a load, but a long reset will engage the 5v rail to power. many power supplies use a “kickstart capacitor” to supply current to start them up. most atx psu just won't power up without a load and start making a clicking sound, caused by an internal. 2) without any doubt you will find the mosfet being the faulty component, so you can quickly go for a replacement of the same using a correctly matched mosfet.
