Question about Bestec ATX-1956F (ATX1956F) 200-Watt Power Supply
There are no Leds or Post when connected to Power. The PSU Led starts as a a steady green but witha second goes to a reduced steady green. The fan is not rotating. When the Desktop On button is pushed, the PSU reduced steady green goes out.
Have disconnected all components attached to the PSU and the PSU Led remains a steady green which should indicate that the PSU is working but the fan is still not rotating.
Because the Fan is not working is the PSU faulty?
Sounds like your power supplie has not been switched on by *********** board.the fan will not turn on until power supplie is turned on by mb.as far as what is wrong there are several things i can think of.i would try resetting bios. It sounds like your power supplie is working and your motherboard could have a short.but i have no way to be sure without testing. I can however tell you how to perform a test on your power supplie.unplug the 20 or 24 pin connector from your mb. look for a green wire,and then locate the grey one.short these two together(you can use a paper clip or something).if it dosnt power up. your power supplie is bad.also do not short any other wires,and only touch the grey and green for a few seconds as this is not how it was intended to be powered on.
