Just yesterday my Silverstone SST-ST1000 PSU stopped working. Everything was fine until my home experienced 3 sudden power outages (On-Off // On-Off // On-Off) within 20 secs. When the power came back on and remained on the PSU did not come on.
I am not an electronics expert whatsoever but still want to be sure the PSU is dead for good. I figured the internal fuse was to blame so i opened it up and finally located the fuse. 15a/250v it claims. (see photo below). I performed a continuity test = failed AND a resistance reading = 0L. Great it seems the fuse is to blame but i have no replacement. And im still wondering if the rest of the PSU is ok.
I decided to strip off some 12/2 wire (rated for 20a) and stick it where the fuse used to be. The logic being this should be fine since im sure there wont be some surge coursing thru my house at the moment of turning it on. I also jumpered ATX / MB pins 16/17 (the green and black) and added the PSU power cord. At this moment the PSU is still switched to OFF. No load attached.
With the above all connected the plan was to turn the PSU to the ON position to at least see a green led light (the LED is right next to the PSU power switch) indicating power is there but i didnt expect the PSU to kick in and turn on its fan since there is no load attached yet. I went to turn ON the PSU and i got a SPARK and POP. I quickly switched it OFF.
What did i do wrong? Was the temporary jumper wire a bad idea? Does this test prove there was something further down the line that was damaged during the original power outage OR did i unwittingly damage a likely working PSU since i didnt replace the dead fuse?
Thanks for explaining.
