I had an antec sp500 blow up recently. I had to discard it for similar reasons but now wish I had just torn into it and got it done. It was a nice psu with 35A on the 5v, and it was an early modular design. RIP your ocz and my antec.
Would have thought the input side would be the first thing to check, shorted MOV or input bridge rectifier, not sure a secondary side side component would be a hard enough short to trip the breaker
Like I said in the video, I'm not well versed in electronics repair. If something is visibly blown or easily tested I can usually do it but the theory of how it works or should work is beyond me. If you have any ideas of what I should check next I'm all ears.
I buzzed your elbow about 20 times, long distance of course. 😂 On the plus side, you got the pigtails, and you can blow a fuse every month and have a replacement close at hand! You win some and ya lose some, but you got some more experience fiddling with it, so it was probably worth the $5! Keep it up guy, love your channel.
@@idoesstuff1 11:33 That blue component to the right of the yellow capacitor might be the MOV (surge suppressor), not sure if the pair of parts below your left thumb are the input bridge rectifier - it can be anything from 4 individual diodes, through 2 pair packages, to a single FULL BRIDGE RECTIFIER package. The input rectifier often doesn't need a heatsink, or only a small one, as its mains voltage at not many amps. Also, the input rectifier will be between the mains input wires and the main capacitors
So let me get that straight - you FIRST tested the mains fuse, found it was bad, and THEN tested for a short between mains live and neutral only to find none? Well, _duh._ At this point, testing should have continued *after* the fuse, not before it. As previously suggested, the fault is likely to be somewhere more towards the input side - it could just be an X capacitor or MOV, but I would look for a shorted bridge rectifier diode or a shorted MOSFET in the APFC circuit or in the main switcher in particular. As old as it is, the big filter capacitor may not withstand a high enough voltage any more either, which is a much harder thing to test for. This power supply is a bit past its useful life anyway, but it could still be a decent learning opportunity. BTW, dead SMPS can "bite" quite badly if they are still alive enough to be charging the main filter cap. So always check that guy for remaining voltage.
I cannot stress this enough. I can read a multimeter and I know just enough to test simple things. The theory of how it all works isn't something I'm well versed in. I'm trying to learn more though.
Careful with those modular cables. Those types of cables aren't standardized, so they're not necessarily compatible across manufacturers.

@@idoesstuff1 Haha, fair enough!
