Re: SST-ST45SF-G failure 3.3/5/12 lines but not ps_on or 5vsb

Disregard the images. What I suspected as a discolored component was actually just a drop of factory flux that cleaned off.

Re: SST-ST45SF-G failure 3.3/5/12 lines but not ps_on or 5vsb

It's apparent to me that anything beyond the obvious (physically damaged components) are out of my scope since I only have a basic electronics understanding (my professional field is clinical laboratory science.) If it's not an leaky cap or a failed diode then it's beyond me and i'll just junk it. Sorry to have wasted your time....

I have a SST-ST45SF-G that has failed on all of the 3.3/5/12 lines, but the ps_on (green wire) is reading 3.7v and the 5vsb (violet wire) is reading 5v. I disassembled it and checked for any swollen or shoddy looking caps but found nothing. No components are discolored, nor do I see any scorching. It all looks perfect. It's a SFX so it's possible i missed something but i looked very closely. No sounds or fan movement either, even when the paper-clip test is done. I tested everything strait from the PSU with no cable attached to make sure that wasn't the cause. The fuse checks out as well. I checked...
