Re: Troubleshooting Question

Look at my PS2 power supply repair. Fluke 289 didn’t see the bad cap. Neither did my Fluke 179 and the Agilent DMM. My Agilent ESR meter found it right away.:o:

Re: Why does my Seasonic SSR-500GB3 whine??

I’d agree with red wire, but since the psu is doing this day one, it would be stupid from Seasonic to sell something like that doesn’t have enough capacity on a certain rail.
