Well Purifi looked at the Eval1 and Kim said it was in perfect working order. Also liked Ghent's wiring harnesses, so I guess I'll be using them. The repaired SMPS arrives at my door tomorrow. Still no idea why the aux section blew out twice. Hypex said my six pole harness was perfect, and they didn't check the five connection b/c it wasn't crimped (It wouln't have been given I was using the 3M IDC connector) but said it appeared to be wired correctly, so I have no idea what the root cause for these failures.
I will check out the SMPS by trying Ghent's LED first, then when the Purifi arrives I'll connect it with Ghent's harneses. If all the Leds light up, only then will I reinstall it in the case, first with the back off. If it works that way, I'll reistall the back and cross my fingers.
I put thermal paste under the base of the SMPS, could that possibly have caused any issues? Anyone know?
