Hello All,

I'm finally back with some news.
I received the chips and some others components.

This week, i replaced the G7G5 DS1780 chip which is in charge for measuring the PCI 5V.
And i have the regret to inform you that the issue remained.

So after an extensive reading of the LTC1629 datasheet and measuring some key tensions ( RUN/SS, EAIN, Ith, etc).
I decided to exchange this chip with the one in charge of the 3.3V.
And to my surprise the PCI 5V is now operational and so does the 3.3V next door.

Well at least the 3.3V was operational for a few minutes, and is now faulty with 0.98V.
So i guess that the LTC1629 is faulty and i'm gonna need to bite another bullet (16€/piece).

Thank you for reading me and I will keep you informed ASAP.
