Hey. I've got a pair of 980ti graphics cards that I'm trying to get working. I bought the pair of them 'broken,' but one of them was working great. Then one day I noticed it wasn't working as well, but still working ok. Due to unbalanced power draw on the 2 pcie power connectors as well as early power throttling, I figured it was a VRM issue. Took it out to fix it up.
These cards have an 8 phase VRM. On the output there is a pair of components is parallel that look like diodes. On the non functional card, 2 of these components appeared burnt. On the functional card, 1 appeared burnt. I went on Mouser and ordered the only diodes that had "330" in the part number (3A 30V shockey).
Anyways, diodes came today. It was immediately apparent that they were the wrong package, and shortly after I was brilliant enough to realize that I was looking at capacitors. The reference designator wasn't a big enough giveaway the first time I suppose. Ugh.
Anways, 330, are we really looking at 33pF caps? That seems really small for... a 250W VRM. And can anyone point me in the correct direction of replacements? Or maybe I'm still missing something?
