Hey,
I have a Gigabyte 980TI Windforce. No shorts on the main 8 pin PCIE power connectors. The 8 phase buck converter inductors are showing 2.5ohms.
The card doesn't power up at all - no lights, no fans, nothing. I noticed that all of the 8 phase inductors are showing 0V. I couldn't find a fuse for the 8pin power connectors.
I did notice that the PCIE x16 connector 12V line has a fuse F3 (10A marked on it) which is blown. It is reading 16ohms on one end.
1st Question: Is there some logic on the board that checks the 12V on the PCIE x16 bus connector before starting up the 8 phase buck?
2nd Question: Where does this 12V from the PCIE x16 connector usually go to? Which rail does it power? I couldn't see any inductors close to it. Obviously, I don't want to just bridge this fuse knowing there is a 16ohm short somewhere.
3rd Question: Is there really no fuse for the two 8 pin PCIE power connectors? I couldn't see one anywhere! I find it hard to believe.
