Where is 5V,12V rail generated - PALIT 980Ti

[whc14765]

I have a PALIT 980Ti 6GB givng me a black screen.

3.3V is present, 5V is not. Does anyone know where 5V is created?

What is 12V_PEX8_F?

I have PALIT Jetstream 980Ti 6GB missing a 5V rail, it seems that the 12V_PEX8_F (probe point) near the 5V buck converter is missing.

I have never heard of a 12V PEX rail, what is it??
Also, I thought that 5V is turned on first, then PEX??
