Looks like some kind of input filtering,? (On the flip side of molex power connector.) Size is 1210.
Any idea on required values? BTW, card works.

The Ati R480 application notes are here -- https://www.scribd.com/document/504034393/AMD-RADEON-R480
You should be able to isolate component/value from that =)
Thanks. Schematics are for PCIe variant, but still hold C1165 and C1166 on external power input (12V). They are specified at 10uF 25V.
Assuming that the capacitor next to it is identical, you could desolder that one and measure its capacitance and voltage.

That'd be right ~ we're only concerned with the 12vdc power to the R480, not the bus type.

I know. But I don't have hot air station and I don't want to crack the other one.
