This cap needs to be replaced on this 290x BF Ed. GPU. Unfortunately I broke the leads on my first repair attempt and I'm looking for a replacement part. Does anyone know what is the capacitance? The schematic name is C617. Can you order a part with a similar form and capacitance at say digikey or mouser?

PC
330

225 = 22 x 10 ^ 5 pF = 2.2uF (2.2 microFarad)

PC should stand for [strike]Polycarbonate[/strike] Polymer Capacitor, but that one looks like its an Aluminum Electrolytic Capacitor.

That 330 is what's bothering me, it should mean 330VDC, but that seems a bit extreme. Or maybe it's the other way around (250V 33nF), but I don't think so as the capacitor looks too large for 33nF. Is there anything noting which is the capacitance and which is the voltage? This can change from one capacitor to another.

Some choices of 2.2uF 330V+:
