I've got a NVIDIA GeForce 7300 out of a Mac Pro 1.1. The caps have the following markings; C67A 330 16v. Is this 300uf cap? Can it be replaced by a
300uf 16v electrolytic?
300uf 16v electrolytic?

Can't know that unless you know the ESR and Ripple for the old cap.
Can't know the ESR and Ripple for it until it's brand and series are identified.
Don't really even know if it's a poly or a lytic until you ID it because both kinds come in both style cans.

Re: Identify Caps On A NVIDIA 7300
My guess is it's a 330uF 16V poly, in which case, https://www.badcaps.net/store/produc...products_id=78 would probably workI love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Just archiving everything related to bumpgate since most stuff has disappeared from Google. Maybe people will finally take the time to read some of it and stop shouting "reflow gpu" at every occasion but rather try to understand what the real issue is…
Interesting parts about the failure analysis are "Why Nvidia's chips are defective" and "Why Nvidia's duff chips are due to shoddy engineering"
May complete this post at a later date with more details.
Basically issue is a combination of thermal dissipation of the chip with hotspot,... -
I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).
