I just purchased a used S9 14T antminer and upon inspection found the aftmost of three 1000uF capacitors under the pci-e sockets broken off with a screw hole in it. The hole lines up with the fan screw, so it appears a too long screw was installed.

I've order a capacitor matching the labelling (Aluminum polymer 1000U 16V) and will attempt to replace.

I was reading of others with capacitor issues and still run the miner. Given proximity of the cap to the power inputs, I'm guessing these smooth the input voltage..

Any thoughts? Do I risk further damage to the board if I try running it? Should I start my testing with just the other 2 blades connected?

Thx.
