Looks like I fried my Apollo, I'm after advice on how to diagnose if it's worth trying to repair it.

This is what happened before I let the magic smoke out:

I dug out the unused Apollo to use it for a bit of heating. Powered it up with a monitor, running Armbian on the OrangePi and starting the miner via the sudo ./start etc etc command prompt in a terminal, all worked well.

Then I plugged it into a 2kW PSU but I used cables that came from a different (650W) PSU. Nothing seemed to happen except it smelled a bit funny....

The I used the cables that are the correct ones for the 2kW PSU, and now the Apollos fan turns on, the all lights are out and it's dead as a door-nail.

I already disconnected the OrangePi and tried to power the miner via laptop and USB, but same result, fan spins, nothing else happens.

I find it hard to believe that they make cables labelled PCIe on one end, with an 8 pin connector at the other end that will it into different PSUs that use different pin layouts at the PSU end, but that seems to be what happened. Bastards!

Any idea what part of the Apollo would have fried due to this and if it can be repaired?

And is it possible that the OrangePi may have survived the 12V getting connected to the wrong pins?

Not all PSU's are pinned out the same (stupid I know) Sounds like you've shoved 12v into somewhere you shouldn't have
