Why Are My Gridseed Blades Exploding? What Components Are Exploding?

I'm wanting to get into mining not so much for the mining reward but because I support the idea of decentralised currency and the power of peer to peer transactions.

However I have a problem with getting some Gridseed Blades up and running. Something on them is exploding. Please see the below photos.


This is my power supply unit.

I live in the UK so the voltage is set to 220V mode.

This is the front of the PSU wired up. My multimeter reads 12v coming from the output.

I'm in the middle of building a stack of blades but I need to overcome the problem of something in them exploding.

In this photo you can see there are three components that have exploded. What are these components? What would cause them to explode?

This photo is for comparison, this is a good blade where the components haven't exploded.

I've tried to look for a datasheet or a gridseed blade board schematic but I can't find one.

Every time I connect a blade to my power supply these same components explode. What could be causing this to happen and what could I do to stop this from happening?

Also I would like to repair the Gridseed Blades that have already exploded, is there a schematic for this board, or at least what are the components that have been damaged?
