I have a Batch 2 (3 module) that has just had the PSU fail on it.

The dead PSU is the 850w Enermax that came with it.

I grabbed a 1000W Cooler Master that i had sitting around from old GPU rig, and i have tried to switch it out.

The 4+4 cables from PSU are plugged into the White sockets.
The 6+2 cables from PSU are plugged into the Black Sockets.

I have the 20+4 cable plugged into the 24 pin socket.

The avalon will now power up to the degree that i can reach the router inside it, the router connects to the Wifi and has blue light. One of the boards inside has 2 green lights and they both go on.

When i power it up the fans spin for a moment and then stop. Same with the PSU fan, it spins for a second and then stops. The two external lights show me 1 green for a moment, but it then turns to a constant Red.. the orange light is also constantly on.

When i removed the cables from the original 850w PSU i only removed 2 x 6+2 cables from black sockets, but have since found there is a 3rd black socket, so in an effort to get it running i ran another 6+2 to that black socket.... still no love from this machine.

Anyone out there able to tell me what is wrong or what i can try?

I have plugged and unplugged and replugged every cable and several decades ago i used to build PC's for a living, so we can cross that off the list, it's certainly not a poorly seated or lose cable issue. My fingers are nearly bleeding from all this plugging and replugging.

As the PSU is powering the router and lights and fans for a moment, i am working on the assumption that the PSU functions fine, it surely did last time it was powering GPU's

The red led indicates a +12v supply failure.
The 6+2 connectors on some psus have the +2 section wired with +12v and gnd instead of 2 gnds as the sockets on the avalon are using.
Plugging in the pcie connectors with this type of +2 section shorts the +12v bus on the psu causing it to go into an over-current shutdown.
Just leave the +2 section of the pcie connectors unplugged, plug in the 6 pin sections and you should be good to go.
