XT60 Power Connectors

Modified one S7 to try out the XT60 power connectors on the DC side.
So far so good.

Look nice and beefy. Power delivery ok to the boards?

Nearly.
Some voltage drop I'm going to run this on the bench tomorrow and tweak the PSU's to 12.5v at the Miners.
I've dropped about 0.12 th/s on this miner.

Luckily the DPS-1300's have a potentiometer under an easily removed cover, rather than taking the whole power supply apart.

I've nearly made a small PCB with three soldered PCI-e receptacles and an XT60 on it.
The idea is for the PCB to push straight onto the miner then plug into the power supply.

The PCB is a paxoline sheet with two 1.5mm thick copper bus bars glued on it then drilled.
I'm using a 100 watt iron and an SMD rework station to get the heat up on the copper to solder, whilst resting them on a sandwich toaster hot plate I made a couple of years back.

It's not a PCB as PCB's go, but I've got a much larger chunk of copper to handle the power.

Not sure if the wire you are putting it too is high enough gauge for a single strand..

Beyond that: When using a DC bus system that can easily supply current far in excess of what a miner/hashboard needs, ALWAYS fuse EACH load!
Tupsu had a s7 fed from a 4kw supply, something in the Vcore regulator area failed and as a result, 333A @ 12v (4kw or the output of a very nice arc welder) led to to...
