Re: 28nm ** 1T ** 900W【JingTian miner】 in production !!!

Got it. It's a monstrosity with 3 external power supplies that I have to wire in myself... however even the power side needs to be screwed in with bare wires, and that's basically illegal to do in my country unless you're a certified A grade electrician... so I'm not sure exactly what to do with it yet Undecided

External power supplies?? Got a picture?

It's as per the opening post, but with one extra power supply (presumably a spare/redundancy). Here's some photos, including a baseball cap for size comparison:

Uggh.. wouldn't be an issue for me to wire it up here in the UK but I thought it was gonna look more like the Dragon miners (massive black box with two ATX PSUs) like bobsag got.

Sure it's easy to wire up. But it's also illegal to do mains wiring yourself here. PSUs would have been much simpler, but in fact these are much higher quality and more expensive than regular PSUs.

So a non-standard PSU, do they have any recognised compliance marks?

It would not be a simple matter of calling an electrician to wire the machine to mains if there are no compliance marks.
