So, does this mean that you will only provide support for people using Bitmain(Tm) power supplies for future miners?
Or is this just me being paranoid?
Extremely paranoid

As long as you're not using a 300x 12V rail PSU made by SUPERHIBIGPOWERWOWLED corporation, I'll help out where I can.
Holy shit.. Be careful with these things guys... I'd advise everyone to be careful as hell if you are buying these and make sure you inspect them inside and out.
It has short circuit protection, as it worked in this case. I'm not sure what the point of that drilled hole was, but it will get fixed.
Giving advice about electrical safety when you are not qualified / certified to do so is a crime in the UK (and many other jurisdictions). Latif aka dogie, your only qualification is taking pretty pictures of mining rigs & waffling on about them plus forging education credentials and that does not qualify you give advice about electrical safety. If at all bitmain want to flog these wares, they should get them certified by BSI (or the relevant authorities in respective jusrisdictions) which will itself speak volumes, rather than let users rely on a non electrically qualified fraudster's advice.
