Only use for the BFL PSU is a ready source for the 12v power cable.  Hacked that off, wired to a molex connector, plugged in to the ATX PSU that's powering all the rest of my mining gear.

okay, i come back

These PSU is marked for 120-240VAC. So couldn't be any human fault.

i have two of these china made PSU, the faulty one is leaking current enough to let me feel it passing through my finger, the other one doesnt. If you have a Macbook psu, you will know what i am saying, but it is much more stronger.

it also have a burn plastic smell, I think the capacitor in the ac input had been broken through. Basically it is a low QC PSU an I am not the only victim, i think any user like me should claim BFL for reparation.

I fix broken miners. And make holes in teeth :-)
Any power supply designed for 120v US power will self destruct when plugged into Europe/Honk Kong 220-240v mains after a few hours.

It's probably the self destruction/melting process that created the short.

This is why we have PAT in the UK because shit like this happens. http://www.pat-testing.info/

I wonder why? I've plugged 120 volt devices into the 240 outlets here without problems, makes the power supply a bit more efficient in some cases. Switching mode supplies should not fail.

Edit: Update: I didn't see you were on 240v ring power. That negates my thought on the outlet. Weird, looks like it went to ground, did the jally self-destruct as well?
Odd.

The power supply is shorted internally and passing 120 volts directly to the ring. I'd replace it.

This can happen with non-isolated power supplies. Rare but not impossible.

Also check your outlet, it's possible some yabo wired it backwards so neutral is hot.

If its anything like the PSU I got with my jalapenos, I'm guessing it doesn't have an earth pin, so the transient could register as 120v, but with incredibly low current (as with laptops).

I get that happening quite often when measuring differential between devices powered with separate power supplies, usually it doesn't cause any issues with the devices though. If the machine is still ok, try powering the jalapenos from its 12v line instead and see what happens.

I am sure the PSU is the problem, because i read 13.3V from the DC plug(that's okay).
But i also shocked by outer of the plug.

i know this will happen to some laptop PSU without connect its V- to the earth.

Can any one refer me to a thread that have to same issus?

Theres a few issues with this... The main one being the PSU only supplies about 13v. The second is that you are measuring that from the shield of the usb cable, if active was shorted to the ground something would have completely melted/caught fire.

Check the whole setup very, very carefully.

TODAY IS 1/12, UTC+8

I WOKE UP AND MY HOUSE IS TRIPPED!

I trace back to my PC and it cannot start, i found the problem is the MB

when i was pulling out the cable, i get shocked by the USB cable from both Jalapeno!

now my BITBURNER is also not working, because they are with the same hub!
