I thought those PSU's were automatic/detect type Huh

Far as I know most are nowadays................ Roll Eyes

Yeah it perfectly clear from the OP but it would appear the power supply is standard ATX PSU. right?

I haven't seen a manually switched ATX power supply in about ten years. Power supply companies hate them because you know some x% will forget to switch it and that just means x% more RMAs.

IF BFL is actually shipping manually switched (god I would hate to see how inefficient those low end pieces of garbage are) power supplies to customers in Europe without either setting them to 110V or putting a warning sticker on the plug connector well that is just sad.

I'm guessing he didn't switch it to 220v before plugging it in.

Did you tell him to? Ah yes, gg.

Our power is 120/220 @ 60 hertz,his power is 120/220 @ 50 hertz.

That's where the problem could be,frequency is lower Cool

Lets see if my answer helped him Cheesy

Frequency does not matter (within reasonable limits) for most switchmode power supplies. Input power is rectified to DC and smoothed by capacitors. Buyer probably just got unlucky and got a bad power supply. If the insides of the little single PSU are any indication, I wouldn't run a regular single from the original power supply either.

I run my little single and other miners from a 750W psu I bought for my GPU bitcoin miner two years ago

So you plugged a 120V item into a 220V line and something went poof?

No he plugged a "voltage auto sensing" power supply sent by BFL in and it went poof.

I know I know its always the customers fault...

Hey, yes I did use the PSU that came with the Unit. It says: Input 110/220V AC 50/60HZ, Output 13V 31A.
I am from Poland and electricity here is is 220volts, 50 Hz AC.
I did use the regular flat pin to EU round pin.
I do not have that kind of regular desktop pc psu :/ if I could get one, what vats should it have?

Hi -

We are working to start shipping soon and have a backlog in the queue, so new pre-orders will likely ship sometime in June, sooner if possible.

Thanks for your patience!

The green line is a very low amperage sense line that, when pulled to ground, turns on the PSU.

That's a perfectly sane way of powering on a computer PSU...

Europe - different power network and burnt power supply unit

Hello, today I have received my 60GH/s unit and I noticed that after connecting it to the european power network via special adapter, my power supply unit got burnt. This is something I wasn't thinking about before and looks like that in my country this is impossible to use these kind of devices.

So, my question is, what can I do with this situation? The Single Unit looks unharm and I would like to ask is it possible to send it back to BFL Company and have my money returned?

This is the advised help from bfl:

looks safe!
