Also, is there anything it can be done to prevent it from going zombie?

Eventually after 2-3 hours it stops hashing.. dunno why..

I don't think you read about these miners as much as you should have before buying

. Zombie is their nature it happens and is a pain and makes it where you have to babysit them.

Other option is automation best one I think is a R1 with CrazyGuy's custom firmware to restart it if there is a zombie.

Also when I asked:
Hot is still not a good thing when talking about power adapters. Is this one that came with U3 or a " 4.5 A" you described once above?

What does more or less mean on that?

well its not exactly like that, but kind of (its a brick but it has a connection like a nice PSU):

I dont know how to upload an image or how to explain it :/

price: 20 euros. i dont know if this will help...

Not sure what your talking about. But the important thing I was asking is it the 4.5 A you mentioned at first?

Or is it the 6A as bitmain specified?

i dont know what are you exactly refering to but i think it is the 4.5 A

Hello...

On bitmain's post about his miner, they specify that the PSU need must have 12 V and 6A.

My question is:

Can i use it with a PSU that gives 4.5 A and 12 V?

THanks

maybe. but not at full speed. or not at all I do not know what type of psu you refer to.

lets go slow. the amp number 6 refers to 120 ac volt input so 6 x 120 = 720 watts ac which in turn converts to about 55 amps dc 12 volts now 55 x 12 = 660watts dc available.

Since an s-3 maxes at 450 watts maybe this why they use those numbers.
since 450 is way less then 660 you should be fine.

You ask about a 4.5 amp psu in such a way I do not know if you are refering to a weak little wall wart that gives 4.5 amps dc.

that will burn like a torch!!

this is a photo of a 4.5 amp wall wart this will not work!

yap, it was actually burning but i changed the default values and underclocked it a little bit and now it gives me like 40 gh instead of 60 but the psu is not hot!

ill search the limit

thanks

I would get a new power brick if one you are using was "burning". It being hot is not a good thing at all, avoid this as much as possible.

It's like playing with fire if it's truly that hot. Eventually your going to have a problem as they should not be "burning".

Maybe i exagerated

At no moment i wasn`t able to touch it

It was hot, but not that much

Just more hot than my laptop`s PSU but less than other ones that i have touched.

On ebay there were a was at least one seller selling U3 power adapters. It might be a little high compared to buying one without bragging run's a U3. Also on forums there was some that sold wires that turn regular PSU's into having multiple adapters on it.

My biggest thing I would warn anyone who talks about U3's. Is make sure you have something in mind for automation. If not babysitting them becomes a pain and is not fun.
