It sounds like your power supply is either not working or is not providing sufficient current. You need 200W (280W if overclocked).

if someone helps me to start it one day gift hosting 
Hi guys I'm new in this forum and I do not know how it works.
I need a hand to start my asic miner cube, I tried it already with two power supplies for computers and the miner will turn on and the fan part, however, one of the green LED is off and the computer does not recognize me.
I went in 2 computer shops but the coach did not know what device it was, the conclusion is that the technician probably my miner is bad because it has tested the power supply and it worked perfectly.
Now I do not know if I trust his opinion since I do not even know who he was and then machine it replaced before I ask someone a bit more experienced than me.
please help me I do not know what to do to get it started.
thanks in advance. greetings. (I'm Italian I'm using google translator, I hope it's understandable)
