Re: Launching the Antminer L3+, World's Most Powerful and Efficient Litecoin Miner

Hey guys, got one few days ago but wondering something. Earlier in the thread there was talk about power cords and i am not sure what to do.

I got 1600W psu (unfortunately couldnt get my hands on original Bitmain's so had to buy http://apluspower.manufacturer.globalsources.com/si/6008835682132/pdtl/Switching-power/1152345293/1680W-Power-Supply.htm) and 1 antminer l3+. So my question is, will regular cable for computer psu (10A 50-60 hertz) suffice to power up what i have, or will i have to get some stronger cable, and if yes, which one exactly?

Thanks in advance for answers!

2 answers here:
1) L3+ draw is about 750W, so at 120V that's approx 6.5 A, so there is absolutely no problem drawing that from a standard 120V 15A outlet.
2) To be "SAFE", consider that the PSU can draw up to 1680W, which at 120V is 14A. That's right at the limit of the available power from a standard 120V 15V outlet. Consider that most PSU's are rated around 80%, so if you divide 14A by 0.80, you get 17.5A which is overloaded for that circuit.

So, a single L3+ is fine on a 120V 15A circuit, The wattage of the PSU is a max rating, doesn't mean it will actually draw 1680W if the load is only 750W then it will draw 750W and not 1680W.
You could have a 10000W PSU and if the "load" on the PSU is 750W then that's what you will see at the wall outlet (don't forget the 80%, so more like 925W max). Still well within a single standard US circuit limit.

The L3+ only draws 750 on a 205 0r above voltage. It is 800 minimally at 110v.

Ok, then still good for a single L3+ on a standard 120V 15A circuit. The 800W draw along with an 80% efficient PSU is under 8.5A out of a 15A circuit.
