I just found out that there are 2 type PSU for L3+

* APW3++ will cost 105 USD
* APW3++ for L3+ will cost 115 USD

The different only the connector, 5 pair (10 connector) and 9 pair (18 connector)

Its cost wise if we choose 9 pair since its could power up 2 L3+ at 220V,
BUT.. i need another view or opinion such as temp, power and effect to the L3+ for long run,

At 220v, each L3+ uses 750 watts (more efficient) and the APW3++ is definitely capable of supporting 100% load 24/7 (unlike consumer grade PSUs). I would highly recommend saving money and going with the 18 connector version if you already have 220v power. We've been running a couple sets in this configuration for months without issue. Total power draw from the wall is 1500w per pair.

Thanks for your review
Any others comment about double L3+ with single bitmain PSU?

So the order of my L3+'s that I was able to get from the mid-October batch was just today marked as "Expired" as it's been 7 days since they released it, even though I sent the wire transfer on the 28th, and uploaded proof the same day. They're going to change the status of my order back to Valid once they receive the transfer today or tomorrow, correct? If my order was just sold with that last small batch they released that was supposed to be unpaid orders... because my transfer didn't go through in time... I'm going to be pissed.

Don't worry, this happens to us every time we do wire transfers and Bitmain always works it out (with the help of a support ticket occasionally). You won't get bumped, but I'd recommend submitting a support ticket now rather than later just to be safe.

Oh you bet I submitted a support ticket, my heart stopped when I read that my order had expired. What makes me even more nervous is that the APW3++'s that I paid for on the same day didn't expire, only my L3+'s, which makes me think they sold my order to that last small batch, and when they receive my payment they're just going to refund me...

I watched your video where you measure the power consumed by an L3+ on 120V and on 220V (240V?) using a Kill-a-watt P3 P4400 power meter.

I tried to do the same thing with my Kill-a-watt P3 P4400 a few years ago. I noticed that on the label it's only rated for up to 125V, and when connected to 240V, it reported the frequency as 30Hz. After seeing that I didn't trust any of the other numbers it reported when connected to a 240V source.

Good catch, I didn't even realize that the P4400 wasn't rated for 240v until someone else mentioned it in the YouTube comments. It appears to work and I've re-tested with a digital clamp meter that is rated up to 400v and got the same results. The frequency does show 30Hz, which makes me wonder how it's able to get the wattage properly. ¯\_(ツ)_/¯

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.

Keep in mind that this PSU mentioned by koljach is not compatible with 120v. The link shows that the AC input ranges from 176v to 264v.

This is good to know for the next overhaul of my farm. I still run the old APW3+ because I ordered from the last batch available for all my miners a pice lol

But knowing that they can really support 2 miner makes it easier in the future to decide if I buy a big or small one.

I don't think the next gen will be under 1kW per miner, but maybe they have a bigger PSU for dual connection as well Cheesy

Well i got out of luck.
Managed to hit the buy it button and was happy to see i had an item in my shopping cart. only 31 minutes later i was able to access my shopping cart to proceed for paiement that for some reason, instead of a L3+ i had the S7 instead (which isn't in stock). I don't understand how it was possible... not a fun experience.
I guess i am not the only one who got screwed by the system.

anyway, probably overkill but it simplifies the whole 'how many power leads do I need" problem

had too many other miners in the past fry stuff....prefer it fry 1 unit at a time not two

That is music to my ears. I'm pretty well convinced bitmain uses some of the enormous profits made off these toasters to pump up price. Hell its no more than 200$ in cost to make these glorified paper weights. Hell wonder how long they mined dash before they decided they were getting to big. Then sell some more toasters prop up price some more which in turn sells more toasters. Rinse repeat. And we all know who wins in the end. Hmmm interesting thing this crypto is turning into! At what point do we decide that this no longer follows satoshi vision and throw all the bitmain controlled coins in the dump. Or have we throw away the ideals that originally made bitcoin attractive for quick profits. I feel I see where this will ehttps://www.youtube.com/watch?v=XxjlJwmICHY&feature=sharend.

kept watching, and a hour later buy button reapeared and managed to get one and get checked out

my first L3+

Now there is a D3 on my wish list lol

Congrats. L3+ units are great. May offer a small tip: If you didn't already, also order their PSU. I initially tried powering using an ATX PSU, it works but ends up needing an ATX PSU costing over 200 USD.

That i worry about. Base on book, the PSU could achieve, but dont know in real run.

a ten buck increase to save an hundreds is very tempting, especially with many units

i have both the above...with some more coming..it don't matter to me

I only use ONE per bitmain miner.....I figure why scrimp and run TWO to a PSU on that model that allows such..at 1600 watt capacity imho that's pushing it

anyway, probably overkill but it simplifies the whole 'how many power leads do I need" problem

had too many other miners in the past fry stuff....prefer it fry 1 unit at a time not two

I just found out that there are 2 type PSU for L3+

* APW3++ will cost 105 USD
* APW3++ for L3+ will cost 115 USD

The different only the connector, 5 pair (10 connector) and 9 pair (18 connector)

Its cost wise if we choose 9 pair since its could power up 2 L3+ at 220V,
BUT.. i need another view or opinion such as temp, power and effect to the L3+ for long run,
