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

[bigmaq]

Anyone tried these: http://www.ebay.co.uk/itm/Power-Supply-for-Two-x2-Antminer-L3-with-Complete-PCI-e-Wiring-Installed-/182298369039?epid=2142838835&hash=item2a71d45c0f:g:scUAAOSwmfhX7qvz

Hey guys,

I ordered 3 Antminer L3+ and 2 APW3++. On their description it says 1 APW3++ can power two antminers L3+ given that your voltage is 220V. I sent them a message to confirm this and they told me "no it can only power 1 antminer L3+". After some back and forth emailing she gave me the impression she didn't know a lot about the products. Has anyone ordered any APW3++? can each of them power two antminers?

Thanks!

If it's connected to 220V and have 18 PCIe connectors interface type, Yes! It can power 2 L3+... She is confused because of the version for sale right now (with 10 PCIe connectors).

Is it a good idea to power 2 L3+ (800W each) with a 1600W PSU?

exactly my thoughts, seems kind of sketchy running a cheap foreign made PSU at 100% or more -- I wouldn't do it

How long before some dummy overclocks them and starts drawing more than 1600w.

Sounds like a recipe for disaster

Did you even read my post above about this PSU case?

Also I wouldn't call them cheaply made, APW3 psu's have been quite reliable and got some good parts inside if you have a look inside.

If it's an ATX PSU the answer is: NO. If it's a bitmain/server PSU the answer is: maybe (but not recommended to run 24/7).

Experience tells me you don't try to pull 1600w through a 1600w PSU on a 24/7 basis and I don't care if it is a server PSU.  When I spec servers I NEVER spec a machine that is going to draw the max the PSU can supply even if I am working with redundant power supplies.  You just don't do it when you spec out your servers so I see no reason I would do it with a miner.  Frankly I would have to look, but I bet my servers don't get hit has hard consistently as these miners do on a 24/7 basis.

So spec out a PSU and run it at 100% 24/7?  I just won't do it.  These PSU's compared to buying a PC PSU is really affordable.  Why risk damage, fire, or injury for something as inexpensive as these PSU's?  One miner, one PSU and call it good.  Just my 2 satoshi...

Like HagssFIN said... Bitmain's PSUs are very well made. It's not a "cheap foreign made PSU".

I agree... I'd not run it above 80% 24/7 in any scenario (even with Bitmain's or server PSU). 1 miner/PSU is the way to go.

Like I said someone going to overclock them 10-20%, I'd just go with one per each psu

main reason I didn't go with it is I run the rear fan at 100% off the psu and can't do that with these bitmain psu's that I am aware of

If you haven't noticed the L3+ fan controller is buggy. I happened to catch them overheating while both fan rpms showing zero, sure they reset but they reset into the same buggy state -- over & over until the board burns up -- saw it happen a couple times, once on auto fan control another  time on 75% -- so you can have your cheap bitmain psu's feeding their buggy bitmain fan controller.

oh by time the board actually shuts down & resets the temp is actually over 120c, so  the 80c cutoff doesn't do much, it's not an instantaneous shut down and it's not a failsafe

a few of those cycles and your board will be shot

Thanks for collaboration with your experience. It's always good to have a realistic point of view of who are already running L3+/PSU.
Is anyone here already using the APW3++?

Hey guys,

I wanted to ask if the antminers L3+ genereate a lot of heat? I live in the Middle East and I have 3 miners coming at the end of August. Here the electricity is quite cheap (.06 USD/kw-hour) ,but it's hot as hell so I think I would need to keep them cool with Air Conditioning. Do you guys think that's possible? or is it a losing battle?

[Ryancope123]

Do you guys have any reply from Bitmain Support lately?


I ordered some L3+ from July Batch with PSU (shipping 10 days after payment) and I have not received the PSU yet. If they send it together fair enough, but a day after I bought the PSU was "sold out" and now the new one arrived. I am not sure What to think after it clearly stated shipping within 10 days....



I contacted Bitmain 2 times in the last 10 days and I have not received ANY reply...   


Does anyone have the same problems?

I am exactly the same !!

Contacted bitmain and the guy didn't understand what i was actually saying to him, the fact the PSU should have been here like 2 months ago....

[kodokbuduk]

i have no problem with couple apw3 1600 psu (previous model) i bought before sold out, usually they sent 3 days after completed payments (first notification item was picked up and then 2nd notification item sent with invoice attached in pdf file)

So you received your PSU you ordered lately?

With this many machines being sold and everyone trying to jump in mining ltc, how long do you guys think would l3+ still be profitable?

I will be ordering 2 from the next batch, which probably will ship by the end of september, and planning to increase the number of miners up to 30 with the revenue I make. Only after then I will be converting my coins to usd... But does anyone have a speculation of if this plan is viable?

A few weeks back, L3+ made a profit over $1K per month and now it already is around $950... That is somewhat disappointing but of course, expected.

Even after owning 30 miners, my revenue might be below $20K per month if it goes down this fast I guess. I actually might never get to 30 miners with difficulty rising so fast

So, what do you guys think?

Don't know when you checked the calc, but I get 1,310.07   Dollar a month

Well even that is above 950, and only because the exchange rate dropped a little.  But to make it short, no-one knows if its worth it or not. I would love to know how it will be 3-5 months from now.



And BTW the power consumption is 880W
