Glad to see this!   Looks great so far!

Cant wait to see more including price  It's already up on site :) - https://bitmaintech.com/productDetail.htm?pid=00020150420021310934XOpI8PEw0689

Whoa!!!


Just about time that a manufacture released a new product.


This miner is going to be BIG!

Since this uses the same chips as the S3. Can the S3 be downclocked to run at a similar efficiency? 0.58J/GH ?


Also I think this should be put in bold

1. The included PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage.


Pretty much has no market in North America then.

Looks like the board design and PSU guys did all the work, and ASIC guys sat this one out. Interesting set of choices. They must have ordered a bunch of BM1382 parts. The yields on those must be pretty good.

Did I miss the price in this announcement, or is that only available on the ordering page?

ANTMINER S4+
Speed:    2570GH/s
Weight:    14.4 kg
Price:       946 USD ( 4.206 BTC )

we returned to an older chip, added a +, and the price always very high, congratulations

For the same price, you can have 3xS5, more efficient and hashing at 3400-3500 GH.
Bad timing to release this one, or the price should be dropped under 640$.

S2 upgrade kits with BM1384 would have been better right now, or some kind of S6.

Antminer S5: $340 for 1155 Ghash, which is $294 per Thash at 0.51W/Ghash

New Antminer S4+: $946 for 2570 Ghash, which is $368 per Thash at 0.58W/Ghash


What am I missing? New miner is released which is less efficient but the price per Ghash is higher? The difference is more then $70 per Thash, definetly not worth the PSU you get with it...

You can always use any server PSU, and this one (stock PSU) - sold it to someone who need it or try to ask Bitmain to ship S4 without PSU. I would prefer to buy it without PSU in any case (less shipping price, more freedom to choose reliable and powerful PSU for overclocking).

But with such a price, with such a BTC price, I have serious doubts that I will buy it ever...

I think these s4 + I lower the price I are all in stock

You will need to provide a PSU for each or both those S5...


Yeah... We are still waiting while Bitmain keep silence... And may be they will continue to keep silence since S4+ should be sold...

I agree with you, a DPS2000BB with fans and breakout board will cost roughly 100$, can power 3x S5 and can be used with your next gen miner.

bitmain should send fans of silent to all customers who have purchased s5 with infernal noise

but then again the Chinese by nature and very greedy for money, and with style are born, not made with money lords

I am really disappointed

S4+ is very noisy, and not suitable to mine at home. While S4+ is working with US industrial electrical standard.
 

The reason why its more expensive then a couple of S5's is because it has the PSU included. And its almost as efficient as an S5.

An 1500W PSU is what? At least $200-250 ?

So price seems about right.

I think that is a little bit unfair.  It won't be a miner that you would put in your front room sure.

But some home miners are lucky.  I know I am working on a summer mining area.  Pretty much let me start from scratch and do what I wanted.  I will have at least 1 220 in it for fun.

Many could easily add 220 for mining.  Sure it is not as convenient as 110 for many.

The S4+ is 13.7% less efficient then the S5 if you compare the W/Ghash.

2570 Ghash of S5 miners: $340 / 1155Ghash * 2570Ghash = $756.54

2570 Ghash of the S4+ miner: $946 * 1.137 (Efficiency difference) = $1075.60


Price difference with the Efficiency difference included: $319.06
That is quite an overpriced PSU then, and the extra weight the S4+ has will make shipping more expensive aswell :)

So much for a new miner... Hooray!

With this high price it is not interesting.

I love you Bitmain....

Whaaaaaaaat?  Do you know what a TWO POLL BREAKER IS?  220 to 240 volts, depending on your configuration.

No need for prejudice...

I do not understand why a return to the old chip, instead of going forward we go back? the price should be much lower, however, and very high, you have created
s5 with noisy fans, and do not even bother to correct the problem to help you, I'm sorry for you, but I've already had a bad experience with you to bitmain, you made me pay 3 shipments x 4 x antminer s5, including 1 s5 was well used, I have not even refunded the cost of your mistake, not even 1 coupon for the next purchase, that will never happen again, because you are only interested in money, and does not meet the customer.

Bitmain, any chance you'll release an upgrade kit for existing S4s? Those of us that are using upgraded PSUs could easily swap the old board with the new ones.

what will make them pay for the upgrade kit? 500$????????? ???

Someone wrote in another thread that bitmain can sell individual parts for current miners.
It may be an option to "make" your own upgrade kit.

as I said we need to see the costs

but fail to produce a car from 10 terash
to 16 nm? the cost $ 1500? :)

I also love this product.  I won't be buying it but it delays the s-7 and the s-6 I  am hoping for these to stick around for 2 or 3 months.  Then the s-7 comes out in aug.  

This will keep difficulty growing very slowly which is good. At bitmaintech very smart choice for right now.  I am also willing to do a long testing of a demo.   I recently put in not 1 but 2 240 volt  lines.

I would really like to explore the ability to underclock and quiet this machine.  Good product choice.


AT all miners my self included.  We are not seeing .3 watt at the wall gear in the near future.  You smartest move is finding  at least 8 cent power and threading water for a while

Bitmain where are the S2 upgrade kits?

Why is an S4+ which is less efficient and costs significantly more to ship than an S5, considerably more expensive per GH?

A rack mount case and psu don't warrant the difference in price.  It is hard to see this as anything but a ploy to use up old chips.

Due to these factors the S4+ should be priced at no more than 1.1x the cost of ( 2x S5 ); and this is placing a lot of value on the psu. 

Pricing on this model at current exchange value would be ~ $748.

All customers who purchased an S4 should receive 1x coupon per S4 purchased.  A real coupon; not 100x spam BS coupons.

Until now, I have bought every product Bitmain has ever made; but I will not buy an S4+ at this ridiculous pricing. 

Remember shipping to North America is going to be at least $140 on top of the purchase price.

On a positive note, I don't mind the removal of the lcd, and moving the power connector to the front is an improvement.

Yawn. Miners this efficient were available over 8 months ago.

I don't understand why Bitmain would waste time and money updating the S4. What a waste.

Awesome . I loved the design of the S4  its compact and none of the wires all over the place.  Going to get me one .

I don't understand why this exists as a "new product" given that the S5's are more efficient and economical.

 




 They had the chips available it was easy to do.
 This is actually good for miners with 205 volts and low power costs.
 If you are not in this group then it is worthless to you.
 Like myself you need the s-6 or s-7

Exactly.  Why .  Why.  Why!  Because their new stuff won't be available till mid/end summer.  Bitmain milk it for all you can.  The specs just aren't there.  Should have been sold has kit.  Notice I didn't say uprade kit.

Once again we don't need more miners or even better miners.  We need higher btc prices.   

BITMAIN what is the ambient operating temperature range for this miner?
thx!

I think you smacked the proverbial nail straight on the head there! Though I still question why they went through the design process for the S4+ (they look to have flipped the chips like they did with the S5), I suppose since the S3+ (sold only in China) was already about, they deemed it feasible to milk the last ounce out of their older chip seeing they were rushed to market with the BM1384 (S5) chip.

On the whole, that would be understandable, but then the pricing at that efficiency (compared to an existing and available S5) is mind boggling. I can not think of bitmain caring more about the network (and diff rises et al) more than their bottom line. On the face of it, the dev costs for the S4+ are down the pan as no one in their right mind would buy the S4+ out of China! So that leaves the option that this was built (and is being targeted) for their hosting service! Neat trick there bitmain, but it will only come off if the power costs borne by the user are at or less than 8 US cents.

Saying that, the S2 upgrade kits must be a matter of logistics now .... surely!

I agree old chips come on get with the new tech chips bitmain. All I have to do is buy another S5  and I will have more speed than the S4+ !!!!!!

and Still running on 120v to !


Is this your Idea of a joke or are you just milking the cow or you trying to get rid of all your old stock.

also I don't have 220v all I have is 120v single phase 50a service so I could not even use the S4+.

Ridiculous come on bitmain new chips please!!!!!

Or could be they don't have the funding to make them they are going to milk the cow and then Disappear never to be heard from again !


  

Italy we have 220 volts, but I never buy s4 +, price too high,Shipping to Italy high, and high customs fees, praticamento s4 + I pay for 2 times

Thank you all for all the input so far.  If you are visiting New York between April 27-29, one of the S4+ will be displayed at the Inside Bitcoin Conference.  Please stop by and say Hi.  (We are also thinking about having a local Bitcoin Tax specialist at our booth to answer questions regarding mining and tax in USA. *)

Here are some preview from the S4+. 

Noise wise, this is measured with a smartphone app.  So it could be a few +-% off.  Its not measured in the non-echo room.  Room with Drywall as the wall material.

*Tax Advisor will be a third party advisor and not from Bitmain.

^^ Looks good but damn 96 Db haha More targetted for datacenter operations than home miners except the I do not think than an upgrade for most large scale applications is an option at this point due to the price per unit for the S4+.

And a case made for an LCD screen but one does not come with it.

more noise than s5, change fan

New chips New Chips New chips New chips Come on already Bitmain !!!!!


Also its says p2p.antpool.com the link is dead Just like the s4+

or bitmain is going to be without new low power chips !!!

Looks like nice gear.  I am hoping to hear from new owners of it in the future.

As always many complaints on price.  Remember the s-2 and the s-4  had many complaints.

 What is shipping for this to the usa?

Okay I went on site this is :

4.22 btc    or   946 usd

0.558 btc  or    125 usd UPS shipping

4.778 btc  or 1071 usd

That one is far beyond OUR control. 

yeah  btc price is not easy and as for what to buy 1071 for this new gear vs 1118 for 3 s-5's

you get 2600gh for the s4+ and a free psu  giving about 1500 watts
you get 3450gh for the s5    and you need   about  2000 watts worth of psu you supply.

prices are close if you do not own a psu. the s4+ could be better for you.

Good point... I forgot to take into account the external PSU costs with the S5. That does slightly even out cost comparison.

Well since these are screamers as are s-5's  you could go server psu and run 2 s-5s for under 120 in psu cost.

so 1071 vs 1238.

  make it 1075 vs 1250

 the s4+ is better built case wise.  if they both were exactly   .52 watts a gh

  I would call it really tight,but the s4+ is .58 watts. So point goes to the s-5.

Which has always been the case that :

the s-1 = better $ deal then s-2
the s-3 = better $ deal then the s-4

Now:
the s-5 = better $ deal the the s-4+

I could argue that buying a 3 pack from ehash avalon 4.1 is better then buying the  s4+ if you have a psu on hand

S4+
lets see price 1075
hash              2600
psu free
really fucking loud.

Avalon 4.1 3 pack
lets see price 1600
hash             3450
if you have psu free
quiet

So 3 S'5s cost 4.985 BTC including shipping and 1 S4+ costs 4.772 BTC with shipping. I really do not understand Bitmain sometimes... So basically for .213 BTC you can get almost 1 TH/s more hashing for a couple hundred extra watts.

Who doesn't have spare PSU's sitting around after BTC mining? I think I have 5 just doing nothing. Quit including these stupid ass PSU's that just jack up the cost.

If I was going to buy anything from Bitmain, it would be 3 S5's. As it is now, I guess I will continue to wait.

	Price	PSU	Shipping	$ Total	Watts	Gh/s
S5(2)	680	60	86	826	1180	2310
S4+	946	0	150	1096	1500	2570

There's a compelling table why the S4+ is a no go when the S5 is still available. All values are in USD for shipping to the UK. The PSU prices I've factored in for the S5's are four 550W Server PSU's including the braces (I can get 4 of them for GBP 5 each off ebay).

EDIT: Bear in mind that on top of that, I'll have to pay VAT @ 20% on the CIF price of each, so ~ $220 on the S4+ and  ~$165 on the S5's.

I went for peace and quiet I have a few avalon's 4.1's

The only thing sadder than this product is the fact that people will still buy it.

If anyone is interested, there is a 360 degree view available here (http://www.dogiecoin.com/bitmain-antminer-s4---360-degree-view.html). [14MB warning!]

Yuck, this price-per-performance is hugely disappointing.

BITMAIN, it is really good job! String design is the key, dropping efficiency from 0.69 to 0.58 at the same freq, awesome!!!!

For everyone who is crying for the price and older chip design, please keep on mind, that professional miners need easy set-up and easy maintenance design. It is very expensive to deploy huge farm with many small miners with separate PSUs and cables, etc. It is cheaper to buy more expensive miners with less work for set-up. Also maintenance is more expensive for more smaller miners.

Please keep also on mind, that datacenter grade miners are not adjusting frequency or doing any other tuning, it cost also a lot of money and takes another unpredictable results for business projections.

I am home miner with less than 25THash, so I will buy S5.

Even at 5c power and no import taxes, it's 250 days to break even, at 10c it's over a year, not much point adding the figures for the UK :)

https://i.imgur.com/bLnnzTY.png

So then why Are you stating all that stuff then just for publicity.

I have 12.6c with residential UK power, so not that far off for me :P Although I appreciate the majority of the country only has access to 14-18c.

The expected specs. released by Bitmain for the S2 upgrade kits @ >.4w per gh were indeed hopeful.  I assumed the S4+ would have been comparable.  Seems they rushed this out with little thought of who'd buy it.  They patched the psu problem with a bandaid (205v + only) and made a new record as the noisiest miner to date.  Clearly they don't listen to the public and will go the way of Bitfury and KNC to produce their own product.

Its an entirely different PSU, and while high voltage only isn't desired its also not unreasonable. Anyone running larger equipment like this should really be on 220V anyway.

nice price compared to the older S4, 946 + shipping   well worth it,  but the noise at 70 db . id have to turn  it off at nite and 220 v which is np for me, its clearly meant for a data center .

Neither sound or power is a issue for me.   I am working on making a area just for mining.  I'm hoping to have it done in next week or two.

I think it's interesting this is using 220 v.   I think it shows promise for future releases aswell.    Going to 220 allows a lot more hash and options on releases.

That may be true but reducing the overall power / gh @ .58 wasn't a huge change.  If they would have used their 1384 chip we would have possibly  stayed on 110/120 and had better efficiency.  Understandable the larger rigs should be on 220/240 but Bitmain just didn't do much homework on this release.

With 220/240 it opens them up to even bigger rigs in future.  I think it was a good move overall.   

I still think 110/120 has a spot aswell.  There will always be some home miners that will be stuck with this.   So I don't think it will go away. 

Outside of the slightly (marginally) better power consumption, what's the point of this product? You can reach 2.5 TH/s with a regular S4 at half the price and without need for 210 volt power. I have to say that I don't understand at all why they spent the time to even design this miner.

So I sold 2 S4s today locally for a very good price, and ordered 2 S4+ to replace them with. Very cheap upgrade after selling them.

Placed the order this morning, and I just got shipping notification. If there's something bitmain can't be faulted for, it's shipping on or ahead of time.

I never got an S5 or had much interest in it, so I can't say I know anything about these string setups for chips vs dc2dc. Is there a good explanation anywhere? I'd like to understand how the S4+ runs at the same frequency as the S4 (200Mhz) with 44 extra chips and manages to consume approximately the same wattage.

That's simply not true. An S4 at 2500gh/s steady average will be consuming more than a 20A 120V circuit can handle. Half the price? Are you factoring in the 2x ~200$ power supplies you'll need to pull that off? (assuming you're original psu is dead since it likely is or will be in short order )

It is not as terrible as some people think,but it is very much more a specialty miner.

Like the Avalon 4.1  where you pay a lot for quiet running. A different quality but a premium none the less.

I had:
 sp20's
s-5's
 avalon 4.1's

If I was single and lived alone I would have kept my sp20's
But married and sharing my house with the wife I kept avalon 4.1's

Looks to me  like the s4+ works on a real farm in a barn.

Many USA farms have land so noise has no worries.  Most farms have a spare shed or out building.

 S-5's would not be the best choice for that.  These would be good due to the case.

 Also it may turn out that a better psu with plat 92-94% could be sourced.  Some 2000 watters are around and even the massive 2880 watter could work.

2 s4+ on 1 240 30 amp circuit using the 2880 watt psu from finksy

 https://bitcointalk.org/index.php?topic=966135.0

could bring down that .58 watts per gh to  .55 watts per gh.

making these more attractive.

Thank you for the mention Phillip, but the breakout board is J4bberwock's, I'm only helping him with North American sales and can't take any of the credit for his hard work.

Any PSU going from 120V to 240V will gain 1-2% in efficiency at any rating, there is just no reason for miners not to do it if they have the ability to.  240V also allows most server PSU's to run at higher wattage, and is required for the 2000W & up PSU's.

That being said, going with a 2880W PSU which can power 5x S5's with 80+ platinum starts to look a whole lot more attractive both efficiency and economically-wise than the S4+ when you run the numbers.  You are definitely paying for convenience with this type of package, just like the S2 & S4 before it.

I have to agree that 5x 1150 = 5750gh  for the  s-5's

and 2 x 2600 = 5200gh for the s-4+    the s-5 setup is the winner.

  but the solid cases are nice  and if you have the 2880 watt psu along with 2 s4+ units in an out building it could be worthwhile to do.

For sure this s4+ is not for most of us.

for what it is - its at least an available industrial racking unit. noone wants to install 100 S5 units when they can just do less than half as many of these, and not worry about extrenal PSUs (which requires careful stacking or shelves)

The price isnt ideal, but theres no other offerings that make sense for a larger buyer. The best value comparison would be the SP30 (can run between 3.5TH/1.8kW & 4.5TH/2.6kW). Its 2U racksize, with a pair or NAMEBRAND swappable 1200W PSUs. Pretty fair comparison, if not a better product based on stats.

They go for $1350-1600 USD *shipped* used right now.

With its high voltage requirements, noise, and cost for lower quantities, clearly this model is geared toward farms (as well as clearing out Bitmain inventory, of course). But if I was setting up a farm, I'd have concerns.

The S4+ requires a minimum of 205 volt power. Lot's of US data centers offer 208 volt power. Is a 3 volt delta enough to reliably run these at 208?

This is a string design, which means no clocking options right? I get that the string design is cheaper and that farm deployers are less interested in tuning. But I'd still be concerned about resale once these are effectively used up and down clocking is not an option. Maybe farm operators just throw older miners away after they cross the profit line?

I have access to a data center with enough space and power budget to deploy one of these. But factor in the price for small quantities and this is a non-starter for me.

I'll stick with my SP20 (which has already ROI'd) until the next more efficient hardware comes out. It's kind of nice to be counting up profits rather than counting down the days to ROI anyway ;)

I think a lot of small scale miners are in the same boat. The first company to come out with something really new that has a chance of an ROI will sweep up everyone who's currently in a holding pattern. Hopefully mining manufacturers see this as an opportunity and will not just focus future efforts on the farm market.

@bitmain

Can you tell me about the Capacitors on this????  I am looking at cheating and moving your product to a full immersion mineral oil bath.

The only issues I've ever had with Mineral oil cooling is when cheap Capacitors are used, and they plastic swells and bursts from the mineral oil.

I'll have some 6K pictures either today or tomorrow of internals.

Thank you!

Not sure how to feel about this one.
No LCD, no beepers, not North American home friendly, grossly overpriced.
Definitely not going to make friends on this one but yet again, no 3U miner is good for home mining to begin with.
Mainly because people do no properly ventilate nor cool them which is what makes them loud as hell.
Those things in the winter are as silent as a purring kitty or a cool S3.
I have one S4 and it is not running full blast, it's properly ventilated.

Looks more like a data-center ready unit...
Yay for them but with the price of Bitcoin the way it is, not such a wise investment.
Oh well, like in anything, one man's trash is another man's treasure.
Now I regret selling my S3's... those things are marvelous.
I also regret not buying more C1's.

About 1/3rd of the pictures are processed No caps anywhere on the hashing board and none that I could see on the controller either. Cables on the non PCI-E version of the PSU are very long so this should be good to dunk.

Only just got my unit started on the testing rack so a full review will be some time, but surprised with the noise. I thought the 40mm PSU fan was going to be an issue but its inaudible over the main fans. That means noise levels appear identical to the S4 above 25C, and slightly louder above as it runs hotter.

I like conspiracy theories but not when it messes with your financial choices.  It's not hard to believe the push for new miner specs to only be run from a farm setting.  With the added cost of shipping makes it real good for Bitmain to have your miner with them.  Just thinking out loud.  I for one don't support large farms.  Capitalism at it's best!

1 thing for this S4+ is, it is a new PSU different from the previous S4 version.  It is stable on 208v.

if you like the rack mount system, you will definitely like this unit. 

Also, not like S4, this unit does not require human interaction with the switch on the back during the power cycle.  When the power comes on, it will boots right up!

Just had a negative growth and it may be another negative growth in about 12 days YAY!!!

Bitmain,

I assume air intake is on the front of the unit, where you plug the PSU? Is it OK to reverse the airflow by switching all 4 fans around? I need the front to be the exhaust side.

Air intake is from the front (PSU/Ethernet port side)  THere are 4 fan connectors on the control PCB!  ;)

Always the policy is any modification of the unit will void the warranty...

side note, reversing the fans should not do any damage.  2 fans to intake and 2 fans to suck them out of the box.

I was hoping it wouldn't void the warranty since it's such a minor thing. Bitmain had us switching PSUs and fans constantly with the S4, even hash board occasionally. Surely just reversing the fans should be allowable without voiding the warranty?

I could be missing something but why not just turn entire unit around, instead of reversing fans?

He needs the power plug  to be in a certain position.  I am assuming that all other power plugs on all his gear  are the  outake side.

Yeah, that's the more logical thing to do. With the S4s I reversed the fans so I could still see the LCD screen, but there's no screen this time around.

In my case it's mostly about having airflow where it needs to go while still having access to the front of the units. This pic will give you an idea with some of the rigs:

Wouldn't want all that hot air stagnating in back of them, exhaust needs to come out of the front where it's then extracted via a large fan to the exterior.

I really like your setup.  After rereading my suggestion I just want to say I did not mean as an insult.   It possibly could have been taken badly.  I was meant as a suggestion not insult.

Thanks :) That's in my detached garage at home, which only has 60A to work with. What's in that picture is taking it all up, so I still have a lot of hardware in the house that needs to be moved out there once my dedicated 200A electrical entrance is installed hopefully in the next 2 weeks or so. Hardware not pictured: 2X Neptunes, a Titan, a 90MH A2 Terminator, 2x S4 and as of Thursday 2x S4+.

I didn't see it as insulting at all, it would be the most logical thing to do really... I just like complicating my life for nothing, so I reversed the fans in the S4s and the Alcheminer to suit my "needs".

And just think, after Thursday you can stop complaining about those "noisy SP20's", since the new S4+ will completely drown them out!  ;)

I am glad I don't get your electric bill each month. What's your electricity cost if you don't mind the inquiry?

Heh, I run the SP20s at 100% fan and don't hear them thanks to the 2880w PSUs. they're pretty much all I hear, in fact. Doubt the S4+ will be louder than they are!

I pay about 7c/kWh USD. In Canadian funny money, that's $0.086.

I've got an S4+ sitting next to an S4, identical fans and identical noise. The PSU fan isn't a factor. So the S4+ is loud but its nothing we haven't experienced before.

No Fans no noise..... :)

This is a no brainer... This is what the s4 should have been...

To release this now with old chips, Shame on u bitmain.. Seems like u have excess stock in your warehouse of maybe C1's and ur trying to get rid of the chips in bulk..

To high a price with S5's in circulation, To high Wattage, To much noise.

I was looking forward to an S4+ using the newer S5 chip at least at 1500w at least that would have pushed it over the 3th mark..

Bad rushed decisions... Come on bitmain, U were the best at this & now your slowly starting to run downhill at a very quick pace & u still havent fixed the voltage settings on the S4

Heres a tip for the S4 in the Freq table take out all the over clock settings & lock them down but leave the underclock settings..

Then in the voltage settings put a drop down box with the underclock voltage settings with suggested freq settings so that people cant blow these things up.. But can downclock them.

Then also put a box allowing the  --bitmain-homemode or normal mode so that can be run a little quieter.

END OF LINE

Sometimes for the miner, the best strategy is to run the miners that already in hands and not to buy any new miners. Only buy the miners that is best for you. For a home miner the electricity cost is high and noise is a pain, so we should buy the high efficiency mining rigs. But for large scale miners, the cost of electricity maybe low and noise level is not a concern, they may have better tolerence with the old chips and not so sexy power efficiency. 

Was the above meant for me?? The S4+ is no good for no one...

Why use old chips when new one are available that are faster & more efficient??

Leftover old stock by the sounds & if this is the case they should have sold all of them before releasing new ones.. This is bad business practice that smacks of greed!

So I just convinced my Wife  to sell our home in NJ and move out to the state of WASHINGTON.
We are both retired have pensions. I found a 15 acre place with a barn that had a large 200amp 240 watt service in it since the prior owner had a welding business.

 Power is 4 cents.  200 amp 240 means 48kwatts x 80% = 38 kwatts,

 I can fit 25 of these . they would be far easier to  manage then s-5's the bold is how they could work for me if the example was true.

So basically these are for low power cost farms and data centers.  Not no one. As you think.

But I agree with one thing they are forcing a guy like me out of the game Since I do not have the ability to keep the noise controlled.

Would a step-up transformer work to power one of these units from a standard 120V connection?

Something like this:

Nice one Phil ! Can I rent a room now ?

Just kidding ;-)

I would not mind moving to washington since my wife and I do have pensions and are retired.  But all of our families are east coast so we will stay on the atlantic vs the pacific .

So you moved to eastern Washington?  Someday I will retire there..  it's beautiful and peaceful.

Wow cogratz on such a big move.  That will be huge on your mining profits.    I look foward to see what you have in store!

The price is too high....its cheaper to buy a few S5  ???

LOL... that must have been an interesting conversation.

Phil - Honey, I think we've been in NJ long enough.  Let's sell our house.
Wife - Where did you have in mind?
Phil - Well, I was thinking about Washington.
Wife - Oh, Seattle is a beautiful city...
Phil - Ummm... no, I was thinking more like eastern Washington.
Wife - Huh?  There's nothing there!
Phil - Sure there is!  Spokane is the second largest city.  There's the Columbia river, the Grand Coulee Dam... we'll save a ton on power costs!
Wife - Alright, but the weather is nasty.  Hot summers, freezing winters...
Phil - Yeah!  Those freezing cold winters will be GREAT!
Wife - You hate the cold... what are you getting at?
Phil - Well, I found a nice place on 15 acres with a barn...
Wife - A barn??!!??  Why would we ever need a barn?  We don't own horses...
Phil - The barn used to house a welding shop...
Wife - So?
Phil - So, it's got a nice 200 amp service with 240V power...
Wife - And?  You're going to start welding stuff?
Phil - Well, no... not exactly.  I was thinking it would be a great place to put more of those Bitcoin miners.
Wife - Bitcoin miners.
Phil - Yeah, you know...
Wife - You want to move us across the country... and your reason is so you can have even MORE of those damn noisy miners?
Phil - Ummm.... yes?

Please note, the above is a completely fictional account of the conversation between Phil and his wife.  I was bored and thought maybe it might elicit a few chuckles.

In all seriousness, congrats, Phil!  I hope you and the wife enjoy your new adventures :).

PS - can you host a couple miners for me? :P

Hahahahahahah !! :P

Quoted for future laughs.

Most of the huge farms are in and around Moses Lake area, more central Wash. if you go by a map.  But Washingtonians call anything east of the Cascades eastern Wash..  Spokane's energy costs I'm not sure of but is about 2 hours away from Moses Lake.  Off topic I'm sorry.

When I first saw this, I was thinking dmwardjr, and not Phil. Personally, my wife would just wave as she sent me on my way, alone, to Washington. Yes, I make adjustments for mining. Moving from Minnesota will NOT be one of them.

color me confused. One message says that Phil is going to washington to a 15acre estate.
the very next message says that he stays on atlantic.
I guess it is still under discussion.

Anyway, I also want to move to WA or OR myself, but it has nothing to do with mining, nothing at all  ;D
However, most likely, I won't because it is difficult to convince the "nest builder" to build a brand new nest somewhere else when the current one "just started to look good".

While the device you show, might be able to produce 240V, there are some serious, un-mentioned caveats:

- You almost certainly need to have the two 120V outlets on different circuits. That doesn't just mean two different outlets on the wall, but different circuits. You would have to figure that out for your house.

- There will be an ongoing efficiency cost, on trying to do this. In order to get 2000 Watts out on the 240V outlet, you will almost certainly need 1050 Watts for each of the 120V lines (total 2100W or more).

- There is also no mention of how well suited this kind of a device is for 24 hours per day operation. I'd be surprised if it didn't generate some heat itself, and run the risk of failure.

So while might be theoretically possible, I doubt if it would be practical, or cost efficient to do so.

Depending on your personal family situation, would you save lots of money on electricity, only to hand it over to an airline for trips "back home" to visit family? Unlike some folks, I am unwilling to chase Bitcoin across the country. Just my personal choice though.

 It was meant to be a joke.  I am In NJ for 3-4 years.  Then Virginia.



That conversion box may be okay to run 1 s4+ 24/7    it could be 95% efficient and if you read it closely it has de rate numbers for runs longer then 3 hours.  the weakest one  reads

The unit supplies anywhere from 216 to 250 Volts of AC power through two NEMA 6-15R outlets at 15 Amps for up to 3 hours or 12 Amps for longer periods, thought it has a momentary over range capacity for starting motors and similarly demanding devices.

the new s4+ needs 1600-1800 watts that is 7 x 240 = 1680  so at most 8 or 9 amps constant . but the cost is more then it is to hook up a 240 volt line.

Now if you are in an apartment and the noise means nothing and the power is free. yeah it may be good.  remember it reads  the 2 different sockets must be out of phase to work.

The A220-15D voltage converter uses two 72-inch power cords with straight-blade, US/Canadian standard, NEMA 5-15 plugs plugged into two out-of-phase, standard 110/120 Volt outlets for power input.
..
you may not have access to that in your apartment.

Phil,

So, this means you are not moving to Washington?  It was a joke?

When i said these are no good for no one... I was meaning no good for people who currently own S4's..

Anyone who missed getting an S4 these are good & easy to manage but S5's would be better & cheaper to run.
