Topic: ANTMINER S5+ is available to order, 7.722TH/S 0.445J/GH - page 14. (Read 40193 times)

not sure if your missing the point or just trolling i ordered OLD s5's before the new S5+ was released and i would like to change my order...... i think it pretty reasonable since they haven't shipped my order and it would be very easy to do

S5+ is today  2341 USD

Friday, it was the price  2375 USD

Should I now cancel the order of Friday and today to make a new order 

Yeah i emailed them about it and this is the response i received

"Hi,
Sorry, we're arranging the shipment of S5 very soon and the order has been confirmed by financial team, we cannot change it any more.
Thanks for the understanding.

Best Regards"


IE the order has not shipped yet but fuck you we won't change your order as we already have your money.

not great for a company you just spent 2500 usd with.

they are not about customer service I have contacted them multiple times on an RMA for 2 crappy U3's I have that burnt out and they wont RMA them for me because I purchased them through a reseller and not directly from them because they had a minimum order of 20 units and who the hell wants 20 of those? They are crap they freeze all the time and generate like 20% errors for me

i placed an order for 6 x antminer s5's 1 day before the s5+ was released and paid in full, now  the bitmaintech support wont let me transfer my funds to a new order and pay the remaining difference to receive the s5+....not very pleased.

No. THey write:

Contract Suspension
If after 120 days, a PACMiC has still not recovered the initial capital for its user, and is not mining enough revenue to pay for its own electricity cost (fixed at 0.098 USD per kWh, calculated using an ideal AntMiner S5 hashing at 100% uptime per PPS payout), whether because of difficulty increase or BTC price decrease, the PACMiC will continue paying out for ten days as though it were running, even if the machine is turned off. If these conditions persist for ten continuous days, the contract will be considered temporarily suspended. During the suspension period, mining revenues and profit payments will also be temporarily stopped. If after the suspension period, difficulty has dropped or bitcoin price has risen, making mining possible again, the contract will be reinstated and pick up where it left off.

Q:Is the PACMiC really risk-free?

A: Like all forms of bitcoin mining, there is a certain level of risk involved. If network difficulty unforeseeably skyrockets, or if the price of bitcoin drops too much, the Antminer S5 units backing the PACMiC may not be profitable to run and be forced to go offline, in which case contracts would be suspended (possibly indefinitely) and the user may not recover the initial cost of the miner. However, the AntMiner S5 is currently the most power efficient bitcoin miner available on the market, and would be among the last to be forced to power down under unfavorable market circumstances. It is our comprehensive evaluation that the likelihood of PACMiC holders not recovering their initial cost is indeed quite low. We ask that all users please understand the risks inherent to any sort of bitcoin mining, and also to understand that there is no such thing as a risk-free product.

20% VAT

 Oh crap ..i live in indonesia.

if you live in indonesia, it might between 6jt - 9jt idr.
i do the math in first page.

Very big hash power (7.7 Th/s), very big (11 kg) product. Definitely not for home use. 7.7 Th/s for 1 machine is great. I would buy only if I have a warehouse/garage.

 They specify they use the specs of an "ideal S5", not an actual S5.

depends on you VAT country law

Guys, how much you pay duty tax for this S5+?

Someone mentioned having a separate PSU for the controller board and/or at least some separate power connection to the controller board and that it 'must' be powered on AFTER the hash boards.  Do you have any insight into that?

3 of their psu's leaves 1300-1400 watts of overhead.


I would prefer 2x 2000 watt servers  and only have 500-600 watts of overhead.

They recommend 3 of their PSU's - https://www.bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694

I would agree with going with server PSU's on these.  Unless you happen to have them paid off ATX is going to be more expensive.

So what kind of Wattage PSUs should one be running?( assuming they are getting 3x identical PSU) for the S5+

Few things I'd like to comment on that may help or may not help with the general discussion.  I got my first S5 from Amazon, I it's new, it's a 90-day warranty.  I think the 90 day warranty is cool. (They literally said the seller was Bitmain and it comes in standard packaging like from China)  Also Amazon is a huge company, dealing through them gives little ole me a bit of muscle for returns or other things because of defects (at least within the first 30 days).  But I definitely got screwed on price, $569 after taxes.  Most of that being just Amazon markup.  (MY FIRST mistake in bitcoin mining).  Then I got a ATX Corsair 750 bronze also from Amazon. (SECOND mistake)  After hooking the things up I was getting like a whopping 83-85% power efficiency rating.  After actually learning what an 80+ bronze/Silver/Gold/Plat/Titanium rating even means then I realized running two of these S5's as a test run (which was my plan at first before trying to turn this into a mini-business.) I would be having massive expenses in kw/h costs over that gold EVGA 1300W2 which is gold and will run two miners solo.  So it accomplishes my objective.  Luckily Amazon with their return policy allowed me to 'correct' this mistake.  I just ordered the other power supply, and am returning the 80+ Bronze supply.  Then I learn about the difference between a Server PSU and an ATX PSU and it is giving me even more food for thought, so definitely 'read, read, read' as you said.

However on the warranty stuff, they start on a lot on the little card (basically about all the ways they can shred your warranty) they give you about not making modifications etc etc.  However on their support/troubleshooting page they literally give you pages upon pages of disassembling the devices and putting them back together and adding thermal paste etc.  No where on ANY of those pages does it say those actions violate or invalidate the warranty.  I had to use those pages because I had a hash board that literally wasn't firing, and I still have 1 dead chip on the other hash board.  Granted, you're not really 'modifying' their device like with the Inline delay that you mentioned between cords.  But while I agree Email in writing direct from Bitmain Support is always the best option.  I'd think they have to grant a little leeway since they are freely offering up instructions on how to basically disassemble and reassemble their device as official 'Support Troubleshooting'.  I take the phrase 'don't modify our device' on the warranty as in don't change the core structure of any of our components  (moving them around would be fine).  But as you are trying to do, you want the CYA.

I completely agree in the future avoiding re-sellers like the plague, even Amazon.  Just buy bitcoins from exchanges and then purchase your goods for Bitmain.  In the least saves a ton on fees and that middle man margin.

(Page in question I had to use to test hash boards  Btw I got the board fixed, loose connection or something.)

PS:  I did not take the actual hash boards off the heat sinks to check the paste.  That was just a little too scary for me right now when dealing with an alien product I just blew $500+ on.

But if Bitmain is going so far as to push you toward pages with that detailed of work for a retail consumer then you should have to have some minor wiggle room as far as doing things and not invalidating the warranty.

With regard to the comment about the stacking and heat, I also agree with you.  I didn't take any of that into account in my analysis  Same with cost on PSUs.  But I also basically am looking at the S5+ as 'made for' a data center environment.  It just doesn't seem to be home miner friendly.  But you're right.  All the other things out there, Bitmain seems to be the ONLY company selling products that offer a true ROI.

I have no doubt they have a plan that is best for them.  I do suspect they also have some of the best unknown electricity rates.  I suspect the got rid of quite a bit of thier S5's during last batch.  And might have but S5+'s in for temporary hashing.

But I think their electricity is so low they likely could run a S5 easily for most of the PacMic contracts.  Although electricity price they give public on it is nothing special - fixed at 0.098 USD per kWh .

I do see uses for S5+'s.  I just see a lot of unknowns.

Agreed. I think they are always one step ahead of what they offer to the public
