And thank you Bitmain!  Ordered 10-16, Batch 3, shipping today via UPS, I should have it on Thursday.  Only 1 unit, but I've been hurting after selling some S5's to pay for it.

Although it's good to see that bitmain are finally getting their shipping act together, it's very frustrating/annoying that they are shipping B3 orders while many B2 orders remain neglected, mine included.

@ BitmainWarranty/BITMAIN_YHQIN:

What is the reasoning behind this?

What compensation will you be providing to delayed B2 customers?

Why is B3 taking president over B2?

[fullzero]

Is there anyone who ordered within last week who already received a shipping number or are they still shipping orders from early October?

My order from 2015-10-20 is not shipped
     order from 2015-10-08  arrived yesterday.

  order from 2015-09-29 Batch 2 should arrive tomorrow
  order from 2015-09-29 Batch 3 should arrive today

  I didn't receive a shipment notification email for either.

So just to verify, wil I be ok with 3 Corsair HX850's to power a single S7?  One PSU per blade with the third also powering the board.  I have these PSU's sitting around after selling off the 3 S5's they were powering.

You would be okay with 2 of those.  Don't need 3.  The only way you would need 3 is if the HX850 did not have a sufficient number of PCI-e connections.  I'm not familiar with how many PCI-e connections the HX850 has.  I have a lot of AX860's laying around.  They have 8 PCI-e Connections on the back of the PSU.

Make sure you use all 3 PCI-e cords on each blade because the gauge wire for the PCI-e cords provided with the HX850 PSU's are small compared to others that are custom made.  If you had custom made PCI-e cords that are 16 gauge like mine, you would be fine with 2 PCI-e cords for each blade.  That's my opinion.

I used 2 Corsair AX860 Platinum PSU's to power one S7.  It works fine.  I did have to do a soft reboot after initial power up to get it to hash at 4.8 TH/s with low HW errors.

HX850 has 6 so plenty. You can use the data table in my PSU comparison.

Well shoot, I need to look at my PSU's again.  I could've sworn they only had 4.  But I think powering 2 boards with one HX850 using 6 cords would put a lot of strain on that.  I guess I'll keep it at 3 PSU's for my single S7...if the rumors are true about the S7-lite, then I'll re-evaluate my power.

I looked at the pic on the corsair website, four connectors.
You can only do one HX850 per board safely. Can't have 2 psu's on one board.
hx850 3 cables to first board
hx850 3 cables to second
hx850 3 cables to third, fourth cable to controller.
I have an hx750 here, that would work for one board also. 4 connectors.

Actually I think Dogie is right on this one.  There's 4 modular pci-e connectors, but there's also 2 more in the wire bundle that I didn't pay attention to.  But I'll still parse them out to one per board for now.

I am thinking the new miners are doing better than the batch 1 were and they are not getting enough 4.6 miners to fill the B2 orders. You may very well end up with a miner that does 4.8+ which will still be a bargain for the price if the wait is not to much longer.

Glad I went with all batch 2's on the second wave. Seems to have paid off.
I just figured if I was getting nothing so far that B2 would be easier/faster to get because nobody would want them.

Thanks for clarifying.  Appreciate the link for the PSU comparison as well.  Looks like you did a lot of research there.

[jaipagare]

So is that a right choice to buy http://www.frys.com/product/7590536?site=sr:SEARCH:MAIN_RSLT_PG for S7?

I haven't seen S7 personally with my naked eyes, however I am sure 10 x 6 pin PCI-e connections has to do with connectors.

It appears to have ten (10) 6 pin connectors for PCI-e ports.  It also "says" it is 12 + Volts.  As long as it's 12 and not too much less, you will not have to be concerned about hash rate or HW errors.

Thank You dmwardjr,

You made my day. I will wait for my S7 to arrive. If this PSU + S7 works, I will add more hardware in future.

Now, I need to find the way, how much will be daily power consumption.. :-( I have no idea

Well, after I am been thinking whole night about PSU to fire up S7, I have decided to call up and electrician and get a 240V dedicated circuit installed at my home for my S7 Batch 3 and APW3-12-1600-B2 PSU. Any suggestions?

You will be happy you went this route.  If you are getting a 30 amp circuit, you can have 5 x S7's on that one circuit.  I still like the IBM 2880W PSU's with J4bberwock breakout boards and 3 feet PCI-e cords made by J4bberwock for the breakout boards.  The IBM 2880W PSU's can be purchased used for $60 to $75 quite easily.  The breakout boards can be had for $55 to $65.  The 3 feet cords can be had for $3.25 each + shipping.  So, with one PSU, you can quite easily power 2.5 x S7's versus 1 x S7 with the 1600 watt PSU.

If you are curious about the size of this PSU, here is a link to see my hand on the PSU as a reference for size:  https://i.imgur.com/n6peQ8q.jpg

Another photo with my hand for thickness of the PSU and another with the PSU connected to two S7's with the 3 feet cords (16 AWG) purchased from J4bberwock:  http://imgur.com/a/kRUGv

A 30A 240V circuit takes 2 lines/poles of 120V 30A connections.  This would mean its using 60A of 120V.  60A at 120V would also allow for 5 x S7's.

Why pay loads of cash to change existing electrical layout if you can avoid it?  ROI is already hard enough to achieve no?

If you have a 200 AMP Main Service Panel, you are limited to 200 Amps REGARDLESS of whether it's 120 Volt or 240 Volt.  A 30 Amp 240 Volt circuit does not take away 60 Amps of 120 Volt.  A 30 Amp 240 Volt circuit has taken 30 Amps of 120 Volts [When measured in amps].  The main service panel is limited in "AMPS" not volts!  Yes, it's limited in volts in the sense that your main service panel in you home is rated for 120V/240V.  Other panels, especially for industrial use, can be rated at much higher voltages.

So, again, your main service panel is limited in amps NOT volts.  A 30A/240V circuit does not mean 60 amps worth of 120 Volt circuits have been kept from installing in the main service panel.  I will say this:  60 amps worth of 120 Volts has the same power (watts) as 30 Amps of 240 Volts.  You could have a 30 amp/120 Volt circuit.  However, it would not have as many WATTS (POWER) as a 30 amp/240 Volt circuit.  The main service panel is not limited with a measurement in watts.  It is limited with a measurement in AMPS.  Your amount of watts (power) used in the main service panel will be determined by what voltage or voltages used in the circuits wired to the main service panel.

Thanks,

So what should I tell to the electrician that would come in for survey and to give out estimate first? Well, I am planning to buy another 4 X S7 in future in total 5 X S7.

I want a 5 X 220v 30 amps circuit? What about the outlet where I will be actually plugging in?

Sorry count me as a dump when it comes to power and electrician work.

IBM PSU, is this the one you are talking about http://www.amazon.com/Genuine-IBM-Bladecenter-Computer-39Y7409/dp/B00TMPPFVS


This guy is selling. https://bitcointalk.org/index.php?topic=1206049.0  How many should I buy if I wish to have 5 x S7?


This is really interesting. https://bitcointalk.org/index.php?topic=966135.0     I like the The "Pimp Daddy" Package - $650

So you mean, I shouldn't change existing electric layout? If no, then what are my options? Contact a Datacenter and request Quarter Rack? What should I ask them in terms of POwer? 1 X 30 Amps 240V Circuit? Can I power on 5 X S7 with 5 IBM PSU's?

You  got a good answer already:

You need to know how many amps you have in your main (this is the term for main breaker, some have sub panals where more then 1 breaker but the house should all go through the main).   You are limited to this amount of amps.   It would take a big job to go above what main is.

From what you are saying I highly suggest you get a electrician to come help.  As I hate to send you to a electrical box.

[dmwardjr]

Say we had a 200 AMP Main Service Panel and every circuit was 240V circuits by using 2 pole breakers...  If every circuit was used at it's max [Not recommended if circuits are inside walls and/or conduit], you could have 10 x 20 amp / 240 Volt circuits for a total of 48,000 watts of power.

If we used 10 x 20 amp / 120 Volt circuits in a 200 amp Main Service Panel and maxed out each circuit to its full 20 amps each [Not recommended if circuits are inside walls and/or conduit], you would only have 24,000 watts available in power.

So, both Main Service Panels were rated for 200 Amps maximum.  However, we can utilize the power much better with 240 Volts instead of 120 Volts.  Does this make sense now?

notlist3d, is right...

It sounds like you need an electrician.  Trust me on what I'm saying about available watts regarding 240 Volt verses 120 Volt.  Your Main Service Panel is rated in Amps and Volts.  It's limited for 120V/240V [Either can be used] and it is more than likely limited to 200 amps REGARDLESS of what voltage (120V or 240V) for your circuits in the home.

It's my understanding that you have a 200 AMP Main, it's providing 2 lines/poles of 120V each with 200 AMP capacity service.  It is the combination of the poles that gives you 240V service.

Well, I guess my farm is defying all logic then.
I'm certainly pulling in over 200A total - all using 120V.

[hawkfish007]

I came across some issues with my early B1 S7. I have received it on Sep 24 but didn't fire it up until yesterday. I found that 2 of the 3 boards don't work, so sent an email to info@bitmaintech.com and with their permission I took out the hashboards. Noticed that heatsinks were crooked on the 2 non-working boards and some heatsinks on the other side came off as I was pulling them. Working board's heatsink are perfectly aligned. I re-inserted the working hashboard to run it individually and left the other 2 aside. Now I don't see the second fan on miner status page even though the fan is spinning, I tried changing fan pin location without any success. The miner is running at a higher temperature 64C than my B3 (52C). Is it because I don't have the other boards the fan is not detected? Or, did I screw it up when trying to pull the boards? I noticed that the early B1 boards are somewhat shorter than the later batches (see bottom pic, 1st one is misaligned heatsinks, 2nd one B3 S7 ). It didn't rattle to indicate something is loose before I turned it on, just the 2 boards were loose when I was attaching the PCIe connectors.

[jaipagare]

Thanks a lot guys. This does makes little sense to me. However onsite electrician will help me more with current in house board situation.

I am also considering Data center options as well. Quarter Rack with 30Amps 240V. I don't know.
