ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

Can you power an antminer s7 off an evga 1300 and a corsair 500 watt psu? I'm thinking the 1300 for the blades and the 500 for the controller. Would this setup work?

Assuming B8 or B9 unless underclocked I don't see running 3 blades off 1300 watt's.  Also I don't think it comes with 9 PCIe cables (could be wrong been a while since I have opened a box to one).

It would be the evga 1600 to run all 3 blades if you want to do it off 1 psu on evga series.  I would look at 220/240 if at all possible and there are some great server PSU's.  They have really taken over S7 market on PSU's being used.

OK, thanks. How about a EVGA 1300 running 2 boards and a CX750 running a board and the controller? Do you think this may work. The reason I ask is because I currently run 7 s3s, a s2 and a s5 on ~4200 watts. (3 evga 1300 and 2 CX750) I want to upgrade to 3 s7s which will put me in about the same wattage but I don't really want to buy too many more PSUs. Think I can make this work?

I think the S2 has a 1000w PSU in there that you could use as well.

Nope. I bought the s2 used. It had an EVGA 1500 watt PSU. I thought that was a bonus until it burned up. (wasn't as great as i thought) I replaced it with a 1300. That's where the 3rd 1300 comes from. I plan on keeping the s5, so I need 1 of the cx750s that I am running. I am hoping I can get away with just buying 2 more of the 750s. I'm not trying to cut corners but at the same time I don't want to spend any more than I have to. I figure with the PSUs I have I should be able to get away with just buying 2 more 750s. I hope.

I am running 3 S'7 on  the EVGA 1300's, but they are Batch2, 4.66 units. But I do have them OC'ed to 600 and getting 4.85 steady with .0001err on all 3. I am running the 3 boards on the 1300's and a CX750 to power the 3 controllers. Works great. Pulling 1215w per miner, again thats without the controller and fan. I have fans hard set at 28% for low RPM and quiet. The 3 feed my HVAC for heat and also works great, the fan on the HVAC runs 24x7 and does create a bit of negative air pressure to help suck the hot air out of the miners.

How do you duct them into the furnace? Dryer vent hoses?

Might be a bit rough with the B8/B9. The DC draw is 1292W~ so it would be running the 1300 to the max. Doable but a bit inefficient electricity wise. There would be no problem whatsoever with something like the 1300 G2 + seasonic. I did 1050 G2 for 2 and 750 G2 for 1+controller/fan and i got an acceptable borderline 1440W AC. I'm guessing with only a 1300G2 you'd have up to 1480W AC.

This is because i am on 120V 15A breakers, so the 80% load limit is 1440W at the wall.

[thedreamer]

EVGA 1300 G2's are perfectly fine with S7's.
I've run Batch 1's, Batch 6's@ 4.5TH with zero issues.
I've also run a few sets of 2x S5's overclocked to 1.25TH each for months with zero issues per EVGA 1300 G2.

You can see in the pics, I just cut a rectangular opening in the side of the intake, right before the blower and filter and placed miners right against the opening. No need for hoses or anything. I used sheet metal shears, cut 3 of the sides and folded inward. In the summer I will pull the sheet metal back and tape with metal duct tape they use on duct work.

Yeah but thats 1220~1300W at the wall. With B8 and B9 S7's, what Bitmain is selling right now, you're looking at 1415~1480W at the wall depending on PSU efficiency. So still fine, but very limit.

The efficiency of those is about 0.3J/GH/s with gold efficiency, versus 0.25J/GH/s of the early S7 batches.

Ahh, forgot that the newer batches' efficiency is crap.

Yes, I'd buy a B2, B3, B6, B7 over the current new crap. Here is what I am getting on the B2 OC'ed to 600 and pulling 1215w

You can run the Batch 8/9 S7 using just 1 EVGA G2 1300w no issues.  I ran 2 S7 powered by the 2 EVGA G2 1300W for a few weeks until I purchased my server PSU combo.  It will work with just 2 connection to each Hash board instead of 3 but if you want all ports connected for warranty purposes, you will have to buy 2 additional dual PCI-E cable since the PSU only comes with 2 of those and the other 4 are single connections.  I purchased extra cables for all my EVGAs.  I think this is easier than powering it by multiple PSU and worrying about the power on and power down sequence.

actually, you need just two additional PCI-E splitters like this (to split two red singles):

http://www.amazon.com/JacobsParts-Express-Power-Splitter-Cable/dp/B00JLU0UQ4 for just 3.95 shipped

just remember to separate (slide off) 2pins from 8 (to make it 6+2)-they ship like this (8=6+2)

Yeah good catch on my typo before I could edit it Biodom

im sure this has already been covered but why am i seeing the s7s now on bitmains website for just 900$?

boy am i glad i didnt order two weeks ago, or a month ago, or 4 months ago ?

anyway I saw something in the thread about the s7+ ? Is this going to be released any-day or something? Any links to rumors etc? Google brought back pratically nothing to mee.

Thanks!

When comparing prices you need to member that time is money and the earlier more expensive S7 have had been hashing at a lower difficulty for longer. Not sure if anyone has done the maths to show who was better off?

The S7+ is just a possible product, nothing announced. S5+, 3 Bay S5, was probably done to use up BM1384 Chips, prior to S7 Release. I suspect an S7+ will only happen if they find themselves with a surplus of BM1385 when the S9 / BM1386 is ready for release?

STRICKLY SPECULATION:

Within the next 2 weeks, Bitmain will be announcing a new miner (~S9).  Reasons:  
 - There has been a great deal of time from the Batch 8/9.  The Engineers have not been sitting idle and resting.  
 - The price of the Batch 9 is now capped at $903.  This could be technical glitch, but the price has not risen since the BTC to USD was $382 and is now $412.  

Get Ready.  Your Thoughts?

I am pretty its a glitch. There system was slow to update when the price crashed as well. It can take a few hours to update to reflect the current price. It is locked in at 2.4 btc.

I would say too soon for S9, still life left in the S7. Yes the Bitfury chip will be competition but it's some Months away from a real Miner. I would think at least another 2 - 3 months of S7? However never a dull moment in this game...
