Damn I paid 13 BTC for 2x S7 and now people is buying them at 4 BTC/piece
This is insane, and diff will sky rocket because of price going up.
This was my worst investment

I am thinking of solo mining with them for a while and try my luck hitting a block ...

Right now this is probably the absolute BEST deal on any miner.

Check the classifieds sections or eBay. Everybody is selling their old, used, and inefficient equipment for much much more.

I am surprised that they weren't greedy and increased the price by 50% on these.

I received my S7 B3's today.... got them online... AND... I found a block. Too bad I was not solo mining otherwise I'd be buying a few more S7's

Wow 3.8BTC for the next batch now. Crazy.

Those who paid 8 BTC or heck even my S7 I paid 5.8BTC for that shoud arrive tomorrow costs too much!

How high is BTC gonna go on this run? Some people may get some sweet deals on S7s but its going to screw the early guys that's for sure!

Is it true that the main problem in mining is efficiency and electricity costs that eat up to 60% of the profit(depending on the prices in your region)?

Well aside from the cost of the equipment, which depending what you are looking at is nothing to slouch at, electricity would be your only other real expenditure (assuming you own the building that houses your gear and stuff). Efficiency of the miner and electricity cost are directly related, so really it's only 1 issue. But yes, I think electricity cost is the "main problem" with mining today and it ultimately will decide how much hash power you can throw down. More efficient gears means more hashes for the same electricity use.

I just wish someone would produce an efficient miners that doesn't sound like a jet turbine and cost less than $400, and uses less than 600W - something like an S3 but with new chips. My S3 is no louder than my desktop computer, but at 0.5TH it is easily outpaced by any of the new gear that is being released like the S7.

Hey, guys,
I stopped mining bitcoins long time ago when everybody switched from videocards to fpgas. So I was out of the loop for a long time. Recently I decided to dig back in and after days of reading forums and analytics I have one question left to make sure that I understand the situation before buying an asic:

Is it true that the main problem in mining is efficiency and electricity costs that eat up to 60% of the profit(depending on the prices in your region)?

You will need to do ROI math. There is no onesize fit's all on amount electricity eats up. Some it can be at a loss even.

What is your electricity price? And do you have a import/vat tax? That will allow us to give you a general idea.

Anybody using 3 PSU's to power one of these?

I use 3 corsair rm1000 to power 2
I would use 3 750's
Don't go cheap.

Well I have a number of corsair 750's, I also have an EVGA 1200 so I could use that plus one of the corsairs or 3 corsairs. The only thing is that I am pretty sure I have enough 750's sitting on the shelf and the EVGA is being used to power 2 S5's. So I can go with three 750's without shuffling anything so I was just curious if anyone else is already doing that and wondering how well it was working out.

I took the plunge and ordered a Batch 5 for 4.222BTC. I may get another if the price of BTC goes up some more and the rest of my transactions confirm. I sent a number of transactions probably 10 or more hours ago now and a little less than half of them haven't ever been picked up. I lucked out that the BTC I sent to bitmain for the miner did get picked up in the very next block. The unconfirmed transaction queue on the network hit 12k earlier today. Sitting around 6k now.

The three 750's should be great. Hash boards use 400 watts and you don't want to run more than 80% of the capacity of the psu continuously.
Just make sure that use only cables from one psu per board. A daisy chain from one cable can power the controller.
Kick the two hash board only psu's on first then the one hash board with controller. Or all at the same time if you have a switchable pdu.
If you don't go cheap and you use less than 80% you should be golden.

i am not sure why you cannot use more than 80%, especially for gold or plat PSU. In fact, in SP30 they used 105-110% of PSU nominal wattage.
80% is for wall circuit where you are not supposed to use more than 80% of 15A, but I could be mistaken.

less than 4BTC/S7 now, sure glad i resisted the urge to buy any mining hardware in the last few months.

when the price is low, accumulate coins. when it is high, accumulate hashrate

The IBM 2880W will power 2x S7's and an S5 no problem, or 2 S7's and another 1 or 2 hashboards from an S7 (since you can't actually split them in half).

2x S7's on a 2880W PSU loads it at 78%, barely even cracking a sweat.

I'm using 3 power supplies per 2 - S7's

Till the IBM 2880W power supplies arrive, I'm using 1 - DPS-1200FB (1200W) power supply per 2 hash boards, there is yet another DPS-1200FB that is dedicated for powering the logic boards. That way I can power on all the hash boards, then switch on the logic as Bitmain recommends.

boring without pix ? let's see some s7's in action. reading can be boring sometimes, pix tells a thousand words.

couple of pages up there were some miners using only 2 pcie instead of 3 per hash board ?

tia for sharing

If you do this and get caught you lose you warranty. Really on such a high priced item it's not worth risking it.

After 90 day's do what you want. But for the first 90 day's I highly suggest not breaking warranty.

My order was UPS. Been at UPS in Lousville since Saturday. If we order more than $2,500, do you think Bitmain would ship them all single? or should we make 10 orders for 10 different address?

This will be 1 week delay.

You will probably have to place single orders for each miner, this way you would pay more for shipping but your shipment won't be flagged or delayed.

It's not UPS, FedEx, or DHL that is doing this, it's US Customs.. Your mileage will vary no matter the carrier and don't think systematically sending multiple packages under the limit at the same, or in a short time period escapes notice of Customs as they will wonder if one is trying to skirt the law.. At the end of the day the goods do not have a tariff so it's not a big deal for the US, some big and some small packages get flagged, it all depends on timing and luck...
