at 1275watts is it now ok to use something like a EVGA Gold G2 1300watt?
 Been Eyeballing 1600watts ones but 1300 is liek 150$ cheaper Wink

you'd be pushing it pretty hard.

easy solution is to underclock the S9 slightly, such as to 13TH - which would reduce your PSU load by 100W

Under clock a bit more to 11.5th. The 1300  g2 will work fine..

Then figure your math. You save 150 on the psu. But lose 2000gh to 2500th.

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

At current diff that's about $3 per day before power costs. So probably 100+ days ROI on that difference alone... I'd say if one already has a 1300W PSU they should probably underclock. If buying new - I'd buy a server PSU anyway.

Unless price of BTC doubles in short order after halving ( http://www.bitcoinblockhalf.com/ ) of Block rewards early adopters are screwing themselves paying these initial asking prices for S9.

Curious to see what the S9 will be selling for in August.

No technically everyone who buys this is screwing themselves, even if BTC price doubles.  I think the doubling will happen (well 400>800) but the point is you'd be better off buying 3.4BTC and HODL rather than spend 3.4BTC to make 2.9BTC back in the future!

well the 1300 only has 6 atx connectors so lame.
  What server PSU? I only have 110volt outlets. I'm not paying the power bill so don't really care about those costs.
I assume with a server PSU you have to add the 10 atx connectors. any good place for those if so? the cheapos are made with wire too thin for these amp ratings.

If I recall correctly EVGA G2 1300W has 8 PCI-e, two of which are shared but sufficient gauge to do ~150W or so needed for an underclocked S7/S9. A high-quality aftermarket splitter should be ok for the 9th one and the controller can be powered off Molex. Attempt this ONLY if you know exactly what you're doing otherwise it's a fire hazard.

If you don't care about the power costs I'm guessing you won't care about installing a 240V circuit either so perhaps the server PSU route is not for you Smiley

first of all, eight (four singles and two doubles=8); second, I bought two PCIe split cables (for $4 ea) that increase total numbers of connectors to 10. has been running many B1-5 and 6 like this for 6-8 mo already on EVGA 1300. S7 b1,3,5 has similar 1293 wattage, B2,4,6 even less watts.

It's on, get it while it's hot Smiley

https://enshop.bitmain.com/productDetail.htm?pid=000201606080945140191yC0JO150614

$1985 though... not a good price at all

Edit: 153.52 per TH/s vs $150 per TH/s for Batch 1. And shipped a week later. Ouch.

Fahget about it!

I think you guys missed the power consumption of batch 1 1375 and batch 2 1275.

If you calculate it u will see that B1 and B2 are equivalent.



Efficiency is the same, but price per TH/s is higher on the later shipping batch which is a step backwards.


supply, meet demand.

They can make as little or as great of supply as they choose, there won't be any demand from this guy at that price. I guess there will always be those who are desperate enough to get the latest and greatest, or those who do reviews and want the early exposure. I know I made that mistake with the B1 S7's.

It seems to be nearly a consensus that there is a lot of markup built in to that price, we just need some competition or common sense to reach the market to get the pricing in check with reality.

It is all speculation, but you do have historical average to see what may happen in the future.  In 2010 did you buy Bitcoin at pennies on the dollar?  Buy now, it will appreciate in value. 

Exactly, buy coin and leave the S9's to the suckers.  I never thought I'd hear myself say that, but it's true.

LOL- ya, Batch 3 will be limited too. It will be 10 THS and use only 980 watts at the wall....but cost you $1550. Sad

so buy and hold..

 I did both  I am holding coins .  I am buying s-9's.

I will let you know which does better.

and once again  all buy and hold predictions are wrong if this happens below.


Nov 05 2014   39,603,666,252   10.05%   283,494,086 GH/s   coin price was 368

Oct 29 2015   62,253,982,450   2.25%   445,631,364 GH/s  coin price was 295


so buying an  sp20  on nov 5 2014  mining it for  just under 1 year

vs buying a few coins on nov 5 2014 holding it for just under 1 year

If bitcoin is $1000 by then and diff still below 300 I'd buy a couple Smiley

Until then I'm happy to let others crowdfund the pigopolist.

Wow! with that power consumption for 14th thatll be a good buy, but not now i guess Cheesy

Gona wait after halving and may consider, or even wait till the price drops to less than $1k

Are they using the same receive addresses as before?

It would be interesting to estimate how many S9s have sold so far.

Was I helpful?   BTC: 18wQtEDmhur2xAd3oE8qgrZbpCDeuMsdQW   LTC: LbqLtkZ6wTSpwHHuv1tG4J7tHajGdH5QFB   DOGE: D9R5ySAP2DARpxuNKd7hN7ANmqFiGwB9G6

If that happens you'll have 2.5 coins from this miner and I'll have 3.5 from holding.  We both lose with price drop, but I lose less.

If you can't ROI in BTC there is absolutely no scenario where the miner is better than holding.  You gain less on BTC rise and lose more on BTC drop.

And that's if your gear makes it a year.  Remember, you've got all the risk of mining.

<Edit> The numbers change a bit depending on how you run the math with the difficulty near but less than doubling in a year.  Does it drop first then grow exponentially and slow down, or does it drop significantly and then grow steady, or simply grow steady? (rhetorical questions)  It looks like you could ROI BTC in a year if the difficulty is friendly and you have access to good power rates.  I know you're at $0.05, which is definitely good (for not having access to Chinese hydro-power...)

This would put best case scenario as mining and holding equivalent return.  The only difference then is the risk involved with mining.

I would have a working miner in my case

  diff would be  1.57 x 196 = 307 


coins would be 460

so  the miner would be viable  as an earner  1 year from today

it would be earning .095 btc a diff adjustment at 10 cent power

it would be earning .11 btc a diff adjustment at 9 cent power

it would be earning  .13 btc a diff adjustment at 8 cent power




so if growth drops to 1.9 % for  a year like my example

which is did in my time frame

and if  price drops  20%  which it did in my example.

you would have a miner that does  13000th at 1300 watts  a year from today and it would be a viable money earner .


So it would bitch slap your buy and hold idea.  you are wrong in my example..   if you fail to see that and admit it.  you life will always be that of unhappiness and bitterness because yu fail to see you are wrong some of the time.

I will say many cases that can happen that you would be correct about the s-9.

but not my example above.
