10.5 min avg blocks since new diff so might not go up much next round except even at that ridiculous price batch 1 s4 sold out in 12 hours
Batch 1 wasn't that large to begin with, this is from their post in S4 thread:
S4'B1 is limited in quantity, as it is the first mass production after the development stage.
understood still dont see how anyone would buy that 3.4 btc for .01 w gh/s improvement over s3+ .069 vs .070 when 2 s3+ is 1.16 and prob cheaper you can get 4 for over 1 btc cheaper and have same hash rate and I know it has an integrated psu so they wont have to buy 2 140 dollar psu's but they have to find a 16 amp power cord that fits hmmmmm... gonna be tuff 15 amp is what 12 gauge and thats already thicker then standard computer power cord bet it costs a bit and as standard outlets in the us are 15 amp rated I'm sure warranties will be void
Agree, I wonder if they noticed that server psu and those 4 large fans? It is going to be very loud.
S4 was obviously geared for their hosting option or a data center not the home. Either way you will never see ROI with it but sheep will be sheep.
yup i was looking online and it appears only 250 volt solutions for above 15 amp power cords
Wouldn't surprise me if the S5 when it comes out is a 220v only, just hope they don't drop the S3 line.
Don't let this come across as "attacking" anyone:
You fail to realize the S4 COMES WITH A POWER SUPPLY BUILT IN. YOU DO NOT HAVE TO BUY A PSU TO POWER THE THING. We have to buy PSU's to power the 3 or 4 Antminer S3's to get about the same hashing power. I prefer the S3+ at this point in time. However, the S4 will probably have a greater resale value down the road if you choose to get out of mining at some point in time.
So, you save money not having to buy PSU. Their PSU is GOLD rated and not PLATINUM rated like my Corsair AX860's powering my S3's.
Also, someone made a good point about the "watts consumed at the wall." Approximately 1400 watts OR 1380 watts to be exact when you multiply the .69 watts x 2,000 GH/s.
TRY putting two of these on a 20 AMP circuit; EVEN WHEN YOU REPLACE THE STANDARD 15 AMP RECEPTACLE (OUTLET) WITH A 20 AMP OUTLET. You would only be able to put ONE of these bad boys on that ONE 20 AMP OUTLET. 20 AMPS will drive 2400 WATTS.
Do the math: 1400 watts x 2 Bitmain Antminer S4's is 2800 WATTS. The 12/2 wire will get too hot. IF you have 14/2, YOUR HOUSE WILL BURN DOWN if the breaker doesn't trip!
SOLUTION:
RUN 10/3 wire [Rated at 30 AMPS] to a 30 AMP OUTLET [NEMA L-14-30-R (circular/4 prong)]. IT MUST BE NEMA L-14-30-R/CIRCULAR. OTHERWISE, IT WILL NOT ALLOW THE NEXT THING I MENTION TO PLUG INTO IT.

This extension cord splits INTO TWO 20 AMP PLUGS to plug in two Bitmain Antminer S4's. It's only 3 feet but it gets the job done. You can add more length with additional cords if needed.

http://www.homedepot.com/s/double%2520pole%252030%2520amp%2520breaker?NCNI-5Problem solved; IF YOU HAVE THE S4's in mind. Now you have 30 AMP circuit [3600 watts] for the 2800 watts required for two S4's
