Topic: ANTMINER S3+ -B8 VS ANTMINER S3+ -B9 (Read 2085 times)

Nice work
   I have done some of the same calculations and have come to similar numbers.
     After much thought I ordered the s1 upgrade kits.
It keeps getting harder to ROI. So hardware cost and power become much more important.

again---- nice work.
 

Actually, AM Tubes are cheaper per Gh/s than S3s and are always available for immediate delivery. The S3s are more efficient though. I posted the following earlier in the Spondoolies thread to show how crap the SP20s are:

Let's assume a static network hash rate of 300 Ph/s, power costs of 0.1 USD/kWh and an exchange price of 500 USD/BTC.

SP20 costs 2.64 USD/day,
SP35 costs 8.4 USD/day,
S3+ B9 costs 0.86 USD/day, and
AM Tube costs 2.16 USD/day.

SP20 at 1700 Gh/s would mine 0.0204 BTC/day or 10.2 USD/day,
SP35 at 6000 Gh/s would mine 0.072 BTC/day or 36 USD/day,
S3+ B9 at 453 Gh/s would mine 0.005436 BTC/day or 2.72 USD/day, and
AM Tube at 800 Gh/s would mine 0.0096 BTC/day or 4.8 USD/day.

SP20 would make 7.56 USD/day profit,
SP35 would make 27.6 USD/day profit,
S3+ B9 would make 1.858 USD/day profit, and
AM Tube would make 2.64 USD/day profit.

SP20 costs 1,500 USD inc. PSU + shipping, it would take 199 days to break even,
SP35 costs 4,035 USD inc. PSU + shipping, it would take 147 days to break even,
S3+ B9 costs 320 USD inc. PSU + shipping, it would take 173 days to break even, and
AM Tube costs 500 USD inc. PSU + shipping, it would take 190 days to break even.

With the SP35s not being shipped till November and the SP20s being shit value, it basically comes down to how long you have to wait for the S3s. If the wait is too long, you'd be better off getting an AM Tube.

750 or higher should do it per ant s3 i gonna use one HX 850s 80 PLUS GOLD Certified per ant S3 I have two HX 850 in route to me .




I have one RM i use right now but i got a really nice deal on the 850 S so why not .

To be on the safe side , just buy a good pc psu like cosair rm 750 , rm 850 or rm 1000w.  Quick and easy . Just plug in the pcie slot and mine.

You can use it, you need to figure out pins of your psu or search for breaker board for it.
I like supermicro servers, so I have spare parts from them and use PSU from it, but it was DIY projects to figure out pins and make it work for S1. And they are loud. I made little quieter switching to bigger fans.

Sorry J4bberwock ... with "server PSU's" do you mean a realy PSU from servers ? ...sorry but I'm start this days :-)

I ask you because i have some IBM eServers 346 that I don't use and maybe
I can use this PSU ... If I remember I have 2 X PSU for every server.

Thanks a lot again

Why do you say that?  Bitmain is by far the best for small and large setups.  Dollar wise and W/Gh wise Bitmain destroys everyone else.  What have you been patient for?  B8 shipped 10 days early.  Why are you complaining about the only worth while manufacturer???

I was one of the last to order from B8 and it shipped last night.  B9 is set to ship the 18th and I have no doubt it will be on time.  BITMAIN WINS!

I use a Corsair RM 1000, solid rock PSU. Not cheap but silent.

best bang for bucks are always server PSU's with breakout boards.
If you prefer a standard ATX, search google for PSU review.
There is also a PSU review from Dogie, if I'm not mistaken.

I just buy 2 pcs of B9 today, and I hope they
send it as soon is possible.

In the mean time can I ask something please ... can I use only 1 PSU
in order to overclock (just to arive at 500 + 500 ghs) ?

If yes... witch one is a good for this please ?
Thanks a lot
Denis

Nah, they will still ship B8 first, and I dont think its worth buying B9.

  nice will shipping on Sept. 18 and this B9+ is shipping faster than anyother batch.

Looks like Bitmaintech sold, and from the looks of it not going to be good for small miners. No price break and even though product is overpriced I have been asked to be patient. I for one have made my LAST purchase from china. Can not wait till these mega farms kill each other off.

B9 is probably last Bach of Antminer S3+
I just purchased a 20 pc S3+ B9
No discounts are  offered, even though I've bought from them miners for more than 70BTC

the shipping date.
The hardware is exactly the same

Hi there all,
somebody know if is there any difference between ANTMINER S3+ -B8 and ANTMINER S3+ -B9 please ?
Thanka in advance
Denis
