[SOLD OUT] 1.45 BTC Antminer S1 180GH/S Shipps on Feb 13 (Price Protection)

[apap100]

you could always underclock the S1, but who would want to do that

[sushi]

EMS can be an option depends on the country.

hello im sorry i wanna ask a question. im a newbie and interested with this group buy.

in my country customs really shit. they dont allow if a item's price is 100$+

i will pay with btc.

can you send shipping with 55$ price on shipment invoice and as a gift? also ems shipping is avaible?

thanks.

[r4square]

Those who received by UPS,  were you charged a brokerage fee? I might prefer EMS instead as well. Is EMS available for Canada?

[visdude]

Does the specified length of the S1 (300mm) include the fan or just the frame?

[TWO HOOTS]

I'm about to pull the plug on a bunch of these. The only thing holding me back is because the way my apartment is setup I'd have to have sets of three S1's in three different rooms and don't want to have have ethernet cables running all over the place. I see that they have wireless capabilities, but I haven't been able to find out any information about that, except that I may have to buy an antenna. Can anyone chime in and give me a breakdown of using these with wifi?

[anykeywhy]

Happy New Year @sushi!!!

[hausky]

please reserve 1 unit for me, I'm just going to transfer my btc so i will send you the BTC by 1 or 2 days hopefully i have ordered on sushi-review.com.
And i want my Antminer to be overclocked before shipment if possible.

[visdude]

Yeah!  Gung Hei Fat Choy!

Noticed the price of S1 incrementally dropping.   Is Bitmain about to release their next geneation antminer?
Have you recieved the operational specs on it from Bitmain?   What is power consumption and what hash rate will it max out at?
Thanks

[jimmyl]

eyeing 1, can recommend a very suitable psu for this?

Will a normal Desktop PC psu do?

the drop is due to the difficulty rise more then any other reason.  a drop occurs close to a diff increase..

which happened today we went from 2100 mill to 2600 mill   and that means the s-1 is worth less. today then it was a few days ago.

Using any miner over wifi is a subpar solution. IE less income produced than wired internet.  Unless you RFI/EMI shield your place with some EMI Paint and maybe a copper weave which is still only an improvement on wifi.

Bitmain seems to drop prices regularly to keep their hardware selling vs the standard gouging of other companies.

Powering the ANT S1:

Looks like 360Watts for the standard clocks and 480Watts overclocked.  Here is a formula for those who pay for electricity to properly power the ANT for the LOWEST cost.  (Aside from just hosting with sushi


Efficiency numbers are based on http://www.plugloadsolutions.com/80pluspowersupplies.aspx

For an 80 Plus Platinum power supply the best efficiency is around 50% load and must be at least 92% efficient:

Standard clocks: 360W/50%(peak efficiency point)/92%(efficiency at peak) =782W.
For standard clocks on an 80Plus Platinum certified PSU you would want a 750 or 800 Watt power supply.  You can lookup the model of the PSU on plugloadsolutions and find a graph of the efficiency of the particular model to find the best load efficiency.

Overclocked: 480W/50%/92% = 1043W
For Overclocked ANT on an 80Plus Platinum certified PSU you would want a 1050 watt power supply.

RAILS:
If you get a single rail PSU you don't need to worry.
If you get a balanced dual rail PSU make sure the two rails are of equal load and you MAY not need to worry.  Personally I wouldn't risk it as the ANT is two separate blades and may not draw power evenly.
If you have more than two rails on the PSU.  Find the nearest garbage can and throw it away.

I'll gladly run numbers on different models of power supplies or ratings or be told that this info is completely wrong by someone smarter than me.

This is not minimum power requirements this is the cheapest electric cost power formula for those worried about power bills.

EDIT: that last division point for the efficiency is proly wrong

Sushi,
Gimme a price offer for 27 S1 on pm or mail pls.

you could always underclock the S1, but who would want to do that

has anyone underclocked to 150gh and come up with a power number?

 lets  say at 150gh you use 225 watts vs 360 watts at  180gh  and 440 watts at 200gh.

Bigger savings would come from undervolting which probably (?) requires hardware mods. They claim < 1j/gh on the chip at low voltage but no evidence the S1 can do this.

BTW, nice to see you over here Philip. Away from the pre-order madness.

Thats not really true anymore. Most 80+ gold/plat PSUs have only a 1-3% drop off in efficiency between 50% and 80% load, with another 1-2% at 80-90% load.

[iglasses]

If my UPS (APC 1500) is to be believed my ant is only drawing 400w OC'd.  When I first clocked it it pulled 430 but it settled at 403 and the hasrate did not drop off.
