Topic: spondoolies price drop How will bitmain respond? (Read 2846 times)

well depends if you are like me and mine in an attached garage you know your max watts.  

you buy stud psu's with long warranties they outlast your mining gear which is disposable.

I can max 6000 watts 24/7/365 in the winter.

  5 evga 1300 g2's and I am there.  I do not have to buy anymore psu's as they have 10 year warranty.

I have 5 evga 1300, 1 evga 1600 ,1 seasonic 1200. 

keep a spare psu and you never factor in psu cost again. Since you can cover  max watts.

So psu cost is meaningless to a lot of older longer miners such as myself.

Not to say your way is wrong it is different and if it works for you cool.

I don't keep spare psu's just lying around. lol. (ones I already have are plugged in).
And psu's should be factored into costs since they are necessary to run the hardware.

if you need a psu these are not for you. at this stage of mining psu's need to be in hand.

my elec is around 8 cents / kWh.
If each S5 is $310, + power supply $100 + shipping $15, I'd be looking at $425 total cost per unit.

ROI is around 8 months, provided that difficulty and price remains constant.
8 month ROI timeframe is a little too long for me to be comfortable with.

A price drop of $100 per unit (to $210 each) would put me near 5-6 month ROI, which would be a reasonable investment given the risk.

Yeah if I buy the 3 I would keep one and sell 2 on ebay.

So a decent 10 pack would be good for me.  

Better yet a  a 3 pack   in 1 box.  3 across  a long box need 4 foam packs not 6. So it could ship at 3 for 80 or 3 for 75. That is a savings then sell the 3 at 750.  grand total of 3 for 825 vs 3 for 1020

I have packed 3 and 4 s-3s'  in one box save on shipping and packing.  


As an aside I have

5 30 dollar coupon's
1 40 dollar coupon's
2 45 dollar coupon's

The website is not allowing me to mix the s-5 coupons.

so if I order 3 units.

 my options are use 3 of the 30's for 90 off
 use the single 40-------            - for 40 off
 use the 2 45 off ------------------ for 90 off

well I what to use the 2 45's and the one 40 for 130 off  the 3 pieces   .   I can't.

  I hate shit like this.  I have the coupons I want 3 units and the programmer has done a slight fuck up by not allowing a mix of s-5 coupons.

Actually to anyone that has 1x 45 dollar coupon please send it to my bitmaintech account  philipma1957.


So to : bitmaintech  please give me a 45 dollar coupon  my name on you site is philipma1957 same as here.

I would then have 3 s-5 coupons and be able o get the best bang for my buck.
Or tell your web developer to allow any and all  s-5 coupons to be used on the same order.

look at these coupons I should be able to use the 2 45's and the 1 40 for 130 off my 3 unit order.  I can't.  If you send me a 45  it will fix the issue.

even at the new price, it still never ROI for anyone with + $0.1/kWh

Do most ppl here know there is electricity rate and there is effective rate?

Effective rate is what you should look at. It includes delievery charges + electrical rate.

+1, though the 52-pack is really only a small savings per unit (compared with SP-T, where the 3pack is a savings of almost 25%/unit)

a well-priced 10pack of S5 would be an easy purchase

yeah good point > I have been trying to figure out the shipping angle if you buy

shipping to USA New Jersey

     ups----------fedex-----------dhl

1) 47.77------- 46.87----------- 56.28

2)  83.59------ 75.62----------- 99.00

3) 118.54------96.10---------- 141.27

4) 146.46-----120.35----------181.98

Based on the chart  above buying 3 and using fedex to ship is the best deal for me.  3 x 310= 930 + 96.10 = 1026.10

 I have 3 coupons worth   130  so . 1026.10- 130 =   896.10

  I am going to buy this today.

bitmain needs to come out with nano farm bundles like spondoolies.

it just doesn't make sense to have bundles in moq of 52 units.

bitmain dropped to 310 usd

I can not wait to watercooled SP20, which was tested in October. My first SP20 offered to manually download the TEST  software for watercooled SP20 (Three days later, it was taken off from the list)


Bitmain partner Syscooling offers Watecooling Components for Antminer S5.
Components include cover,waterblock and fans.

It is sad I think spondoolies is cutting their profit to the bone..but at 15c kwh here and the current price of $479 and $119 shipping
to the usa for a total of $598.00 usd I can't get that boat to float esp if as their tech specs state 1200 watts on the sp20.

Still watching but...STILL can't pull the trigger

I've got to say for those places in the world that have cheaper elec the addition of paypal purchases is gonna help a lot imho

but they designed these things in the summer when (if I remember right) BTC was 3x what it is now..so they got to be close
to just 'giving their miners' away at this point from a ROI point of view

anyway appreciate spondoolies offering paypal and etc ..but with ave elec in USA at 15c / kwh still hard to justify at 215 usd
btc prices

anwyay continuing to lurk ...someday

You end up subsidising countries with high shipping costs. Either way though, you're still paying for shipping.

I agree, shipping charges are definitely something that wards me away from making a purchase.

I would like to see Bitmain go back to not charging shipping.  The S5 doesn't weigh more than an s1 and I used to get s1's for under $200 shipped.

My setup calls for sp20's over s-5's

but with proper mods the s-5 is okay other then it is really hard to stack it.

I'm all in for SP20.  Made a trial order of 6 units and after some playing around we decided that theses miners are top notch quality build and the options are endless.
Downclocked all 6 units to 1.2 ghash and power around 620-640 at the wall.
Just as important 3 firmware updates in a week with extra features…. WOW.

Please do it.  Sure they can find more quiet fans in China. Like this cheap one: Gembird DC120SF-12AS3. 

See how it works: https://bitcointalksearch.org/topic/m.10095261

70C at one blade and 66 at another. Ambient temperature is 27.5 C in that room (it's very good for my Gouldian finches). So the blades can be even cooler if ambient temp is lower...

I think friedcat will bring out something with decent cooling. They at least learnt their lesson the hard way with the last prisma line. Bitmain don't tend to listen. Just look at that ugly U3 they just released with terrible stats.

Couldn't imagine it would be too difficult for a quiieter case/fan design given as many as they sell and markup value.  Probably good for them to hear our concern for next design.
