Oh man I missed the release of this!

 I see everyone still doesn't take into account when you buy something like this u tend to be REPLACING other equipment.
  So to me $2100 is a steal, the equipment I sell I will get back around $1000.
no 220volt so I guess its EVGA 1600watt for $320 another costs to add on.
  And selling off that other equipment drops the electricity used by so much for me. insane. ugh can't believe I missed this!
where are more! lol

Hope these don't fry like usual first batches.

I wished there was a 1600w 120v server PSU instead of having to spend $320 on the EVGA.

I know how you feel.  I'd love to run on IBMs 2800s, but I simply don't have the electrical infrastructure to make it work.  I don't have the luxury of starting from scratch and ROI is tough enough without electrical modifications (and what would I do with a ton of 240V when I'm done mining).

That said, ATX PSUs are far too expensive to be a long term solution also.  What I did was grab a few 900W (on 115v) HP-DPS1200s and hard wired them for load sharing.  That effectively gives you an 1,800W server PSU for about $70.  Add the cost of cables and you're still way ahead when compared to EVGA.

Past 750W I don't think it makes sense to buy ATX.  I wish someone would push out a single, or even double, blade version of the high efficiency chips for home mining.

Check eBay.  Just bought the EVGA SuperNova 1300, new for $149.00 plus shipping.

[Amph]

so no for a small factor for this miner? soemthing like 7T but with 650w or around that?

[QuintLeo]

I wished there was a 1600w 120v server PSU instead of having to spend $320 on the EVGA.

 Run 2 miners on 3 of the 1300 G2 would be less expen$ive.

 As long as you don't mix PS on the same hash board, it should work - I ran 3x S5 (or 2x S5 and my SP20) on 2 1300s (or 2 Seasonic X1250) without issues, just make sure to power things up in the right order.

Could anyone recommend a power cord (preferably Amazon Prime) that would work with the Bitmain APW3-12-1600 PSU's that would work on 208v and/or 220v? 

Thanks.

I will look for one.

so the power supply end is a iec320c13

but what are you plugging it into?  





this wall plug?

notice 14awg  for the sake of safety in both types

[sidehack]

It really does depend on what you're plugging into. There are a dozen different outlets for 240V.

I usually look at Iron Box Electric's eBay store for cords. I know that doesn't help the desire for Amazon Prime but they got a wide selection; about a third of my hosting (on 208V) is running through miscellaneous cords I got from them.

That is it, iec320c13 to USA 3-pin plug NEMA 5-15P.  I presume that 14 AWG allows me to run it on 208/220v whereas the 16 and 18 awg limit me to 120v?

Thanks again.

No, the wire gauge allows you to run the higher current required for a 1600W PSU. You'll be looking at 7-8A, which you'd want minimum 16AWG (and 14AWG is better) to keep it from being a fire hazard.

yes this is the correct answer.

I run some pc's mining eth coin.  as summer power rates in my state are 16.8 cents with about 1.2 more for cooling so only eth coin makes money at 18 cent power cost.

 I run 2 card 400watts   which is under 2 amps at 240 volt power .  I am using an 18awg wire  cool as a cucumber   since it is about 1.7 amps

I run a 4 card 800 watts pc also that has a 16 awg cable  since it is 3.5 amps  and it is also very cool.


I used to run a 2980 ibm  server for 2 avalon 6's   and it had 14awg  because it was pulling  9.6 amps and is was not cool or warm  but somewhere inbetween.

Will these be any good after the halving?

[hawkfish007]

Will these be any good after the halving?

S9 will be the only miner that will be any good after halving if you are paying $.10/kWh or more for electricity.

This is most likely the correct answer.


to further explain it


todays network has :

400ph of older then the s-7

900 ph of s-f or avalon 6

500 ph of newer then the s-7 ie the s-9  

when the ½ ing comes   the older gear then the s-7  will be pretty dead.  

so 200-400 ph of useless gear.
the s-7 will be hurting  so 600-900 ph of okay gear

the s-9  will be king  say 500ph right now.

I would guess 200 to 400 ph will drop off the network very quickly in July

Is this ok for EVGA 1300 PSUs?

I would guess 200 to 400 ph will drop off the network very quickly in July

I keep seeing this claim that 400PH is old gear.  How is this determined?  In an earlier post you pointed to the network size last September and noted it was 400PH (before S7 and Avalon 6).

Do you really think that every miner that was plugged in last September is still plugged in today, or more importantly, will still be plugged in on July 10th?

1. Miners brick, hashboards melt, chips die.  Surely some % of that 400PH has already been replaced by S7s or Avalon 6s because it's dead.
2. Gear becomes unprofitable.  Sure, it generally migrates to lower power areas, but what about heavy units like S2 and S4?  Surely some % of that 400PH has already been replaced by S7s or Avalon 6s to chase profits and it simply couldn't migrate to a better (cheaper power) home.  I would argue that plenty of S3s have even started to hit the garbage rather than migrate.
3. Miners ignore ROI logic every day.  This thread is filled with people ignoring BTC ROI.  Why shouldn't some also ignore fiat ROI?  There are always people who will mine at a loss in the hopes of huge BTC price increases.  Surely some % of that 400PH will stay on the network regardless of profitability.

We can see downward spikes in the network today.  Surely some of that is a result of that 400PH gear coming offline as we speak.  That hash power is still being replaced by S7s pumping into the market.  Even today S7s are replacing older gear and the network flattens out, then grows.

I guess my point is that we don't know how much of that old gear is on the network, let alone what percentage will come off the network.  What I can tell you with 100% confidence that it won't be 400PH, plenty of that was replaced months ago.  I know because I lost a board on an S5.  Right there the older gear has to be 400PH - 0.55TH. 

Will these be any good after the halving?

Depends on what you're looking for.  Will it be the best miner on the market?  Sure.  Will it return your initial BTC investment at $0.1/kwh?  Not even close.

Wow philipma1957 this is the first time I have seen anyone put numbers to the current hashrate.  Just curious where you came up with those?  Was it discussed on another thread?  I'm thinking those numbers are pretty realistic!

 I think you also have to consider the price into the numbers.  As far as paying for power to run the miners, if Bitcoin is $450/coin, $600/coin, or $900/coin also plays a part in how much gear gets taken offline.

I agree, but do you really think the coin will rise when everyone will have to update wallet and address with the soft fork or their btc will become worthless? I'm looking at a crash more than anything... (unless I didn't understand it correctly)

Male Plug: British BS1363 fused with 10A fuse 3P (molded with 60P PVC)
Female Receptacle: IEC60320 C13 (molded with 50P PVC)
Gauge: 1.0mm
Voltage: Up to 250 Volts AC
Amperage: Up to 10 Amps

it is the minimum .  

1.02 mm = 18 awg  and on 240 volt that can handle 1400 watts with out issues ( in theory )

having used 240 volt with 18awg/1mm  some cables fail over time

I look for 16awg/1.15mm   for a 1300 watt psu.  it is safer.


as for network numbers  they are merely an estimate.

400>900>500

why do I stick with the 400 pre s-7 ,

   because I clocked all sales of bitmaintech on their master btc addy
 I also clocked avalon's claim on the  6 sales.

if you ant to say  350 950 500 fine.

if you think it is 450 850 500 fine

if you think it is 0-1300-500 I will agree to disagree .

I know because we have the solar array .

think of the solar array as a bank cd.

you put down 100k and get back 7k a year (no bank pays that any more)

So while I have a limit to the power in the array  my price for power is 0 to 5 cents
the grid buys excess power for 5 cents.
so no gear would earn 5 cents a kwatt thus the 5 cent as a max
the array cost next to 0 to maintain thus the 0 cents.

we have 2 sp 20's and a s-5 they will turn a profit at 5 cents after the ½ing of 9 cents a day

and if you figure the power is 1 cent they turn a profit of 58 cents a day  x 3 = 1.74 a day

so people are certainly running them now and they won't after the ½ ing.

so whether   the old gear is  250ph 350 ph or 400 ph.  tons of it is going away.

if you have free power and toss out your pair of  s-5s   for a really cheap s-7  your hash goes from 2200 to 4600  your power goes from   1200 to 1300 watts.


so the old gear cheap power guys will toss out the s-5 and avalon 4.1 and grab avalon 6 and s-7.

If you look at the numbers for the last halving, the hash rate dropped about 10% but came back to the prehalving level within a couple of months. Given the self tuning design of Bitcoin plus the fact that there have been no code changes that affect its fundamental balance, perhaps we can expect a similar effect this time.

I'm going to go out on a limb here and say that a 400 PH/s drop at the halving is wishful thinking. It will probably be more like 140 PH/s, and short lived (60 days or less).

That said I'm looking at this purely from the historical perspective, trusting that the built in balance factors will provide a similar result this time around. Phil computing the drop based on his estimate of various miner models currently running, which also seems like a reasonable way to approach the problem.

The real answer will likely be between my pessimistic and his optimistic number. But if you're trying to factor in the hash rate decrease for your ROI calculations, it's probably safer to be pessimistic.
