IT is good at 1200 watts or 1 unit/.

it is why I got 5 psu's as in house it is a bit too noisy to run two of them on one unit.

yeah  the delta psu did its job  or by by avalon 741

five of these on hand the psu's are great.

but one of the 80 cables was a serious fuckup

been using viabtc.com

i do pplns

and I do some solo ------  about ½ day  the other ½ I point at mmpool.org  then I go back to 6 days of bcc at viabtc.

I am hold some bcc and some btc

I cash  some of each.

I mine some btc.

A move will be made here  with bcc and btc

I am straddling by mining and holding both

my avalon mine BCC so it is alt coin viable.

1 fire blanket is     $10
the ply wood is      $30
the brackets are    $15
the sound material $61
the 2 by 12 by 8    $10

comes to 126 dollars

but  you will use only ½ the sound proof material  

so under 100 for 3 units  .  and about 12 feet of sound material left over.

I purchased 5 psu's from parallel miner   80 cables and I got one  that was cross wired

I checked photos this is the right way to show the issue

I sent this to the two of us I want to check and make sure I did it correctly

good  same wires to same side of plugs



bad cross wired same side of plug different wires

so picks are closed now

and all of us are too high

I have plenty of pdu.s
The one you linked was a good price.
I don't need any at 80 or 100 or worse yet 200

No worries.

let us know what you get.

oh more sound proofing info for you all

A few more blocks and picks close.

He cancelled my sell.

Oh well.

They wanted bcc only.  Not sure I want to pay in bcc

Surely they don't mean his payouts

Coins can shoot up' in price .   So if you mine and hold. Your roi is speed up a lot.

Coins can crash in price . So if you mine and hold . Your roi is slowed down a lot.

Coin can shoot  up in price. So if you are mining and selling your roi is slowed.

Coins can drop in price. So if you were mining and selling your roi is not as slow.

All those variations  are just a small reason. Why prediction is hard.

I never go past a month.
All I try to do is keep miners that earn more then the power cost.

So if a miner makes 1000 a month and the power cost is 200

I am 800 plus. I put 400 to paying for the gear. And keep 400 in the coin.

It is a juggling act.
It becomes easier if you are ahead.
My gear is paid.
So if I
Earn 1000 and power is 200 I have 800 profit.
I would cash 400 and hold 400 in coin.

The cash in my case is profit not for paying off the gear.

look above those you purchased from minerware will work

now get some of these from parallelminer


use slush for a discount   1 will run 2 avalons

http://www.parallelminer.com/product/delta-2400watt-platinum-94-efficiency-power-supply-208v240v/


two of these  each one to its own  30 amp circuit breaker

this pdu  does 24 amps

you can buy one for now or two

these cables

https://www.monoprice.com/product?c_id=102&cp_id=10228&cs_id=1022802&p_id=24206&seq=1&format=2



and for the 2 psu's you have which work at 120 or 240

these cables
will go from the pdu  I picked  to the psu you picked

http://www.ebay.com/itm/3-foot-Power-Cord-Black-NEMA-C20-to-C13-14AWG-/391469492686?


the setup  will have 2 pdus  2 wall plugs each to  a 30 amp breaker in the wall  make sure 10 gauge

each pdu  can do 5200-5500 watts

4 avalon  each pdu  8 avalon total balls to the wall  +1

missed the 120 volt  psu's  


op link them please.

avalon listed these at 176-264 volts

https://canaan.io/product/sorcerer-power-supply-unit/


minerwarez have these at  110-120 to 200-240v  I know these work ate 120 and 240 I have them
https://minerwarez.com/collections/psus/products/1200-watt-psu-with-breakout-boards-and-pci-e-cables

i know these work at 220 to 240
https://minerwarez.com/collections/psus/products/2400-watt-psu-with-breakout-boards-and-pci-e-cables


so what psu's do you have?

sure here is a good one


http://www.parallelminer.com/product/power-supply-kit-for-2-antminer-d3-dash-miners-94-platinum-high-efficiency-200-240v/


use code slush  for 5% off.


combine with these

http://www.ebay.com/itm/4pcs-6P-PCI-Express-PCI-E-graphics-Video-Card-Power-Cable-to-3-port-DC-5-5-2-1-/381710570908?

no  that is really costly and not needed for mining.


did he put in the circuit?
did he use 6 gauge wire?
what does the receptacle look like?

Let's go slow.

You fucked up. ------- slightly

Give me a minute to go to a real pc.

You need to understand this very simply a pdu is basically a power strip.  that safely derates  the circuit breaker 20%

so a 30 amp circuit uses a 24 amp pdu  which allows for   5200 to 5500 watts safely


there are endless quality 30 amp pdus on ebay  for 50 bucks

they will do  about 5200-5500 watts safely  30 x 240 = 7200 x 80% = 5760 watts max   4 avalon 4's at full power  5 at -1 or --2 setting.

if he put in a 50 amp circuit   you need   a 50 amp pdu  and did you see if he used 6 gauge wire to do it?

50 amp pdu's cost big money  if new  over 300.

a 50 amp circuit was a mistake but you did it.

but luckily  here is a 40 amp  pdu  for sale

http://www.ebay.com/itm/HP-417587-D71-PDU-40AMP-High-Voltage-228481-007-376274-001-/152703430194?


it can safely do 40 x 240 = 9600 watts


and since you are 50 amp circuit  50 x 240 = 12000 watts  x 80% =  9600 watts

so that works

now  look at that pdu  and buy it   show the plug on it to the electrician and have him hook it up.

then buy 4 of these

these can do 2400 watts each  2 avalon 741's each

http://www.parallelminer.com/product/power-supply-kit-for-2-antminer-d3-dash-miners-94-platinum-high-efficiency-200-240v/


so that is 4 x 2400 = 9600 watts


the fuckup you did is not too bad.  but I can not see  the plug on the pdu   to tell you what plug to use.

I told you get the 24 amp pdu's  but you did not listen.

If you really wanted more power he could of run a 60 amp sub panel  with  two 30 amp fuses

you then could have had  2 pdus  each doing 24 amps  total of 48 amps or 48 x 240 = 11520 watts max

second best answer or maybe first best answer.

Depends if you game or if you don't game.

Every gamer should mine.

And if you don't game and have no gear on hand  buy a coin and hold.

The perfect reason to mine with a gpu or two.

And why it is never too late to start mining for a gamer.
