Bitmain Antminer R4

[HagssFIN]

The price at the "testing site" which they accidentally leaked out to public was 1000USD but now with the actual release the price for the Antminer R4 is 1395USD.

I have a few questions...I'm considering getting the R4 and it would be my first home rig. Are all the cables included or what else is needed beside the PSU and R4 itself? Will any standard 110v jack really support it?

make a 110v line into 220v is my advice ...check out youtube it is easy to do with just a 220 plug at one end and the 220 double breaker at the other. It involves no wire pulls
you just tape the neutral with black tape at both ends and use it with the standard black for the 220 breaker....and ground...no neutral reguired.

Anyway youtube videos should clear up such a switch on how to make a new circuit (with 20 amp 12-2 wire) and or mod an old one to 220v.

Others on here can offer other advice on specific miner setup or further links to my stuff above

reason for 220v is more efficient

Thank you so much for taking the time to respond to my post. It really clarified everything and I'm having an electrician over in the morning! I will see if it's possible to do that conversion - Do you really think it's worth it in efficiency for simply 1 miner? If I am unable to make the upgrade from 110v to 220v, how should I proceed (is it ok to run it in your opinion?). I am certainly going to look into a whole house surge protector as well. I was initially going to do grounding on just the outlets upstairs, but I assume that wouldn't even be necessary with a whole-house one? But would 3-to-2 prong adapters really be OK to use with all of this mining equipment?

I'd ask the electrician but truthfully I'd go 220v on one outlet..even if it took snaking one in...I'd not use adapters on this 1 line conversion or addition

i use the below surge protectors they have saved my butt 3x in brown out issues that have only mucked up the SD cards

you need to get a plug from the wall to the unit (from the unit to the psu for miner the cord is included) I use this type of 220v cord

https://www.amazon.com/gp/product/B0093WFT6G/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

use the proper wall plug on the outlet you can get from home depot.

But with 100 amp service and heat issues 220v is less of a strain on the equipment or so I understand it

Yeah, this only makes sense to those folks with 3-4c kwh usd equiv electric costs. They probably also are scratching their heads on this on say
a 9 month roi or so (guessing) from even their perspective. (chime in here you lucky buggers)

Thus ..another pretty 'trophy miner' ....never gonna find another 'asic wife' for the home I guess

(not at frigging 14c kwh summer and 11c kwh winter that is....
my 'geography' for electric costs suck)

If your goal is to have one miner, and one miner only, never expand, keyword NEVER. Then yeah a 110v line is ok so long as the cable behind the wall is thick enough to handle a constant 900-1000 watt draw 24/7. Also, keep in mind that whatever circuit you use for the miner probably should not be shared with anything else to avoid tripping it. Last thing you need is for you or someone to plug a vacuum into the shared circuit and blow a breaker.

If you think that you may want to add another miner later on, go for it, wire up the 220v plug. Just keep in mind, unless you're doing the work yourself, an electrician is gonna charge you a pretty penny to fish electrical cables through walls. Back before i expanded the home mini-farm i was using one of these https://www.amazon.com/gp/product/B000U3BVNC/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1 duplex 240v outlets. More than sufficient for two miners given you've got the right cabling behind it (i used 10 AWG).

My question to you is this, if you're going to go through the trouble of wiring up a 220v plug, why not go with an S9?

Side note, why was this thread moved to mining speculation? Pretty sure talking about the R4 is not speculative when it comes from the bitmain website...

300+ day RoI with $0.1 USD/KwH electricity...   with new price over one year.. mining is on dead..

[GayEddie]

Does bitmain know there was a halving?  Their prices sure did not drop in half I don't think they hardly dropped them at all.

[philipma1957]

300+ day RoI with $0.1 USD/KwH electricity...  with new price over one year.. mining is on dead..

Nope  but bitmaintech need make a simple adjustment .  Let us buy the r4 with paypal.

If I buy my r4 with paypal.  and use my discover card I get 1 year warranty added.

This means I have 90 day + 1 year warranty on the r4.

that is 15 months.  roi should be 10 months.

So  here is the deal bitmaintech  allow us to buy the r4 with our paypal account.

And if you do it right and are able, you can use PayPal credit and get 0% interest for like 6 months or something.  Zero interest is free money, so that might make purchasing these even more attractive to some buyers.

looks like max on warranty extension is 2x up to 1 year.   So   90 day would 2x to 180 day warranty , but as you say  if you have paypal credit you get 6 months with no interest.

And a 180 day warranty on it.  makes it bearable   or at least close to bearable. to get one.

It's the same thing over and over they probably have these mine until a sucker is ready to pay more than they know they will make, don't worry though they will sell. Looks like it is the same old it is better to just buy and hold story and buy sticks as hobby miners for fun.

I guess it is hard to keep the price down on there end....even though I think the price is high on these R4's at $1300 bucks....from looking at their past units..they always seem to sell out
quickly...guess it pays to be the only (sorta almost besides Avalon) mining game unit in town.......I understand it from my newbie days...I got a Jupiter in July 2013 that supposedly
would take a year or more to ROI......(it ROI'd in 3 weeks due to the BTC pump due to dumb luck) ...so heck newbies are overpaying for the first batch...but we have to
'infect' er I mean 'inspire' the new crop of kool aid drinkers to crypto I guess

Unless you can really use the heat produce to warm a room you need to warm anyway with electric heaters. But it needs to have a manageable noise level... I strongly agree that the ROI are harder to reach nowadays.

[Mikestang]

Despite the ROI probability of this machine it is still appealing to home hobby miners like myself who do not mine for ROI, but rather for the enjoyment of tinkering.  I'll wait for the used market to develop before I pick one up, or a 3rd party group by, because I told myself I'd never give bitmain my money directly.  But I am attracted to the noise/heat output of this little box.  Of course Avalon has something on the horizon, so I just may end up with one of those instead...

I used to use my miners in the winter as well but such I live in a climate with variable weather so keeping them on consistently for heat wasn't needed.

I understand. It's clear that depending on the setup in the cold months it's really great to be able to use the heat... as long as the noise doesn't make unlivable. They are great for dehumidifying too, they heat the air which takes more humidity and then open the window when it's dry and cold outside and repeat.

That's exactly my situation. I mine for fun. My S7LN is just about earning the electricity it uses. This would actually put me in profit electricity wise but would never make enough to cover the cost of it. So would have to wait for a group buy or second hand one to appear.

APW5, 1300W-2600W PSU
Power chord is not included with the APW5. It requires a C13 chord with a minimum current of 16A. We advise all users to purchase it separately according to their local wall-socket standard

Does this mean that i cant run 1 machine on a 110v 15amps or 2 machines on a 220v 30amps circuits because the power chord requires 16A minimum??

no.  


lets go slow  and explain  

 1300 watts / 110 volts = 11.81 amps

 2600 watts / 220 volts = 11.81 amps

so a 15 amp cord  x .8 = 12 amps     the 0.8  is  80 percent de rating factor due to your 24/7/365 day use.

so 15 amp cords should be good enough.

give me time to link a good 110-120 volt cord
