8 Kw/Hr in one room? Possible?

[joshv06]

Hey guys,

I am a total electricity noob. I know a bit, but could use some help.

I bought 12 HashFast Babyjets, that use 350 Watts each. (4.2Kw/hr total)

I wanted to know if it was possible to pull that much electricity out of 2 wall outlets (2 with 2 ports each).

Right now, the breaker trips at ~1400 Watts. (15A breaker)

I have 3 locations I can host these at, but would prefer them to be all in my room.

I know I am going to have to upgrade the breaker (calling electrician tomorrow), but is this possible? Is there a limit?
Would anything have to be done to the wiring?
Would this cause any problems throughout the house?

Thanks!

Your going to be limited to 200A is most residential breaker boxes, with 15A normal breakers plus water heater furnace etc.

Your going to have alot of trouble running that from one location power wise, let alone heat and noise.

Thanks for the reply. But is it possible? Considering I pay an electrician to upgrade the breaker.

By room, do you mean you intend to sleep in there?

Your biggest issue will probably be that the physical lines carrying electricity to the ASICs aren't rated for 25A+ each, which'd probably require a good chunk of change to replace. Especially because you're running them 24/7, anything which may disallow the line from adequately dissipating heat could be dangerous.

You'll probably need extension cords to split the load up among four different lines.

Yes. I managed last winter with 4 watercooled 7970s (1250 watts). Even with those running, room was still cold. My room used to be a garage, gets cold. I will find another location for these in the summer. But for now, yes, my room.

Also this.

I ran special 20a lines per outlet specifically for the 1300+w loads.... It's just not safe unless done properly, and that is very expensive to do residentially. Extension cords carrying that load will also get very very warm... Not a very long term solution.

Gocha. I have 5 wall outlets (plus 1 in the bathroom, in my room), each of course with 2 sockets each.

So if I'm getting this right, I can save on just getting an electrician to upgrade the breaker, then split the power between the lines?

Instead of splitting the load on 2 lines that would have to be upgraded.

First, Watt (W) is a measurment of power and Watts x hours Wh (or kWh) is a measurment of energy.

1 Watt = 1 Joule/second

kW/h is meaningless.

Now that we have that out of the way.

350 W x 12 = 4,200 Watts which is in deed 4.2 kW, the amount of power you need.  If you run this system for one hour you will use 4.2 kWh of energy.  At say $0.12 per kWh this would cost you 4.2 x $0.12, about $0.50 per hour to run.

Assuming 120 Volt outlet x 15 Amps give you about 1800 Watts.

Unil it became totally unprofitable I ran my 1800 Watt mining rig off of one 20 amp breaker and it worked just fine.

4.2 kW / 120 Volts about 35 Amps so two 20 amp breakers should do the trick.

But you might want to break your units into three groups of 4 and run each group of 4 units on a separate 20 amp breaker.

You could even use four 15 amp circuits if you want to just use the outlets you have.  Just use 4 groups of 3 units each.  You have to make sure that each group of units is on a different circuit and different circuit breaker.

3 units x 350 W = 1050 W / 120 V = 8.75 A = small enough to work on a 15 amp circuit

Well - that assumes every outlet is actually on a unique line, which often isn't the case. How many outlets are supported by one line is generally determined by building code, which means it's usually determined by when the house was built. Best (tedious) way to check is to just flip breakers on and off until you figure out exactly which lines support which outlets.

Thanks for the input, guys.

We build the re-molded the house last year. Put new wiring. I'm gonna go in the attic and check which kind it is..

[MoneyMorpheus]

I now see I took too long to answer...

2.5 mm cables are rated at 20a @ 110v thats 2200w @ 220 is 4400w, check the cable diameter to see how much you can load it and change the breaker accordingly. If you have 220 the it will suffice with 1 line, at a bulb and the breaker will jump. You will have to see what else is connected to the lines and plan accordingly...

You can also draw 220 from the breakers if you add another one to hook them up in series, that way you can save in cable supplying a 4400w line instead of 2 2200 and probably the psu will be able to handle both voltages. Just remember regular sockets are rated at 10a, so you will need to put 20a sockets, like the ones the air conditioner uses...

I would put them near the breaker because cable is expensive and miners are noisy though, also if heats get crazy you may suffer a stroke and brain damage:

You just need to look in the breaker box and like Kluge said figure out which breakers go to which outlets.  I don't think you need to go into the attic to do that.

[joshv06]

1 breaker goes to all the outlets in my room. Just checked.

That is normal and expected.

Just have a dedicated line run from your panel to wherever, preferably somewhere where the noise isn't going to be a health issue.

Actually explain what you want to do, emphasize 24/7 and don't cheap out. Electrical fires are terrifying.

[surebet]

So I had another product in mind, did you just buy 70 grand of hardware sight unseen without considering where you'd plug it in?

Jesus fucking christ.

Just have them hosted.

[BurtW]

Here is another thing to think about:

Imagine running a standard hair dryer in your room, full blast, on the highest setting of 1400 Watts.  Leave this hair dryer on all the time 24 hours a day 7 days a week in your room.

Now turn on three of them and run all three of them all the time, in your room...

Pretty toasy eh?

This.... I almost got a dedicated facility for my personal miner then decided to branch into hosting.
