House power question?

[mbauman89]

I have 2- 5 gpu mining rigs, 3- 60gh/s BFL Miners, 2- 10 gh/s BFL Miners and about to hook up my antminer s1. The one gpu mining rig is powered by a evga 1300, and the other is powered by a cx750 and a rm750 and the bfl miners have the power bricks. My question is that i have them all in my basement but i have to run extension cords to different outlets so everything isnt on the same circuit cause i was having a problem with it blowing the breaker. I only have 110v power. I was thinking about installing a 220v outlet but i was wondering will a 220v outlet be able to handle more power then a 110? Also will my psu be able to run on the 220 or do i need different psus? The 3 60gh/s bfl power bricks have a 110/220 switch on them but my psu dont have a switch. How many watts can i run on 1 220v outlet(if it possible to figure out)? I know how to install a new breaker and what not but i have no idea what the limits would be. Any information would be greatly appreciated!

Installing a 220 circuit will have double the capacity, so about 3000 watts max (may not want to run that much continuously). But considering your situation I would just put in 2 or 3 110v circuits. They will work with all your power supplies and be useful for stuff in the future.

[mbauman89]

well everything is pretty much 5 feet from my breaker box that why i was thinking about just adding a 220 outlet might be able to add 2 cause i think i have 4 spot left in my breaker box. I guess i could just add 2 or 3 110 volt but i thought you use less electric on 220 then 110?

You can put like 40A on a 220 line, that's 8800 W of power.  You'll have to size the wiring and breaker correctly.  The more power you want the more expensive both are.

[chadwickx16]

All of my PSU's are running on a 208v power circuit.  No issues, if your PSU doesn't have a switch it is most likely auto-switching. You can verify online or on the Power Supply itself. It would say "AC Input 110-240v".  I know that the CX750, RM750, and EVGA 1300 are all auto-switching and capable with 220v circuits.

220v line usually requires 2 "slots" on your breaker box.

[mbauman89]

yeah i have 4 slots available in my box so i could add 2 220 outlet. My feed from the pole is 100amps so would a 40a 220v socket work? Is it true that 220 is more efficient then 110?

[beatljuice]

No the more efficiency thing is buncus.

There is an advantage to 220v over long distances if you were actually running 220v - but what you're really doing with 220v on a household circuit is combining two 110v circuits so you aren't gaining the more efficient transfer of higher voltage.

Yup it should be a little less than 10% more efficient.

Please be careful and consult with an electrician. Just because you have a 100A feed from the pole doesn't mean you have 100 amps continuously available. For example, your main breaker may only be rated for 80 amps continuously.

you do know that your bfl gear is very power hungry?

  1 ant miner s-1 has the exact same hash power as all your bfl gear combined.  Have you considered selling the bfl gear?

and using the money to buy an s-1 miner?

The power savings would be big.
Those power bricks use a lot of power and are not very efficient.


 Oh as for putting in a 220 volt line  it would be okay as long as it is cheap.

If your electrical service can do 220 (you need the proper wires coming in)  and the cost is under 200usd go for it.

And with a 100 amp breaker your home maxes out at 9000-9600 watts total for 24/7/365 use.

120 volts x 100 amps = 12000 watts peak    safety factor is 75 or 80%  of that or 9000-9600 watts

[mbauman89]

well i dont pay for power thats why i still use my bfl gear...

[PizzaTraveler]

Wow i was never good at physics and electricity...

[fractalbc]

Are you looking for a short and sweet answer?

Oik.  Install a l6-30 outlet and plug a 30 amp 220v PDU into it.  Plug anything that will run off 220 v into that pdu and you will be happy.

Don't run extension cords.  I am sure you already know they are fire hazards.

Or were you looking for a long, detailed explanation?

You could install 4 220 circuits or 8 120 circuits.  You may be able to convert some of your existing circuits to doubles and get even more.

220 has less wire loss which is of little value here.

220 has a slightly better power curve in PC power supplies.  A couple of percent is a couple of percent.

As long as the sum of what you are running now is the same is what you plan on running once you get rid of the fire hazards ... do it.

Oh, and while there technically IS a 220v 40A socket, I haven't seen one and it is not common in computer equipment.  220v20a and 220v30a are common.

Thanks guys. I installed 2 220v 20a sockets. Just waiting for the building inspector to come by to check my work before i can hook up the wires but i got everything run and its all to code. Thanks for the help! Anyone know a good place to get like 5 of the psu power cords for 220?

I ordered mine from Digikey.

newark ,jameco , sometimes amazon even ebay used surplus  ones.
