A PDU will allow you to plug multiple rigs into an outlet.  If you have an L6-30 type outlet, look at the APC AP9571.  These can be had for a great price on eBay.  I ordered 2 of them from eBay a couple weeks ago.

Using ATX PSU, do I need to upgrade the standard 120v style power cable it comes with if I'm using it on a PDU

what's the ideal breaker size / rigs to run on it / best tool to determine exact power draw?

Electric has been a frustrating component of all this 

[Billz007]

You'll need C13 to C14 cables.  I have the 14AWG (gauge) ones.  Business rackmount servers come with these as well as the standard cables.  My dad's business had a bunch of extra ones.

I was going through the same troubles as you trying to figure out the proper electrical setup.

This link really helped me figure out what I needed.

I'm going to have two 30-amp breakers run to two 30-amp L6-30 outlets.  As far as tools to measure usage, I'm not sure.  But the amps a rig takes at 120v is cut in half when put on 240v.  I think I'll just use a killawatt to measure a rigs amp draw at 120v and then plug the rig into the 240v.  That's the only solution I have right now to estimate amp draw on 240v.

[stoon]

Be cautious but my kill-a-watt tools worked when i used them for 240v as well as 120v. Most of them are made the same just a different plug for different parts of the world.

grab some metered PDU's, nuff said

[gwestcot]

A PDU can be used also to step down in voltage. If you are smart, IMHO, you would setup a 480V 3 phase service with your electricity provider. In my local are you can set up as much as 3000 amps at 480V 3 phase and it is not even expensive if the location has a power pole within 80 feet of the building. Then if you want to use traditional air conditioning then you can get yourself a 30 ton liebert CRAC unit and condenser that will run on 480V. For your mining rigs I would then use 225 kva 480V (input) to 208V (output). Now you have a voltage that your standard PSU can handle. Most PSU can handle between 100V-240V. Does this make sense? Of course this is for a massive build out but the principles are still the same regardless of the scope of the project.

Alright so I've gone to 240v w/ metered PDU l6-20p wall plugs on 30 amps double pole

I need help with the fans, the shed will butt against a wall / hill so I'm thinking attic fans are the best choice here, mount them on the backside slope of the shed?

Thoughts on solar.. .  could it keep up with my usage?

[VoskCoin]

used pdus on ebay  will save you $$$


this will do

http://www.ebay.com/itm/216858-001-Compaq-50-60Hz-24A-4-port-PDU-Power-Distribution-Unit-30-56205-S5-/390708088945?

2 of these

http://www.ebay.com/itm/228480-002-HP-Compaq-High-Voltage-Power-Distribution-252638-001-100-240V-PDU-bar-/131836831127?

this will do   12 amps

so the above would do 24 amps  at 240 volts     which is around 40 gpus


if you do shed  no intake fans

2 exhaust fans high




I would argue in a 12 by 12 shed

using   this to feed in the air

http://www.homedepot.com/p/5-in-Fresh-Air-Vent-FAV5/100119472

cut low holes on one side of the shed.    say  6  and use the vents above.  inside the shed do  a bend up to cut down dust

http://www.homedepot.com/p/Speedi-Products-5-in-B-Vent-90-Degree-Round-Adjustable-Elbow-BV-A90-05/203530661


then use these gable fans and shutters

http://www.homedepot.com/p/Master-Flow-20-in-Aluminum-Gable-Mount-Automatic-Shutter-SGM20/100092056


we have them in the array  



https://bitcointalk.org/index.php?topic=1369207.msg18962287#msg18962287





low intake vents >>>>     shed + gear  >>>>>    high exhaust fans
                                              ^
                                              ^
                                        entrance


if the intake vents  can face north  they would get the least sun.

if you silver bubble wrap the ceiling of the shed less heat from the sun

http://www.homedepot.com/s/bubble+insulation?NCNI-5


note I used it in the solar array

I'm thinking intake vents left front right, rear is backed to a wall / hill then roof mounted exhaust fans? I could wall mount fans on the top back portion if possible but itll blow into a hill and get some bounce back . .

Who's extended their coax cable / do I need an outdoor rated fitting or will any extension type due. The wire is exposed

We ran exterior grade ethernet from the house to our barn to take care of our internet out there. For coaxial, are you thinking of putting in a splitter from your service provider's coaxial line outside of the house to run to an outbuilding?

I actually just need to move it due to the awkward layout of the cord / gravel base -- now i'm thinking to just run the modem there and run a ethernet into the house to a switch / wifi extender . . awkward setup I guess lol


Also need to figure out this attic fan dilemma if anyone has any input!

You could certainly install some roof vents, this is a 1600 cfm example, but you can get more powerful ones if you need it. Just make sure you know what you're doing before cutting a hole in your roof, or get a contractor to do the job.

Do you have experience with these? I'm thinking of putting 2 in to begin on switches, and then one as many as I need to you know?

[Tidsdilatation]

Cool project man! Good luck!!

Well, back when I was younger and in good health I worked a number of years as a general contractor, so I have installed a number of roof vents. I have not installed any for mining related ventilation. For general ventilation in places like a residential bathroom the rule of thumb is 1 cfm per square foot, but you would want more then that for a mining room. There is a handy little calculator for optimal CFM ventilation in a greenhouse. Since a greenhouse gets pretty darned hot , I think that would at least point you in the right direction as far as ventilation needs goes.

That's a really helpful link thanks for posting that . .  based off that and everything else I'm thinking 2 and I should be good to go? Going to install 3 and see how it goes? I'm hoping I can run simply one while my farm is small https://www.lowes.com/pd/Air-Vent-1-500-CFM-Black-Galvanized-Steel-Electric-Power-Roof-Vent/3126703

This seems to have good reviews, fit the idea in mind / sufficient CFM -- thoughts? about to pull the trigger and get this stuff done

[VoskCoin]

how many intake vents you all think I need for 3 1500 cfm (4500 cfm) exhaust fan?

[btcgolong]

Alright so I've gone to 240v w/ metered PDU l6-20p wall plugs on 30 amps double pole

Curious about the solar, how does it rate, can it move enough air?

Anyone try this?

Also, I'm researching now, but a solar powered gable end vent would be nice and easy to install.
