I am thinking these are perfect....

http://www.tripplite.com/pdu-power-distribution-unit-30a-1u-c19-c13-outlets-nema-l6-30p-plug-208v-240v-single-phase~PDU1230/

I have 3 45u racks. Which were bought to accommodate rack mountable gear. Example.. I bought 10 1M5 miners from ltcgear and they were never delivered. I have since traded them in for shares and he pays me weekly for them. Also I bought 2 x3's which would have mounted but now I am going a different direction. I am looking at a way to incorporate the racks to marto miners. Sadly, till I have my hands on them, I cannot make anything. Sad

Keep it coming guys, your advice is more than appreciated.

It's by no means a permanent install and not to code, but for temporary setup (that's been running fine for two months) I ran a 20A breaker, 12/2 wire (line, line, GND) into a 3-gang of standard 5-15R outlets. They're not rated for 240V but everything's working fine and the current from a single PSU shouldn't overload contacts, especially if you operate around the midrange of the output instead of peak (and by "peak" I mean 120% rated that it can actually do). If I'm thinking right, 50 martominions across 14 PSU will draw around 6.5-7A per PSU on a 240V line so basically any consumer socket will work. If you want to go fancy (and probably more reliable) use that guy's PDU, otherwise hit up the Home Depot and make your own for about $20. If you're using 30A circuits though, definitely run at least 10AWG wire.

You'll be looking at drawing around 100A of 240V to feed all those miners. Make sure that's possible with the power service you have available.

Thanks again guys for the input. Here is what I got today. My electrician suggested instead of outlets why not run the cable directly to the connector plug and you can move it as needed. He also had me buy the SJ instead of SO that way it meets code as well. So the 4 30amp circuits should support 16 PSU's if I am reading this right.

Also, My Main Breaker for the house is a 200 amp service. I have already informed the wife that the oven and dryer will not be used at the same time. I am converting my existing 48 gpu farm into 240v as well and will be moving it to another site. My cointerras will be moving as well. That brings up another point. So long as I connect these psu's to the main board of the cointerras, one could run both machines correct? They pull around 500w per board, but I have a dead board so 3 boards should be fine on one PSU instead of the 4 I have now.

Please tell me anything you see as a problem to this point. I still haven't figured out the tripplite situation as of yet. Nor the power cords for the PSU's. What gauge is need for those?

More orders shipped out today. We're waiting on some 18" cable parts to come in but the rest of the orders currently pending should ship out on or before Tuesday if everything goes as planned. After that we'll be focusing on moving and getting the shop set up, especially fleshing out the hosting side and getting benches back up.

As a comparison my home only has 100 amp service from the utility. I'd expect a visit from the police too if you are drawing 100A in your home.

Xcel [I and maybe? nexus99's power provider] actually called us to ask about our power use when we were running 15 ants per apartment this winter, but we also have a bunch of high end cops, but once we told them it was for miners we never heard from them again

Need some help...

I have received my 14 PSU's and awaiting the boards and cables. Sadly, I got no power cords with them, can you please point me in the right direction? I decided to go ahead and set up a new breaker box off my existing running 20 amp. Should I consider 30's? This should assure maximum efficiency. I now need power cords, fans to cool the psu's, and power strips. Any help is appreciated. I am going to be running 50 Marto Miners, and already working on another 50.

Anyone who has advice, please jump in.

If you are running new wiring for this, I would suggest:

30A 240V line (run 10/3 orange wire)

L6-30 twist-lock plug on the terminating end (dryer plug)

A PDU such as this (this is rackmount, they make other form factors): http://www.cdw.com/shop/products/Tripp-Lite-PDU-Basic-208V-240V-30A-4-C19-16-C13-L6-30P-Horizontal-1URM/759513.aspx

Cables such as this: http://www.showmecables.com/product/c20-to-c19-power-cord-1-ft.aspx?utm_source=google&utm_medium=cse&utm_campaign=44-105-001&zmam=49733141&zmac=5&zmas=1&zmap=44-105-001&gclid=CNWzg6bog8ACFaVZ7AodOHEA9Q

Oh, and BTW - to power all 14 PSU's to capacity you'll need fresh 200A service, minimum. I'm basing this off of sidehack's post a few back of each PSU running roughly 12A at full load, if my math is correct.

Anyone have an extra board handy? Sadly I cannot afford one yet...don't have a use for one either, I just want to further develop my 3d printed enclosure design for these and without a unit on hand, it's impossible to test fit.

I will gladly supply anyone with a couple enclosures once complete and the entire process should take less than 2 weeks, including shipping in both directions.

Thanks!

Send me a PM. I'd be willing to send you one of mine to test while i'm on vacation if I can get 2 cases out of it? Leaving tomorrow so I'd need to know today.

Just PM'd you my info. Going to up the ante and throw in a couple R-Pi cases and some other 3d printed goodies as well!
Thanks much, you rock!

Anyone know or have a server that used one of these PSUs? You could look at what direction the air flows in those.

That's a question I don't have an answer for. Likely it doesn't matter, but someone that's studied the layout of an actual BladeCenter might be able to advise better.

I've had one running with a pair of Delta 80mm zip-tied to one side. A lot of folks that used these supplies in high-dense installations would stack two and use a pair of 120mm zip-tied across both of them.

We're looking into feasibility of selling a full kit with 12x 36" cables, the PSU, the board and a pair of appropriately-sized fans in a bundle, so I'll also be doing research on the options here soon.

Yep, the 2x stack with the 120mm fan is one of the options we are mulling, it seems to be feasible especially with the longer cables.

One question tho - is there a more optimal direction to have the airflow? i.e. if the PSU is postitioned vertically with the plug to you, breakout board away from you, does it make a difference in the cooling if the airflow is from left-to-right, or the other way?
