Yes, they need some sort of external cooling. I just got my order of PSU's in yesterday. Trying to figure out the best cooling solution, probably going to be some fans with lots of cable ties strapped to the side. Anyone have any functioning solutions that are decent and recommended? |

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? |

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.

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

These mount in the chassis. Not on the server.

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. |

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! |

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.aspxCables 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=CNWzg6bog8ACFaVZ7AodOHEA9QOh, 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. |

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.

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. |
