You need a switched PDU. Try searching ebay, I recommend APC. Depending on how much power you need, you might want to consider a 208v model with a 20 or 30 amp 240v circuit. You can find a 30amp zero U model on ebay for < $200.

Pretty slick, that can definitely be adapted.

I see you are using the lepa 1600. Did you have to split the load on the rails in any special way to keep either of the two rails from overloading?

Haven't done anything special in that regard. I have 5 of the cards running on the gpu side, and the other running on the aux side (black ports).

It's running in an un-airconditioned garage that hovers around 95f, hottest card gets to 78c

95 is pretty damned hot.  I am lucky that I live in a house with a deep stone-wall basement.  Perfect for chilling wine (if I could afford some) or housing noisy computer equipment.  Even in summer it's maybe 70 degrees down there.

But seriously man - you want to put that nice rig into that hot ass garage?  I would be digging a hole or finding somewhere else I could hide that.  Even if it was at work, or at a friends house (who you would have to pay for power I am sure).  :-)


Yea it is hot but it's been running pretty well so far, I don't think 78c on the hottest card is a deal breaker. I could put it in my office but I rather not pay to cool this monster with the a/c too. I'm going to install a large extractor in the garage that should be able to keep the temp at ambient, (88-72).

Right now they're setup to push, been working pretty well like that, there's a little over an inch between them.

What do you guys think? This is my first try for a rack mount gpu miner. Next version is going to be configured a little different, and it will have aluminum paneling on the sides to direct the airflow.
