Title: WTS CoinTerra IV "2/TH" (more like 1.5-1.8TH/s) miner in Silicon valley/Bay area
Post by: gmaxwell on April 02, 2014, 10:31:03 PM
Greetings. I had a much delayed CoinTerra IV show up without prior notice... and while I'd love to add it to my collection— the CT units are awesome on P2Pool— I'm currently out of room.  The unit is new-in-box and located in Mountain View, California.

I'm looking to sell it immediately for USD (in person) or BTC.

It looks like these units-in-hand go for about $8k on ebay, but I'm willing to negotiate. An ideal buyer would be willing to pick it up tomorrow, in person, in mountain view and pay cash, basically minimizing my time in fussing with it.

PM on here or reach me at nick gmaxwell on freenode, or via email at greg<at>xiph.org.

(Also— if any in-person buyers is interested in some historic early batch 1 avalons that mine at about 80GH/s, feel free to inquire. :) )

Are these things able to plug into standard residence wall outlets (110v 15-20a)?

They do plug into standard residential outlets but require either a dedicated 20 amp circuit or 2 separate 10 (or 15) amp circuits.

Yep. There are two computer power connectors on the devices, which can be fed from one or two 120 or 240v citcuits.

I have another CT unit running in my apartment already (as well as a number of other miners). Keep in mind these devices are a bit loud in terms of a residential setting (they're about as loud as you'd expect a typical high performance rack-mount server to be), especially in a warm room when the fans fully spin up.

The CT miners draw close to 2KW (across both power cables)  at full speed. Typical US residential power wires circuits with 15 amp breakers, so you need to spread them across two circuits to avoid tripping the breaker. You can run them at lower speeds to lower their power usage, but obviously thats not how you want to run them long term.

Since it didn't make sense to have it just sitting here while I arrange a sale I went ahead an powered up the unit, but have to keep it at the lowest power level (and had to slightly downclock some of my other miners) to avoid tripping a breaker here. :) Runs fine.
