### ⭐⭐⭐⭐⭐ DON'T BE CHEAP WITH THE POWER SUPPLY!!!
*by B***P on April 5, 2015*

Product performs the way it should. Buyer be ware. . . you need to make sure your getting a 700GH/s unit. The ad says one thing and the indvidual sellers might be selling you a ~545 GH/s unit instead. I received mine and it was a 545 GH/s unit. Not that I am complaining because the power usage is still way low than any other device I have in place. The power supply really makes the difference. DO NOT BE CHEAP ON THE POWER SUPPLY!!!! Get a really good power supply. I am using an EVGA 750 Watt. The orginal power supply I tried was a 650 Watt piece of junk and it really wasn't rated for the full 650 Watts it over heated the power supply. I changed it out to the EVGA and the power is even lower than before.

### ⭐⭐⭐⭐ Good, quiet miner
*by M***F on August 11, 2015*

I purchased a used unit on eBay, but I thought it'd be worth a review for others interested in this product.My unit is rated from the factory for 750GH/s. In ~2hr shifts I get anywhere from 699GH/s to 760GH/s. I did get 801GH/s once, but it's generally closer to the 720-740 range running around 68-70C temp in an ambient between 25-30C.I was using cgminer before, but this requires bfgminer. So I have this running on one machine and my other hardware on a different machine running cgminer. It came with the bfgminer software on a CD, so I just had to copy the folder to my hard drive, create a batch file with my login info, add to my startup directory and good to go.This miner is very quiet. The water cooling works well and the fan provided is fairly silent (especially compared to the water cooling fans on my Habanero). As expected it's burning lots of power for processing so the fan output is fairly warm.My biggest complaint is that I wish it had a fully enclosed box instead of the weird-shaped sled. I have it installed on a shelf in a rack with other equipment and I want to make sure nothing contacts the parts and shorts them out, which is kind of hard to do with everything exposed.For a power supply I bought a dedicated 12V 50A (600W) supply instead of a computer power supply and made my own custom connectors. It also has an output voltage adjustment so I can adjust the voltage to get a nominal 12V at the Monarch connectors. In retrospect I probably should have got a 60A supply so I'd have more headroom, but it so far has been running fine 24/7 with no issues and I don't plan on overclocking. I have since bought a Sentley 750W power supply which is also much quieter.Some people don't understand how to select a proper power supply, so I'll add some useful notes here:- You need check the amount of power provided on the 12V rail. Multiply voltage (12V) times current (xxA) to get the power available on that rail. Here's some useful values:- 50A = 600W, 62.5A = 750W, 70.8A = 850W- Get a supply with a single 12V rail. Some supplies actually have multiple 12V sources, which aren't exactly 12V. For example one could be 11.9V and another could be 12.1V. If you connect both of these to the same miner you potentially create a current loop which at a minimum wastes power and at worst blows something up. Some miners (like the Chilimining Habanero) state it's OK to do this since each connector is a separate power rail on the miner board.- Cabling is important! You need at least 16 gauge wiring on the supply. Even then at 600W the 16GA wires will get warm. The smaller the gauge number, the thicker the wire, the better. You want a supply with at least three PCIE connectors. Ideally each one would be straight from the supply, but in a lot of cases they string two on the same wires. This seems to be OK, but not ideal. Also the shorter the wire length the better. No one specs this though.- Do NOT use splitters that take a single (or even double) 16 gauge wires and split it out to an entire PCIE connector. It's a fire hazard!
