In the Controller Dashboard, what does the Voltage Offset option do?

We added a Voltage Offset option for users because each AvalonMiner is different with each other because of the inclusion of so many high performance chips. The AvalonMiners are very sensitive with voltage, so the “Voltage Offset” option is used for tweaking the AvalonMiner’s voltage. If the miner works well, we suggest to not change the voltage.
And, the lower voltage offset, the lower power. So if the miner works well with -2, it just means the miner has better health.

How do I connect a power supply unit to my miner so it is always powered on?

DISCLAIMER: Please make sure to first turn off and keep your power supply unplugged.

You do not need to connect the AvalonMiner to any computer motherboard. Instead, the trick that miners use is to cut a paperclip and fold into a “U” shape. Then, insert one end into the green wire and the other end into either black wire on the normal motherboard connector cable. Use electrical tape to tape up the connection safely.

Then, the power supply on and off switch controls the power on or off for your power supply.
