The specs are very solid and in one package: no need to hook up an extra power supply. Now for the specifics of how it runs and more… The shipping gods are fickle, as always. While the box and unit were not damaged, the Beagle Bone Black had jostled partially off the pins causing it not to boot and popping a blade cable loose as well. Once these were secured the S4 powered on with no issues. The LCD tells you the IP address that the miner is on so you can easily navigate to the control panel and add your pool settings and password. As with most Bitmain miners, the initial username and PW is root/root. We highly suggest that you change it to something secure.
The Antminer S4 ships now… which is another thing to consider when purchasing miners. You want to be able to get as much hash power as you can before difficulty increases.
