If you're running hubs and miners off the supplied power bricks, you're doing it wrong.
Buy a low power ATX PSU, make up adapter cables, run everything off those. The ATX supplies are more efficient, and don't die after a month.

That's great advise for anyone running more than 2 or 3 hubs. The atx psu I modded could handle my load until I exceeded 40 usb erupters. Most PC PSU's only have a 20-25 amp 5 volt bus, they are limited. I use a 5 volt 50 amp Mean Well industrial psu now. The MW runs 64 sticks without generating a lot of heat and it's quiet, and they are cheap.
