Careful on the Amazon power bricks, most are cheap junk in a pretty case. We sell one that we tore down to the bits to verify it was good quality. Has a 3 year warranty and passed all the certification test. You will pay more but you get what you pay for, or you get a fire, its that simple.

We are planning on getting 10A bricks, but its not cheap bringing in a full case of units to sell one or two. The other option like MineFarmBuy said, a good quality PSU if you dont mind the aesthetics/noise of it.

@419Mining,

I'm interested in that power supply, do you know what the power efficiency is for it under decent load like 5-6 Amps?

I'm getting pretty terrible efficiency with the blocks I have, USB meter reporting ~9watts and the thing's pulling 12+ at the wall for ~80%.
