@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%.

I dont have any of the units set up on a test bed right now but they are DOE Level VI rated at 88% efficient. They have less than 1mA of power leakage so most of the efficiency is lost as heat but at 88%, unless you buy a meanwell or a titanium PSU, you wont get better quality. When I get to the shop tonight, Ill see if i can run a few tests for you.  Sidehack may also have a quick answer, we sent him a few test samples when we brought them into the states.
