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.
No worries, don't trouble yourself with tests. Upper 80% really great for these little AC/DC blocks, no good way of getting better than that without spending nearly $100 on a real ATX PSU anyhow.
Just put in order for 3, looking forward to seeing how far I can take the Acasis USB hub and my 5 NewPacs.
