Based on the numbers you posted and a PF of .5. Look at the AC input specs on the power brick, I will bet it's 120VAC x 2A = 240W. Mine here draws 1A to output [email protected] or 120W to output 40W.
Those are of course maximum numbers but it illustrates the loss converting from ac to dc. I'd imagine based on the load on and temperature of the PSU that the PF changes over time as efficiency fluctuates. On Aug 2, 2011 1:49 PM, "Bino Gopal" <[email protected]> wrote:
