For what it's worth I tested my two sammy 1 PSU box power usage. 212W from the wall. This is on an older Antec Smartpower 2.0 400W (or is it 450W? I forget) power supply with no PFC and definitely not 80+. I think it is mid-70's efficient. Power factor is an abysmal 0.65

With an 80+ unit I could see it pulling 200W or perhaps a tad less from the wall.
