I also checked the amps and it got up to 2.x (never saw a three) right now its settled in at 1.60 a . My 620m PSU is rated to 25 amp, is that measuring the same thing?
SO - looks like my Antec 620m is way more than I need right now - by almost twice the power draw.
I'll have to connect this gizmo downstairs and see what the old system is drawing on the 300 Happy PSu.
I would say on average people are probably over shooting by 70-80% on their power supplies because they "think" they need bigger.
