With efficiency at all times at or above 80% and power factor higher than 0.90 the IN WIN Commander 1200W meets the requirements of the claimed 80 Plus certification. The In Win Commander 1200W performs very well in this section with no real problems to report. Onward....

 

AC Ripple On DC Outputs:

 

The AC ripple/noise levels on the In Win Commander 1200W rails are marginally higher on a mains supply of 230VAC but only by a few millivolts. The oscilloscope photographs and figures given below are all for 230VAC.

 

AC Ripple On 3V3 Rail at 230VAC

Oscilloscope settings: Amplitude = 10mv/div, Timebase = 10uS/div

 

AC Ripple On 5V0 Rail at 230VAC

Oscilloscope settings: Amplitude = 10mv/div, Timebase = 10uS/div

 

AC Ripple On 12V1 Rail at 230VAC

Oscilloscope settings: Amplitude = 20mv/div, Timebase = 10uS/div

The AC noise/ripple levels on all the rails fall within the limits set by the ATX12V V2.2 specification and the IN WIN Commander 1200W therefore gets an overall pass in this section. No problems here so let's move on.....
