Some impressive figures from the Corsair HX750W, which easily meet the requirements of the ATX12V V2.2 specification. The Corsair HX750W also meets 80 Plus Silver, but more on that in the conclusion.

 

AC Ripple On DC Outputs:

 

I have consistently found the AC ripple levels on the DC rails to be more or less equal with a 110VAC or 230VAC mains supply. The results given below are for 230VAC only, but I will continue to check the levels at 110VAC during testing and publish them below if they differ in any way.

 

AC Ripple On 3V3 Rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 10uS/div

 

AC Ripple On 5V0 Rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 10uS/div

 

AC Ripple On 12V1 Rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 10uS/div

Excellent set of ripple/noise figures for a power supply delivering nearly 750W. I was especially impressed with the level on the +12V rail, which is excellent considering it was delivering over 600W.
