Ripple Measurements
You will see the ripple levels we measured on the main rails of the HCP-1300 in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

Ripple suppression is Delta's specialty and this unit proves it. All rails registered incredibly low ripple levels under even extremely tough conditions, which shows what Delta's combination of excellent components and great design can accomplish. The HCP-1300 will feed your system components power of excellent quality under all conditions, allowing you to achieve the highest possible overclock if you are a hardcore overclocker or guaranteeing the best possible stability if you are a regular user.
Ripple at Full Load
In the following oscilloscope screenshots, you can see the AC ripple and noise the main rails registered (+12V, 5V, 3.3V, and 5VSB). The bigger the fluctuations on the oscilloscope's screen, the bigger the ripple/noise. For all measurements, we set 0.01 V/Div (each vertical division/box equals 0.01 V) as the standard.
