Test Setup

Primary Rails Load Regulation

The following charts show the voltage values of the main rails, recorded over a range from 60 W to the maximum specified load, and the deviation (in percent) for the same load range. Tight load regulation is essential for every power supply because it allows for consistent voltage levels, despite changes in load.

5VSB Regulation

Load regulation is loose on all rails but 3.3 V.

Ripple Measurements

Ripple represents the AC fluctuations (periodic) and noise (random) found in the DC rails of PSUs. Ripple significantly decreases the life span of capacitors because it increases their temperature; a 10°C increase can cut into a capacitor's life span by up to 50 percent. Ripple also plays a vital role in overall system stability, especially if the system is overclocked. According to the ATX specification, the ripple limits are 120 mV (+12V) and 50 mV (+5V, +3.3V, and 5VSB).

Ripple suppression is good overall. Still, lower ripple at 3.3 V would be ideal, though. Some oscillations on the 5 V and 3.3 V rails affect ripple during the full load and CL4 tests. The weird thing is that these oscillations disappear with a 110 % load.
