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 an important characteristic for every power supply because it allows for constant voltage levels despite changes in load.

5VSB Regulation

Load regulation is quite good, but definitely not topnotch, especially on the minor rails.

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 an important role in overall system stability, especially when it is overclocked. The ripple limits according to the ATX specification are 120 mV (+12V) and 50 mV (+5V, +3.3V, and 5VSB).

For budget PSUs, ripple suppression is good in all tests but CL1. I am not sure for how long, though, since the capacitors on the secondary side are not of topnotch quality. The good thing is that 230 V input won't have them age as quickly as 115 V input.
