Testing results (Regulation & Ripple)

 

The electrical performance of the Cougar PowerX 550W power supply is definitely incomparable with that of high-end products, yet we still cannot rate it any better than mediocre even after taking into consideration the level of this product. The voltage regulation is good for a power supply of this class, reaching about 3% on the 12V line and 3.8%-3.5% on the 5V and 3.3V lines respectively. Ripple suppression however is rather poor, with the ripple on the 12V line reaching 84mV at maximum load, about 70% of the absolute limit, and up to 44mV on the 3.3V/5V lines, nearly 90% of the absolute ATX design limit.
