Cougar GX-S 500 W Power Supply Review
Conclusions
Contents
The Cougar GX-S 500 W is a good 500 W power supply with the 80 Plus Gold certification targeted to the mainstream user. During our tests, it could really deliver efficiency according to this certification at high temperatures, which is great. Positive voltages were always within 3% of their nominal values and noise and ripple levels were always below half of the maximum allowed.
On the negative side, the -12 V output presented a voltage outside the allowed range under light load.
The success of this power supply will depend on its price. At USD 110, the manufacturer’s suggested price, it faces a tough competition from the Rosewill FORTRESS-650 (USD 95, 80 Plus Platinum and 650 W labeled wattage), the Rosewill CAPSTONE-550M (USD 100, 80 Plus Gold, 550 W labeled wattage, and modular cabling system), and the FSP Aurum Gold 500 W (USD 90).
