Cougar GX-S 500 W Power Supply Review

Introduction

Cougar has released a power supply series with the 80 Plus Gold certification, called GX-S, with 400 W, 500 W, and 600 W models. They have two +12 V rails and don’t come with a modular cabling system. Let’s see if the 500 W version, also known as “CGR G2-500,” is worth buying.

Cougar is a brand that belongs to HEC/Compucase, but this power supply is manufactured by Andyson.

The Cougar GX-S 500 W is only 5.5” (140 mm) deep. It uses a 120 mm sleeve-bearing fan on its bottom (Cougar CF-V 12SB-P, which actually is a rebranded Power Logic PLA12025S12L-4).

This power supply doesn’t have a modular cabling system. It comes with the following cables:

  • Main motherboard cable with a 20/24-pin connector, 20.5” (52 cm) long
  • One cable with two ATX12V connectors that together form an EPS12V connector, 23.6” (60 cm) long
  • One cable with two six/eight-pin connectors for video cards, 20.5” (52 cm) to the first connector, 5.1” (13 cm) between connectors
  • One cable with three SATA power connectors, 18.5” (47 cm) to the first connector, 5.1” (13 cm) between connectors
  • One cable with two SATA and one peripheral power connectors, 16.1” (41 cm) to the first connector, 5.1” (13 cm) between connectors
  • One cable with one SATA, two peripheral, and one floppy disk drive power connectors, 16.1” (41 cm) to the first connector, 5.1” (13 cm) between connectors

The main motherboard cable and the ATX12V/EPS12V cables use thicker, 16 AWG wires. The other cables use 18 AWG wires, which is the minimum recommended gauge.

The number of connectors is very good for a 500 W power supply.
