Cougar is a brand that belongs to HEC/Compucase, originally targeted to the European market. Recently, they started expanding to the North American market as well. The RS series is comprised of models from 300 W to 650 W. Let’s see how the 650 W model fared in our tests.

The Cougar RS 650 W is 5.5” (140 mm) deep, using a 120 mm sleeve bearing fan on its bottom (Young Lin Tech DFS122512M).

This unit doesn’t have a modular cabling system, and only the main motherboard cable is protected with a nylon sleeve. This power supply comes with the following cables:

• Main motherboard cable with a 20/24-pin connector, 20.9” (53 cm) long
• One cable with one EPS12V connector and two ATX12V connectors that together form an EPS12V connector, 23.2” (59 cm) to the first connector, 9.8” (25 cm) between connectors
• One cable with one six-pin and one six/eight-pin connector for video cards, 19.3” (49 cm) to the first connector, 5.9” (15 cm) between connectors
• One cable with two SATA and two standard peripheral power connectors, 18.5” (47 cm) to the first connector, 5.9” (15 cm) between connectors
• One cable with two SATA and one standard peripheral power connectors, 18.5” (47 cm) to the first connector, 5.9” (15 cm) between connectors
• One cable with two SATA, one standard peripheral, and one floppy disk drive power connectors, 18.5” (47 cm) to the first connector, 5.9” (15 cm) between connectors

All wires are 18 AWG, which is the correct gauge to be used.

The cable configuration is compatible with an entry-level product, as it only has two video card power connectors, installed on the same cable. The number of SATA power connectors and their distribution across three cables is excellent for a mainstream power supply.
