Cougar PowerX 550W Power Supply Review

External Design of the PowerX 550W

The Cougar PowerX 550W PSU

Although the PowerX 550W unit is built inside a typical ATX chassis, Cougan managed to make it unique by simply replacing the cover with one that has the fan guard integrated and, well, is painted orange, obviously in an attempt to replicate the color of bronze. The rest of the power supply is black, which is a matching color, yet orange may not be the color of choice for many. The PowerX is a small power supply, fully compliant with the ATX design guide. All of the cables are hardwired onto the power supply.

Right side

On the right side of the chassis, Cougar simply embossed their company logo; a quick and effective way to enhance the appearance of almost any power supply. The logo however will be visible from a windowed left panel only if the power supply is installed with the fan facing upwards.

Left side

The sticker with the electrical specifications of the power supply covers most of the left side of the PowerX, reminding us of old-school designs. The sticker will be visible through the windowed side panel of almost any case which takes the power supply with its fan facing down.

Front Side

The front side of the Cougar PowerX 550W power supply is perforated, with only a simple on/off switch right next to the A/C cable plug.

Rear Side

As this is not a modular power supply, the rear side of the Cougar PowerX 550W is plain and uninteresting, with only a large holes from which the cables come out of.


This power supply offers the following number of cables and connectors:


Main Connector

Peripheral Connector

Floppy Connector

CPU Connector

S-ATA Connector

PCI-Express Connector



4 Pins

4 Pins


5 Pins


CGR B4-550







Six SATA connectors and 2 PCI-E connectors should be enough for a common everyday system, yet we believe that the 3 Molex connectors could leave a few users frustrated on how to power their 4+ optical drives, fans and auxiliary devices.
