Cougar CMX550 550W compatibility review

The Cougar CMX550 550W power supply has a maximum wattage output of 550W. This is a mid-range capacity, and should be fine as long as it is part of an equally mid-range system build. Always make sure that a purchased PSU is capable of powering your system. Remember that a higher PSU capacity does not necessarily equate to a higher wattage output and a more expensive electricity bill. In fact, you may find that a higher capacity PSU will function more efficiently than a lower capacity PSU because it is dealing with a lower percentage of its maximum load - that is, it is not being stressed to the same extent.

The Cougar CMX550 550W has an 80 Plus rating of Silver. This means the PSU operates at average efficiency levels of at least 85%, 88%, and 85% for loads of 100%, 50%, and 20% respectively. Silver is the third-best 80 Plus certificate available, and as such the Cougar CMX550 550W is considerably efficient and is recommended. The actual efficiencies for this PSU are 88.40%, 89.47%, and 85.69%, for loads of 100%, 50%, and 20%.

The dimensions of the Cougar CMX550 550W (LxWxH) are 16cm x 15cm x 8.6cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.

The Cougar CMX550 550W is modular, meaning that cables can be taken out and connected back in as necessary. This can make cable management much easier, leading to a less chaotic build, and better airflow.

The Cougar CMX550 550W is not designed for low volumes, meaning that its constant drone while your PC is on could potentially be noticeable and irritating, though this may only be a problem for those that require silent environments.
