Cougar A400 400W compatibility review

The Cougar A400 400W power supply has a maximum wattage output of 400W. This is a very low PSU capacity, and should only be used when powering a low power 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 A400 400W 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 A400 400W is considerably efficient and is recommended. The actual efficiencies for this PSU are 86.34%, 89.26%, and 86.47%, for loads of 100%, 50%, and 20%.

The dimensions of the Cougar A400 400W (LxWxH) are 14cm 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 A400 400W is not modular, meaning that cables are built into the PSU itself and cannot be taken out and connected back in as necessary. This can result in difficult cable management and consequently a messy build and poor airflow.

The Cougar A400 400W 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.
