High Power EP-550S 550W compatibility review

The High Power EP-550S 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 High Power EP-550S 550W has an 80 Plus rating of Bronze. This means the PSU operates at average efficiency levels of at least 82%, 85%, and 82% for loads of 100%, 50%, and 20% respectively. Bronze is the fourth-best 80 Plus certificate available, and as such the High Power EP-550S 550W is very efficient and is a decent PSU choice. The actual efficiencies for this PSU are 83.79%, 86.43%, and 83.82%, for loads of 100%, 50%, and 20%.

The dimensions of the High Power EP-550S 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 High Power EP-550S 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 High Power EP-550S 550W is designed for low volumes, meaning that its constant drone while your PC is on would be less noticeable - ideal for those that prefer silent environments.
