HEC 550TB compatibility review

The HEC 550TB 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 HEC 550TB 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 HEC 550TB is very efficient and is a decent PSU choice. The actual efficiencies for this PSU are 83.50%, 86.77%, and 85.37%, for loads of 100%, 50%, and 20%.

The dimensions of the HEC 550TB (LxWxH) are 14cm x 15cm x 8cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.

The HEC 550TB 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 HEC 550TB 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.
