The Antec HCG-620M power supply has a maximum wattage output of 620W. This is a decent capacity, and should be fine at handling the majority of mid-performance PC builds, but you could find yourself in trouble if you do not make certain of its capability to power any proposed build. 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 Antec HCG-620M 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 Antec HCG-620M is very efficient and is a decent PSU choice. The actual efficiencies for this PSU are 82.90%, 86.38%, and 85.28%, for loads of 100%, 50%, and 20%.
The dimensions of the Antec HCG-620M (LxWxH) are 0cm x 150cm x 0cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.
The Antec HCG-620M 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 Antec HCG-620M 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.
