The Rosewill CAPSTONE-550-M 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 Rosewill CAPSTONE-550-M has an 80 Plus rating of Gold. This means the PSU operates at average efficiency levels of at least 87%, 90%, and 87% for loads of 100%, 50%, and 20% respectively. Gold is the second-best 80 Plus certificate available, and as such the Rosewill CAPSTONE-550-M is extremely efficient and comes highly recommended. The actual efficiencies for this PSU are 89.52%, 90.81%, and 88.82%, for loads of 100%, 50%, and 20%.
The dimensions of the Rosewill CAPSTONE-550-M (LxWxH) are 16.5cm 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 Rosewill CAPSTONE-550-M 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 Rosewill CAPSTONE-550-M 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.
