The Rosewill CAPSTONE-450-M power supply has a maximum wattage output of 450W. 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 Rosewill CAPSTONE-450-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-450-M is extremely efficient and comes highly recommended. The actual efficiencies for this PSU are 88.52%, 90.64%, and 88.76%, for loads of 100%, 50%, and 20%.
The dimensions of the Rosewill CAPSTONE-450-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-450-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-450-M 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.
