The Cooler Master eXtreme Power Plus 650W power supply has a maximum wattage output of 650W. 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 Cooler Master eXtreme Power Plus 650W does not appear to have an 80 Plus certificate, so make sure it is as effective as you need it to be if using it in a build.

The dimensions of the Cooler Master eXtreme Power Plus 650W (LxWxH) are 14cm 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 Cooler Master eXtreme Power Plus 650W 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 Cooler Master eXtreme Power Plus 650W 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.
