The EVGA Supernova 650W P2 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 EVGA Supernova 650W P2 has an 80 Plus rating of Platinum. This means the PSU operates at average efficiency levels of at least 89%, 92%, and 90% for loads of 100%, 50%, and 20% respectively. Platinum is the best 80 Plus certificate available, and as such the EVGA Supernova 650W P2 is exceptionally efficient and comes very highly recommended.
The EVGA Supernova 650W P2 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 EVGA Supernova 650W P2 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.
