The EVGA SuperNOVA NEX650G 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 NEX650G 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 EVGA SuperNOVA NEX650G is extremely efficient and comes highly recommended. The actual efficiencies for this PSU are 87.55%, 91.10%, and 89.85%, for loads of 100%, 50%, and 20%.
The EVGA SuperNOVA NEX650G 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 NEX650G 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.
