The EVGA SuperNOVA 1300 G2 power supply has a maximum wattage output of 1300W. This should be enough to run multiple of even the most demanding of graphics cards with SLI or Crossfire, although it is worth double-checking if purchasing a particularly power-hungry graphics card setup. 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 1300 G2 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 1300 G2 is extremely efficient and comes highly recommended. The actual efficiencies for this PSU are 89.25%, 91.75%, and 91.09%, for loads of 100%, 50%, and 20%.

The dimensions of the EVGA SuperNOVA 1300 G2 (LxWxH) are 15cm x 20cm x 8.6cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.

The EVGA SuperNOVA 1300 G2 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 1300 G2 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.
