The Seasonic Platinum 1050W power supply has a maximum wattage output of 1050W. 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 Seasonic Platinum 1050W 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 Seasonic Platinum 1050W is exceptionally efficient and comes very highly recommended.

The dimensions of the Seasonic Platinum 1050W (LxWxH) are 190cm x 150cm x 86cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.

The Seasonic Platinum 1050W 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 Seasonic Platinum 1050W 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.
