The SilverStone SST-ST1500 1500W power supply has a maximum wattage output of 1500W. 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 SilverStone SST-ST1500 1500W has an 80 Plus rating of Silver. This means the PSU operates at average efficiency levels of at least 85%, 88%, and 85% for loads of 100%, 50%, and 20% respectively. Silver is the third-best 80 Plus certificate available, and as such the SilverStone SST-ST1500 1500W is considerably efficient and is recommended. The actual efficiencies for this PSU are 86.11%, 89.13%, and 86.63%, for loads of 100%, 50%, and 20%.

The dimensions of the SilverStone SST-ST1500 1500W (LxWxH) are 22cm x 1.5cm x 8.6cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.

The SilverStone SST-ST1500 1500W 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 SilverStone SST-ST1500 1500W 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.
