The Be quiet! Power Zone 1000W power supply has a maximum wattage output of 1000W. 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 Be quiet! Power Zone 1000W has an 80 Plus rating of Bronze. This means the PSU operates at average efficiency levels of at least 82%, 85%, and 82% for loads of 100%, 50%, and 20% respectively. Bronze is the fourth-best 80 Plus certificate available, and as such the Be quiet! Power Zone 1000W is very efficient and is a decent PSU choice. The actual efficiencies for this PSU are 84.92%, 89.35%, and 89.02%, for loads of 100%, 50%, and 20%.

The dimensions of the Be quiet! Power Zone 1000W (LxWxH) are 17.5cm x 15cm x 8.6cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.

The Be quiet! Power Zone 1000W 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 Be quiet! Power Zone 1000W 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.
