The Antec CP-1000 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 Antec CP-1000 1000W has an 80 Plus rating of Standard. This means the PSU operates at average efficiency levels of at least 80% for loads of 100%, 50%, and 20%. Standard is the lowest 80 Plus certificate available, but with 80% load efficiency minimums, the Antec CP-1000 1000W is still reliably efficient and is by no means a bad PSU choice. The actual efficiencies for this PSU are 81.09%, 84.54%, and 85.08%, for loads of 100%, 50%, and 20%.

The dimensions of the Antec CP-1000 1000W (LxWxH) are 7.9cm x 6.9cm x 4.7cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.

The Antec CP-1000 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 Antec CP-1000 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.
