The Rosewill Quark-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 Rosewill Quark-1000 1000W 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 Rosewill Quark-1000 1000W is exceptionally efficient and comes very highly recommended.
The Rosewill Quark-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 Rosewill Quark-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.
