The RM850x power supply has a maximum wattage output of 850W. This should run most PC builds with ease, but might not be enough for power hungry graphics card setups such as SLI or Crossfire combinations. 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 RM850x has an 80 Plus rating of Gold. This means the PSU operates at average efficiency levels of at least 87%, 90%, and 87% for loads of 100%, 50%, and 20% respectively. Gold is the second-best 80 Plus certificate available, and as such the RM850x is extremely efficient and comes highly recommended. The actual efficiencies for this PSU are 87.82%, 90.77%, and 90.24%, for loads of 100%, 50%, and 20%.
The dimensions of the RM850x (LxWxH) are 180cm x 150cm x 86cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.
The RM850x 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 RM850x 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.
