Here is a view of the back of the power supply. As you can see, there is a lot of honeycomb mesh to allow for all the hot air produced by the power supply to be pushed out without need for any fans besides the one on top. Also note that there is no voltage selector on this power supply; as it is ActivePFC it will select the correct voltage by itself, so there is no need to worry about doing it manually.
The side of the power supply has the standard specs on the input/output voltages and rails, as well as the typical warnings and certifications. This power supply utilizes just a single 12V rail design so you don't need to worry about high-load items like multiple video cards, etc. With a power supply rated at 1.1kw, it won't be unusual to see lots of tripple-SLI and RAID setups requiring tons of power.
On the top of the power supply itself, or the bottom, depending on how you decide to mount it inside your case, is the large 135mm fan that allows the power supply to run so silently. Nexus doesn't provide much info about this fan, but we do know that it runs at a minimum noise level of 15.5dBA - which will be next to completely inaudible over all the other sounds and fans in your PC case. We can also catch a view of the attached cables and modular connectors, which we'll talk about next.
