Nexus RX-1.1K 1100W 15.5dB(A) Ultra-Quiet Modular PSU, 80PLUS GOLD

Nexus power supplies are designed to provide a PC with stable and efficient power to guarantee perfect PC performance. Nexus have done their utmost to make this model a perfect match of components and parts in order to give an ultra-high efficiency, stable and quiet power supply which is truly deserving of the Nexus brand name.

Energy Efficient
These Nexus power supplies are guaranteed to operate at over 80% efficiency. This means that the power that they draw from the wall outlet is used more efficiently and therefore less electricity is wasted. Clearly, this is better for the environment and it also reduces your electricity bill! In addition, a more efficient power supply results in a cooler power supply which means that less cooling is needed and therefore it is possible to make the power supply even quieter.

Silence
By carefully selecting each component, Nexus aims to create the best possible of mix of components to make their power supplies as quiet as possible. They are confident that the power supplies are market leaders when it comes to solid performance at the lowest possible noise levels. Nexus test the noise generated by their components in an ISO-certified chamber designed for testing noise levels. It is important to know that the background noise in such a chamber is a little over 15 dB(A)! These are the best possible conditions for these tests and hence you should always be wary when a manufacturer is claiming a dB(A) value less than 15.

Modular and Sleeved Cables
Untidy cables can interfere too much with the airflow inside the PC. The modular cable design allows the user to only use the connectors which are really needed. Plus, all cables are sleeved with a quality black and white X-mesh for a clean good look.

Active PC Circuit
Power Factor Correction (PFC) allows the power supply's distribution system to operate at maximum efficiency. This does not significantly affect your electricity bill but it does reduce energy consumption and therefore uses our planet's resources more carefully. Active PFC is technically more complex then passive PFC and matches the overall high quality standard and reliability of these Nexus power supplies.

Automatic Full Range - Worldwide Compatibility
These power supplies can be used on both 115 VAC and 230 VAC input power. Selection is automatically made, so no voltage selection switch has to be set. Just plug in and go!
