These power supplies are the power supplies we use in our systems, and they are absolutely quiet at low loads (0 dB - no fans) and very quiet during heavy use, come with 7 and 5 year warranties, are highly reliable, and are gold or platinum efficiency rated.

1100 Watt Quiet Power Supply

Energy Efficient

The Nexus RX-1.1K GOLD 1100 Watt quiet power supply is guaranteed to provide you with over 88% efficiency (see graph elsewhere on this page). This means the power supply is using the power it is drawing from the wall outlet more efficiently, and less electricity is wasted. Obviously this is better for the environment and it saves you on your electricity bill. A more efficient power supply also results in a cooler power supply. So less cooling is needed and Nexus is able to make this quiet power supply even quieter...even inaudible.

True Power Supply Silence

By carefully selecting each component, Nexus created the best possible of mix of components to make their power supplies as silent as possible. Nexus quiet power supplies are among the top quiet supplies in the market, when it comes to solid performance at the lowest possible noise level. When Nexus tests the noise level they do this in a ISO-certified noise chamber. The lowest background noise possible in an ISO-certified noise chamber is a little over 15 dB(A). These are the best possible conditions for these tests. What you need to ask yourself, when manufacturers claim dB(A) values near or lower than 15 dB(A) is: "How were they able to measure this?"

Quiet Minded Modular & Sleeved Cables

Messy Cables interfere too much with the airflow inside your PC. The modular cable design allows you to only connect the connectors you really need. Plus all cables are sleeved with a quality black and white X-mesh for a nice clean look.

Active PFC Circuit

Power Factor Correction (PFC) allows the power distribution system to operate at maximum efficiency. Active PFC is technically more complex than passive PFC and matches the overall high quality standard and reliability of Nexus power supplies.

Full Range Automatic

The RK-1.1K 1100 Quiet Power Supply can be used on 115VAC and 230VAC input power. Selection is automatically made no voltage selection has to be set. Just plug in and go.
