Nexus RX-8500 850 Watt Review


We’re now on to our third instalment to the PSU roundup here at Tech-Reviews. The Power Supply we have for review today is Nexus’ RX-8500. This 850W unit boasts to be a lot of things: ultra stable, real silent and responsibility efficient. Is it? Well we’re about to find out…

About Nexus

“Nexus Technology BV was established in 2000 by a group of experts on heat conductivity and noise reduction in the computer industry. The founders have build up an in depth knowledge and experience on heat conductivity issues and thermal characteristics by working closely with many of the larger pc manufacturers for several years.”


  • Energy Efficient
    The Nexus RX-8500 power supply is guaranteed to provide you with over  80% efficiency (see graph elsewhere on the box). This means the power supply is using the power it is drawing from the wall outlet more efficient 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 we are able to make the power supply even quieter.
  • Silence
    By carefully selecting each component we aim at creating the best possible of mix of components to make our power supplies as silent as possible. We are confident that our power supplies are the leading the market when it comes to solid performance at the lowest possible noise level. When we test the noise level we do this in an ISO-certified chamber for noise tests. 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 aware when a manufacturer is claiming dB(A) values lower than 15 dB(A). Because how were the able to measure this.
  •  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 mesh for a clean good look.
  • Active PC Circuit
    Power Factor Correction (PFC) allows the power distribution system to operate at maximum efficiency. This does not so much influence your electricity bill but it will reduce energy consumption at the side of the power provider so it is contributing to using our planets resources better and more careful. Active PFC is technically more complex then passive PFC and better matches the overall high quality standard and reliability of this Nexus power supplies.
  • Full Range Automatic
    This power supply can be used on 115VAC and 230VAC input power. Selection is automatically made so no voltage selection has to be set. Just plug in and go.
