The RS PRO 500 watt ATX power supply features a thermally controlled fan with super low noise, making it ideal for use in a range of environments. The PSU includes long flat connector cables, allowing the unit to be installed with ease regardless of the setup, whilst saving space for components. For enhanced protection, the power supply also offers over voltage and over power protection and short circuit protection on all outputs.

Power supply units (PSU), also referred to as computer power supplies are used to supply power to a range of internal hardware components in PC’s and full-towers. Power supply units can vary in power ratings, input and output voltages depending on the requirements. Power supplies can be installed in a variety of ways via connectors, providing flexibility when computer building. Power supply units are used in computers to supply power to a variety of components such as:

• Motherboard


• Graphics Card


• Fans


• Hard Drives


• Optical Drives
