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

CB, CE, TUV, C TUV, LVD, RoSH & 80 Plus Gold

Power supplies for computers work by converting mains AC to low-voltage regulated DC power, allowing internal components to be powered and function correctly. They also help to maintain air circulation and prevent components from overheating.
