PSU's / Power Supplies

A PSU (Power Supply Unit) regulates and delivers the power to components in a PC. The more components in a PC (i.e. hard drives; CD / DVD drives; fans etc), the greater the power required from power supplies

A standard power supply can typically deliver around 350 Watts.

Variations of power supplies used in desktops and laptops:

- AT Power Supply: These are an older model but are still used in some PCs. They have two 6-pin single inline connectors which plug into the motherboard right next to each other.

- ATX Power Supply: ATX (Advanced Technology Extended) was created by Intel in 1995 and was the first big revolution in computer casing and motherboard design in many years. A full size ATX board is 12” width x 9.6” length and boasts a 20 pin dual-inline connector which plugs into the motherboard. These are commonly used in many of today’s power supplies.

- ATX-2 Power Supply: These are even more technologically advanced standard power supplies which tend to be in modern desktops and laptops. Further to the features offered by the ATX model, the ATX-2 has a 24 pin dual-inline connector which plugs into the motherboard, providing further power to components.
