Desktop PC PSU – Power Supplies @ Matrix Warehouse Computers

PCs’ internal components are powered by a power supply, which converts mains AC power into low-voltage regulated DC power. Switched-mode power supplies are universally used in modern personal computers.

Some PSUs automatically adjusts to the mains voltage, while others have a manual switch to select the input voltage. Power supplies for desktop computers usually comply with the ATX specification, which includes form factor and voltage tolerances. An ATX power supply always supplies a 5-volt standby power (5VSB) to the computer and certain peripherals when connected to the main supply.

Buy Desktop PC PSU – Power Supplies for your Gaming or Personal Computer. Available from our computer stores countrywide or from the Matrix Warehouse online shop.
