We all know that computers rely on power to operate. However this same power can damage your computer sometimes irreparably.

And despite the fact that people are aware of the danger, most do not know the measures you can take to protect your computer.

Sam A. Sewanyana, an IT technician, explains that computer power damages are caused by short circuits and unstablised power. However, the power distributors can be the remedy to the problem.

Computers are connected either to power strips or battery powered backups. These power distribution channels are different.

Power strip

This is a simple surge protector with multiple outlets to accommodate all your electrical devices. A power strip is also known as a plug board, power board, and power bar. It attaches to the end of a flexible cable and allows multiple devices to be plugged in.

Many power strips have built in surge protectors described as electrical line conditioners. These protect the PC from a sudden high current, an important feature to keep your PC free from surge damage. Some have a volt meter indicating power consumption levels.

Battery powered backup

It is a secondary power supply that provides power in the absence of the main power supply. An electronic device which utilises a backup battery will normally get its power directly from a sustainable alternating current (AC) source or solar cells (DC).

The backup battery will power the circuit only in the event of failure. The battery is otherwise charging from that same primary circuit.

This protects you from power surges as well as power loss. Power loss often goes unnoticed and damages your PC’s internal parts.

The device also has a feature that may condition the incoming power to your computer. In simple terms, it regulates the power it feeds your computer.

Some of the more advanced models come with software that enables you to programme the computer to turn itself off before the batteries in the backup run out. This feature makes battery backups more desirable for uninterrupted power supply (UPS).

The deciding factor between these two product lines is cost. Surge protectors are inexpensive and power backups can range from moderate to very expensive. You get what you pay for but do not go cheap on power protection.

The lowest power cost for strip is Frw3,000 and Frw60,000 for the power backup. Do not be caught unprepared. Replacing a surge protector or battery backup is far cheaper than having an entire computer system.
