When there is a power outage while your computer is on, it can be harmful to the computer. The effects of a power outage can include problems with the hardware, OS boot, and data. To protect your computer from power outages, there is Uninterruptible Power Supply, or UPS, that can be purchased t to protect your computer from power outages.

A UPS is an appliance which is placed between the electrical outlet and computer to isolate the computer from a power outage or power surge. When there is change in the voltage due to a power outage or power surge, the appliance switches to a battery backup. This give the computer time to save data and shutdown. There are many types of UPS that protect from short to long term power outages and different types of power surges.

Types of UPS

– Offline — Offline UPS detects changes in voltage and changes from internal electrical outlet to external battery. The appliance is the cheapest and most efficient type of UPS. Find out if the computer can stand the transfer of the electrical source before using an off-line UPS.

– Line-interactive — Line-interactive UPS detects and changes the voltage of the appliance without the use of battery power with an internal circuit. This saves the battery power in times of power outages. This type has transient protection. However, one of its flaws is that the inverter may cause it to fail when needed most.

– Online — Online UPS is has an internal power supply which supplies the computer with power. This provides a complete protection of power outages. The downside is this type is the highest cost, the least efficient, and noisiest.
