Power losses and spikes can damage the electronic component in your computer and frustrates you to no end when that GBP/SGD trading opportunity or hours of work in progress is lost from an unexpected shutdown. Motor-driven components such as your hard disks are especially prone, causing corrupt data and system errors.
While a UPS (Uninterruptible Power Supply) is not required in a complete computer system, including one as part of yours is always wise. A reliable supply of electricity will preserve the life of your high-end computer and everything in it – saving you a lot of hassle from trying to repair your computer or recover your irreplaceable photos and documents in the first place.
How UPS Works?
A UPS is primarily used to provide a backup power source to important desktop computer hardware components – the CPU and the monitor – but other devices can be plugged in for backup power as well, depending on the size of the UPS. The UPS also act as stabilizers, ensuring that the electricity flowing to your computer is free from voltage drops or surges.
Standby UPS or On-Line UPS?
Generally, there are two different types of UPS:
- A standby UPS monitors the power that’s coming into the backup power supply. It only switches to the battery when it detects an issue. This is the most common type for Personal Computers.
- An on-line UPS, on the other hand, is always providing power to the computer, which means whether a problem is detected or not, the battery is always the computer’s source of power. On-line UPS is more expensive than the standby model, but offers superior power protection that is important for small business, web, and departmental servers.
How Much Voltage and Watt to Get?
To determine how powerful of a UPS you need, first, use the eXtreme Power Supply Calculator to calculate your computer’s wattage requirements. Take this number and add it to the wattage requirements for other devices you would plug into the UPS. Take this totaled number and check with your preferred manufacturer to get your estimated battery runtime when you lose power.
