When in an power outage or lighting storm the PC is susceptible to data loss or accumulation of damage to the component. Files of important documents or software could be corrupted due to such an occurrence.
One of the most efficient ways to counteract this loss of data would be with an uninterruptible power supply (UPS) or also known as a surge protector. this piece of technology is often complemented with a PC as without one would be similar as to driving without insurance. There are no downsides of having one and just having one would be of great benefit to the user.
Many online sources state how having a surge protector is highly recommended as PC and computer equipment are highly sensitive to power surges. Having a surge protector that only cost a fraction of a PC can save that $1,000 dollar PC from being destroyed or damaged and will save the user more in the long term.
Overall, a surge protector although not a component of the PC is highly recommended. Without it the PC is machine waiting to be broken from a thunderstorm or blackout. And in addition, a surge protector can help ensure that even during a blackout your PC can still stay connected with the internet to do work or such. This duality of benefits ensures that anyone who builds or gets a PC should highly consider obtaining a surge protector.
