Surge defense: Applying the identical machines and protocol we use to test surge protectors, we zapped each UPS with 5,000-volt electrical power surges, measuring the quantity of volts they Allow as a result of.

In all our years of dealing with computers, the vast majority of components failures might be right attributed into the anxiety components factors practical experience through the shut down and startup approach (especially if power surges or blackouts are involved).
