&quot;&quot;According to a primer on lightning by NASA scientists Hugh Christian and Melanie McCook (1), a lightning strike has a peak power of about one million megawatts (MW), or an average over the duration of the strike of about 500,000 MW.&quot;&quot;<br />
<br />
Since Watts=Joules per second, &nbsp;so then if the lightning strike is direct or nearby and takes even as short a time as a fifth of a second that is still at least 100,000 MegaJoules, or only about 5 powers of 10 over the capacity of that thar UPS :-/ so go figure.<br />

The statement that nothing can protect against lightening is slightly erroneous however, since if you put your PC with an independant power source in a faraday cage (a big screened enclosure) then provided you had no external connections, it would be safe, maybe you'd want a modulated laser uplink to your isp tho' :-)

according to surge manufacturers, salesmen, and &quot;dummies&quot; books and &quot;bible&quot; books on computers, 300-360 joules is enough to protect a personal computer, but nothing could protect against lightning.<br />
<br />
But some manufacturers maintain that their 1500 to 2500 joule UPS battery surge protectors can protect against lightning. Is that true?

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
