What should I look for in a surge protector for sensitive electronics?

Don’t confuse a power strip with a surge protector. For sensitive electronics, get one with at least 1000 joules, clamping voltage under 400V, and response time under 1 nanosecond. Stick with brands like APC, Tripp Lite, or Belkin. Surge protectors wear out after a few years or big hits, so replace them every couple of years or after a known surge. Never daisy-chain them.
