Corsair Employee jonnyguru Posted February 17, 2015 Corsair Employee Share Posted February 17, 2015 PSUs have only very minimal brown out protection. You should not rely on the PSU alone to keep your PC up and running if you have frequent brown outs. You should be using a UPS. Link to comment Share on other sites More sharing options...
nickfusco89 Posted February 18, 2015 Share Posted February 18, 2015 If a UPS is out of your price range, a nice surge protector is only about $20. You need that at minimum. Look for one with over 3000 joules. Link to comment Share on other sites More sharing options...
Corsair Employee jonnyguru Posted February 18, 2015 Corsair Employee Share Posted February 18, 2015 True. But a surge protector only protects against surges. It doesn't protect against brown outs. Link to comment Share on other sites More sharing options...
MGCJerry Posted February 19, 2015 Share Posted February 19, 2015 I would also like to add that your common "household surge suppressor" is not a lightning suppressor like many people believe. A true lightning arresstor has a fat copper cable going directly to a ground connection (your standard home wiring is not lightning rated, typically only rated 600v). Its a hard lesson for a lot of people when I had service calls (Electrician for a decade) when they thought their home improvement or big box store surge strip would save them from lightning strikes. I have seen first hand lightning damage to home direct & line strikes from lightning. Lightning can travel for miles, and at such a voltage where wires are "optional paths" so that tiny watch battery sized ceramic disk in the suppressor doesn't hold much resistance as lightning voltage is beyond ceramic's breakdown voltage. Breakdown voltage is the voltage in which an insulator is no longer an insulator. Another important note to add is that most common surge strips will only take one surge, after that, they either fail in a way where it trips your breaker in your main panel rendering it useless or still functions as a non-surge strip. How can you tell if the surge suppression is still good? There is an indicator that tells you if its working. Some say "protected when lit", others say "not protected when lit". If your surge strip indicates no protection you have no surge protection and should replace it. Link to comment Share on other sites More sharing options...
