Power failure damage?

FunkyFeatures
Go to solution Solved by Aniallation,

Hello, about 2 minutes ago the power went out, turned off everything, 10 sec later it came right back. Can this harm my pc components, or only the data?

The PSU is a half defect EVGA 750G2 soon going for a second RMA.

No, nothing will be damaged aside from whatever you were doing that didn't save.

Well, all I did was about to post on this forum, so I guess I'm safe. Thanks for clearing that up though, heard myths about powersupplies killing components under power failure.

By power failure that could mean two things,

A ) The power to the house goes out (harmless, as said above your data might not be saved)

B ) Power Supply Failure, Normally with a good PSU this is harmless but if you own a cheap PSU then it could send far too much voltage through the wires and fry some hardware. This is one of the reasons you never buy cheap power supply's.

Very low quality PSUs can do that. I've seen a Gateway desktop that was in my house light on fire and shot sparks into the case... Then everything inside caught on fire..

Loss of power (like say, accidentally kicking the power cord out of it's socket)  is harmless.   Other than losing whatever data is in RAM nothing much happens.

 

But more serious problems can occur when it is a power failure at the service level.  Those don't happen for no reason,  they usually require some sort of negative event - a lightning strike, breakdown of equipment, a squirrel gnawing through line insulation etc.

 

When they happen the system goes into failure mode and tries it's best to shut things down cleanly.  But there are no guarantees, you can get spikes that will overvolt/overcurrent  components - effectively destroying them, or less serious transients that can lead to data corruption, which can be a real problem if the device was in the middle of writing to the registry or doing something else equally critical.

Sorry, not good at english. What exactly do you mean when it is at service level?

Wiring through your house or at the transformers down the street

Well, I guess it was just locally, as in the relay turned off and back on.
