Paranoia

[Savage Pvpman X D]

Hey all,

So I recently built my first PC, and a question I'm having is should I leave my PSU (a Corsair TX650M) on after shutting down my PC.

 

I'm not bothered by the additional cost nor the red light from the motherboard when the PSU is on.. My main concern is fire.

Can a PSU catch on fire when the PC is off, but there is small amount of power still running through?

 

Replies/Feedback is appreciated,

Thanks,

- Tom

 

P.S. Yes I know I'm paranoid, but i don't want to have to turn it on/off every time I turn off PC, plus it's probably not healthy constantly doing so...

Yes they can.

You should be fine, but if you're really paranoid, keep your psu connected to a surge protector or ups. Anything that draws or uses power inherently has the risk of catching fire or blowing up. The chances of that happening nowadays, however, are extremely minimal. Nothing should catch on fire so long as you aren't keeping the pc in some extreme temperature condition. Also to note, the highest chance of failure will likely be a capacitor blowing up within a psu. On the off chance that one does blow (very very unlikely given that the power load from the psu is basically nothing), there's a good chance you'll smell smoke, but there'll be no fire.

Don't see it effecting "health". Unless you mean longevity of the switch itself. 

If you are  asking about this, I assume you already unplug and manually turn off everything in the building already.

Just I've heard about rumours about people damaging their PC because of constant on / off of there PSU, due to surges.

 

I'd rather be safe than sorry, especially since this isn't my market of expertise ;p

Well if the psu is so low grade to not have surge protection maybe. Pretty uncommon to be turning the psu off anyway, unless you are constantly testing or building. Even then highly unlikely.

Depends on how long you are thinking about it being turned off.

For an hour or two, no.

For a day or two, yes

For your vacation: Absolutely!

So IMO it makes sense to do that before  going to sleep _AND_ afterwards going to work, so a total of 12-16h disconnected or somewhere around 1/2 to 2/3 of a day.

If it is shorter, no.

Probably not if your line isn't totally messed up...
