Corsair psi overload

[The321]

What would happen if I draw too much power from my vx450w corsair ?

Bad things

If its well designed, it should just turn off.  Although they will usually run okay within a certain percentage over their quoted output limit.

If its poorly designed, it might continue to work fine also but run hot or your PC become unstable as the voltages could drop below specification.

If its really really badly designed it could emit the magic smoke or even fry your machine due to erratic output, but that is somewhat unlikely from a reputable brand.  Although even a good-brand can burn out once they get old due to the capacitors aging and no longer able to maintain its design specification.

@Alex Atkin UK it's a corsair vx450w from corsair soo It should turn off ?

If they are all made to the same quality, it seems it could handle 570W.

That does depend exactly which voltage rails are being pushed though.

 

I believe this is a reason good brands over-build, so that in almost all scenarios you can pull the rated output, even if some rails are being pushed slightly over their sticker rating, others will still be under.

Now should you do it?  Probably not.  But if all its protections are working correctly it shouldn't cause any short-term problems while you save up for something more powerful.

 

What makes you think you are overloading it in the first place?
