Multiple PSU failures

para08 · 27 Nov 2009 at 01:03

I seem to have a weird annoying issue with PSU's failing and i'm starting to wonder if it's something i'm doing wrong. Since August 2008 when I built my PC i've had 3 PSU's fail, all lasting roughly a few months each. I am now on my 4th.

What i'd like to know is has anyone else experienced this kind of problem? and did you find a cause? or can it really be just a case of plain bad luck? What kind or checks should i be doing to rule out all other possibilities?

Any advice appreciated.

i've never heard of a case like this. but personally i would try a different socket. pay attention to the hardware inside the case, check if you can find any stain marks on your motherboard, gpu or other pieces.?

what PSU are you using?

What PSUs though?

its all about the quality

there is a huge difference between a £10 PSU and a £100 psu

especially if its a £10 1000W power supply! Those are the killers.

Let us know what hardware you have in your PC as well, so we can tell if you're using the right power rating.

i've tried different sockets and also use surge protection, i doubt it's anything to do with that anyway as i never had problems with previous PC's on same socket. Also checked motherboard and found no marks anywhere, capacitors look all good. I'm really confused.

The first PSU was a Corsair HX620, the 2nd another HX620. Then when that died I changed to BeQuiet 650 which eventually died and now i'm on my second BeQuiet 650. Both have excellent reviews which is even more confusing.

At least BeQuiets don't have such excellent insides.
Caps are from grab bag and often include cheap unreliable quality CapXons.

But still there's plenty of reason to at least consider other reasons...
Like are outlets grounded?
(and electric installations of house in good shape or from stick&stone era)

Sounds like to me its the wiring in your house. my parents victorian house had wiring done in the 50s and it used to trip all the time and have blown some equipments (tvs and hoovers were favourites). They got the wiring redone to modern standards quite some time back and lo and behold nothing unfortunate has ever happened since. Get yourself a surge protector or two.
