[SOLVED] PSU emits high pitched noise

Derek12 · 07-08-2009, 04:13 AM

I have a new generic (no brand) PSU and it works fine, the voltages are OK but it emits a constant and even high pitched noise.
Should I RMA it or can this be normal in some cases?
Thanks

Power Supply Information and Selection

If its free of dust/hair, rma the unit.

I agree, don't use it any longer, RMA that dude.

Derek12 · 07-09-2009, 07:43 AM

OK I will change it
thanks.

agreed, definetly return it.

at the very least it's advertised as a Silent PSU and you didn't get that.

it may only be a squeaky fan, or it may be a leaking power capacitor heading for catastrophic failure--so don't use it!

Yes in the box " low noise" was marked

I stopped using the computer until the new PSU comes.
What I don't understand, though the voltages were OK and the system was working fine, the noise means that the PSU is likely to fail or is failing?
Many thanks

As Stu so rightly points out, a very good possibility is that a capacitor may be leaking. If that's the case, it will blow at some point, and when a psu goes, it can take other components out with it. It's not worth the chance. Power supplies don't last forever, and that one sounds like it's moved well up the expiry date list.

Many thanks thought it was new

I RMA the generic no-brand PSU and now I bough a Tacens Radix III 420W and it is competely silent, furthermore, the voltage values are far better
Many thanks.
