High pitched noise coming from brand new Antec PSU.

Thomasj · 09-13-2006, 08:21 AM

I just installed an Antec smartpower 2.0 350W PSU. It is making a very high pitched noise. It only makes the noise when the computer is running. It is not coming from the fans. Is this power supply defective? My previous PSU did not make this noise. Its almost like its the sound of electricity going through it. Any ideas?

If you just it where? online or in a retail store? The only moving parts inside a power supply is the fan blades and fan motor. That's it! Personnally while not having ever heard a noise from the TP models and earlier 300w and 350w Antec supplies over the years the first thing here would be to "return it". Don't even wonder about that. A bad psu gets out once in awhile. It most likely has a bad fan motor there. Get an exchange or refund.

Its not nececairely a Fan.. that PSU might be suffering from an internal short-circuit ( because capasitors can make a high pitching noise too,.. when used well,... err,.. wrong

) . i would go back to where you bought it, and ask for a other one. especially since its new,. i wouldnt mess around with it, and RMA it

Archangel's nailed it, it's not necessarily the fan. 'Coil whine' within the PSU itself is a strong suspect. RMA the PSU if possible.

stupid me... yes.. it can be coils, not capasitors. ( capasitors can make noise, but not that loud, Coils can )

Actually, it is the capacitors that whine as well.

EDIT: I pulled a Mr. Google for you guys so you can see what I'm talking about:

You got the second part correct. Congradulations! I've had caps go "BOOM"! and smoke in your face while testing them.

! was the expression some people had when some bad caps let go and the supply was surrounded in smoke! But "Return ASAP" is the one simple term with any new supply with a problem. (and that's despite what Mr. Google Sirkenin says

he knows i don't even use Google)

I proved right here in the forum that you used Google, ace. We all see it, all the time.

And they do whine first. Then they pop. Consult the link.. You'll see quite a few results for whining capacitors.
