PSU Noise

[andy04]

My PSU makes a high pitch low volume noise... it started happening after a Thunder strike which rebooted my comp. The pitch keeps changing from time to time depending on the load but its not loud enough to bother me. Is this noise something serious enough to change the PSU? It has been around 3 months now and I have never experienced any problems what so ever...

I am continuing to this old post because I saw a post with a similar problem and finally his PSU gave up... I have the same question - recomendation... But I have different priority. My budget is not tight.

It seems that all manufacturers have had bad days... So which is the most reliable PSU today. I need one with 500w or greater (which hopefully will serve my needs for the next 3 years or so).

Best deal in a quality non-modular=Silverstone ST50EF-Plus 500W.
More money but one of the best quiet builds, non-modular, Seasonic S-12 500W.
The very well reviewed Corsair HX-520, semi-modular with a 5 year warrenty.

You could get by easily with a 400 watter but you stated you wanted something for future needs.

are cables/wires the only things different in modular and non modular PSUs ?

The modular PSUs have detachable cables so you can set-up only the ones you use...makes less cable mess. Another highly regarded brand is http://www.pcpowercooling.com

man... they are expensive... are they really worth the money? are they that much reliable ?

Modular PSU's have different circuitry inside them a lot of times. Honestly, its just a nicety Modular cabling isn't necessary.

So far I have found there to only be 3 very reliable Modular PSUs: Seasonic M series, Antec Neo series, and the Corsair series. Seasonic being the best and Corsair very close as they both run off of Seasonic parts and design.

PCP&C is unnecessary, especially for your system. I would recommend a 500 Watt Seasonic power supply. Quiet and one of the most reliable PSU's out there. If you don't like it for some reason then Fortron, Antec, PCP&C, Zippy/Emacs, Silverstone, Corsair (etc...)).

As for the high pitched squealing noise, my best guess without hearing it is just normal capacitor whine. Why it became audible after the thunderstorm? Coincidence? I honestly wouldn't worry about it unless you begin to notice power fluctuations across the rails.

Do you have the computer directly plugged in to an outlet with no UPS or surge protector?
