I woke up this morning and tried to turn on the PC and nothing happened.

I have an Antec SmartPower 2.0 450watt PS.
It emits a slight buzzing, or more a soft whistle and nothing happens when i pres the power button. Tried unplugging and the buzz goes away. Same when i turn off the power switch on the back of the PS.

Am I correct in thinking its dead and i need to start RMA? Anything i need to try or that i am missing?
There were no storms and its plugged in to a surge protector.

Oh crap! My antec sp400 is making the same buzzing noise, but my pc still can boot. Damn, this is not a good sign for me.

Oh yea, I think your ps is dead.

This same thing has happened to me twice now with the SP450. It came with my SonataII case. First time was about 3 months ago. Just wouldn't power on the next morning. I reseated everything, nothing. RMA'd it. Replacement SP450 worked great until 2 days ago, and now the same thing. If I am still under warranty I am going to try to RMA again, but I have already ordered a new PSU. I am not using a SmartPower anymore. I will say my TruePower430 has worked flawlessly for 2 years, so maybe its a SmartPower series problem. Also the voltages were not nearly as stable as the TruePower.
 
Reason being why I will never go Antec psu's (or maybe antec anything) again
 
My SP 500 has been working perfect for a year now, sorry to hear of your luck but its not common.

I truely think you jinxed me, my SP-500 just 1 hour ago started making this strange audible noise and the exhaust is alot warmer than normal. This isnt even under load either, RMA time I guess. I already ordered an Enermax 460w to replace it, as I cant be without a pc for more than a day haha. Sucks too, I had alot of faith in these things but Antec SmartPower series have something going on.

Almost antec everything have something going on :(. NeoHE seems to be doing pretty well though. What kind of Enermax did you get? Noisetaker or Whisper.
 
Thanks, from what ive seen it is exactly what I wanted. No bling, all quality, nice +12v rails.
 
Strange noises
MICROPHONICS

Semiconductors are not prone to microphonics themselves, but some other circuit elements can cause them. One case is the inductor used in some LC oscillators, particularly in the radio-frequency range. This effect can sometimes be minimized by firmly anchoring each turn of the coil with special adhesives such as RTV. Phase-locked loop circuits can be sensitive to microphonics generated by the physical movement of the inductor used in the oscillator.

Capacitor Failure Patterns in DC Circuits
The majority of capacitor failures, perhaps 90%, involve the internal shorting of the capacitor. Once shorted, the capacitor frequently causes power-supply overload, often causing the power supply to blow a fuse or other wise fail. In less drastic failures, the capaitor no longer functions to isolate DC voltages from one circuit to another. If power is still applied, this failure is easilly determined with a DC voltmeter since there is a zero voltage drop across a shorted coupling capacitor.

...If the electrolytics are bad, the oscillation can be a squeal...

Got Fuhjyyu?

Happened in my True 430...



IIRC


Jonny you asked Antec if they stopped using the Fuhjyyu caps right?
