PSU Problem?

Zangoose · 24 Dec 2009 at 23:51

Just got a OCZ Stealth X Stream 600W psu. When i turn my computer off a noise comes from my psu. I can stop it by switching the On/Off button on the back. Should i be worried about this?

Depends what the noise is really.

Some coil whining...
5V standby is always on when PSU is connected to wall and PSU's power switch isn't on off position.

So nothing to worry about then? It goes when you switch the switch at the back. But comes back when its switched on. Although you can't hear it when the PC is on.

Maybe just little loose wire in coil or mobo drawing power from it at just right space for resonance with that 5Vsb tranformer but hard to know for sure.
With that PSU I would be more worried about long term reliability of its capacitors which tend to be some very cheap ones. (although that problem considers also 5Vsb) You can bet that at that price you don't get Japanese caps and especially when maker is FSP.

Cheers for the info.
