Noises in Antec 300W PSU

My Mom's computer has an Antec 300W TruePower PSU (it has 15A on the 12V line), when I about to place my old TDK 420n 4x DVD+RW drive and install a new eVGA GeForce FX5500 video card, I noticed that the PSU was making a whining noise, of course I know that the noise are the capacitors, but when they start making that noise, that means the PSU will go out eventually?
The computer still runs fine with the new video card (it does require a 250W PSU), but should I be worried about the PSU?

//EDIT: "capacitor +whine" -- first four results on Google would've given your answer.
Its not the fan, the PSU only has 1 fan, and it is in the rear. When you turn the PSU off using the switch in the rear (and the computer is off), you can hear the capacitor discharge, as it sounds sort of like a funky electronic sound.
This comment states that the noise is due to capacitor loads in switching power supplies, and a light load causes the caps to resonate because of change of the switching frequency. I did notice that after everything was in the computer, and I plugged it in, the sound changed from a whine to a buzz.
In this thread, one comments that the sound in a PSU is not normally a good sign.
