I just rebuilt my computer, new motherboard, CPU and video card.
Now it's making a really annoying high pitched whine. It sounds a lot like the whine that CRT monitors and televisions make that most people can't seem to hear, but drives me batty. I think in CRTs it's the flyback transformer that does it.
I think it's the power supply. It's an Antec Truepower 2.0 450W. The thing is, I was using this power supply before and it never made this noise. But the new video card draws a whole lot more power than the old one. Nvidia recommends a minimum 450W power supply for this card.
So could running the power supply closer to its limit cause it to emit a high pitched noise? Is it time to buy a new power supply? It seems to be around 8 KHz, anyone know what a typical switching frequency for a SMPS is?
