GFX Card squealing

[BahBah]

Hi,

When my GFX card is under high load in for example Bioshock, it squeals. I've had that before prior to me getting a Corsair 520W PSU because I understand that noise is a sign of being underpowered.

I now have a Q6600 (not G0), 4Gb RAM, a WD 500Gb drive, and the 8800GTS. Apart from 3 USB devices - UPS, keyboard, and mouse - that is all I have running on the system.

Is it right that the Corsair should be struggling like that ?

Thanks

Thanks very much for your replies guys. It has put my mind at rest a little. Still can't believe how much power these components need nowadays.
