My system is:
q6600 @3.42
P5Q Deluxe
3*7200rpm SATA HDDS, 2* 74 gig Raptors
HD4870 (Possibly another one in crossfire)
TT 750 watts (2 years old)
2 optical drives
5 120mm fans

Here's the question back when I had a 8800gtx in this comp at high fps the PSU or gfx card would make buzzing noises. For the most part I ignored this as everything was stable and there were others on the net who experianced same thing with no ill effects.

EDIT: Mostly it just makes screeching noises whenever the gfx card is stressed and the fps is high. Its a lot quiter with the HD4870 but still just audible over the case fan noise.

Anyone know of the issues that the TT toughpower supplies had or what could be causing it. This mostly happens with graphics cards requiring power connectors (2 more so than one) The other supply I have which is a RX2 550 has no such problems with the same cards.

Its just the PSU. Its probably one of the coils in the PSU that is vibrating under the heavier load. I doubt there is anything wrong with the PSU. But if the noise bothers you then replace the PSU.
