I had built a machine awhile back, i have a Lian Li case, the processor is Intel Q6600 2.40 ghz with 8GB DDR2 ram. The motherboard is Asus P5n-D and the video card is PNY GeForce GTS 250. This machine has always been loud as h*ll.....When I built this machine, a friend of mine suggested a Corsair TX750W power supply. To be honest, I will never claim to be an expert on hardware, but not sure if this is overkill? the machine is loud to the point that its annoying. If it's a great power supply, I'll leave it but if someone has a better recommendation, I'd like to hear it. I guess it could also be the fan on this Lian Li case?
