Seasonic has been making top notch power supplies since I got to know them last year. With their new Seasonic X-750 750W power supply, not only is this power supply 80Plus Gold rated, but also comes with a silent fan. The PSU's fans don't kick in till the user reaches 20%±5% load, and it maintains a 16dB(A) acoustic noise level until it reaches 50% load. From that point on the fan speed begins speeding up from 16dB(A) still maintaining low acoustic noise. The Seasonic X-750 750W power supply is also 100% modular which makes it very easy to install and makes it very convenient to only use the cable leads you really need for your system.
