Ultra-Quiet PSUs above 600W

600W not enough? Then you must have one power hungry PC! As well as being able to power a small town, these power supplies are designed for PCs that are jam packed with components. Most of the PSUs here are supplied with four PCI-E connectors which makes them suitable for powering ATI’s and nVidia’s latest graphics card configured in Crossfire or SLI.

“If you want a quiet pc”

“The Pro Gamer is exceptionally quiet. Early days yet for reliability but it does seem very well built. I dithered for quite some time and asked questions and advice from Quiet PC excellent technical support. It’s much quieter than the Alienware PC.”
