quietest?:Antec TruePower 650 vs Coolermaster Silent Pro Gold or other

[izit]

Hi. I'm after the quietest really. I need 600-700w ideally £60-80.
From a lot of research these 3 seem to be the best.

Coolermaster Silent Pro Modular 600W

Coolermaster Silent Pro Gold 600W Power Supply

Antec TruePower New Modular 650W

Any guidance would be much appreciated. Thanks
