I have Antec Sonata II with low-noise SmartPower 2.0 450W which is about to die. I have quite old system, so I don't anything too powerful, yet quality and silence are important. Rough system's specs: CPU: AMD Atlon (venice) 3500+ MB: Gigabyte GA-K8NSC-939 nvidia nForce3 250Gb RAM: 2x1G crucial Storage: 1sata+1pata HDs; 1sata+1pataoptical drives. Video - Radeon X850 - AGP8x PSU requirements: About 450W, quality!, silent. Molex connectors is a must. I am considering 4 PSUs. Please help me to choose or suggest anything similar. 1.
