Reviews about the Silencer Mk II 650W

"The PC Power & Cooling Silencer Mk II 650 W can really deliver its labeled wattage at high temperatures. Efficiency was high, between 83.6% and 87.3%. If we tried to increase one amp at any given output, the unit would shut down, showing that one of its protections kicked in, which is always the desired behavior. The maximum amount of power we could pull from this unit matches precisely the peak wattage advertised by the manufacturer. The new PC Power & Cooling Silencer Mk II 650 W is a very good power supply, presenting better performance than practically all 650 W power supplies we’ve reviewed to date."
