The verdict
This is the one for a build where silence matters most. HWBusters called its noise output dead-low, and PC Games Hardware gave the 1200W model its Silent award.
Both reviews also found excellent efficiency, with a Cybenetics Titanium rating, and very stable voltages. HWBusters praised its build quality and called it a major improvement on the previous model.
It lacks fan failure protection, and HWBusters found the 3.3V transient response only mediocre. Expect to pay more for it than for a Gold unit.
