Enermax's new Triathlor lineup of PSUs carry a number of new features to improve upon the Modul82+ lineup that has been selling since 2008. Enermax claims that they are not going for a "blinky poser" style PSU, but rather a "classic black, downright ordinary housing."
Enermax boasts about a rock-stable voltage at any load. What this means is that even when there is 0 W load, the voltages over the 12 V rail, 3.3 V line and 5 V lines will remain stable. (Electrical engineers will argue that at 0 W, there is no current, and you cannot have a voltage without a current.) Technically the so called "Zero Load Design" is able to keep the voltages stable nearing 0 W. Regardless, this is not a flaw on Enermax's side, this is just physics.
The point of the "Zero Load Design" is to deliver the same stable voltages at VERY low power draw, like when the PC is in sleep mode with modern day CPU power saving features and graphics cards with a C6 state. Furthermore the units are based on a 12 V rail design; the two 12 V rails deliver 99 percent of the power, with the secondary voltages like 3.3 V and 5 V being transformed off the 12 V rail.
Integrated into the units is a smart, likely PWM controlled 120 mm fan. The fan can stay quiet at 500 RPM to roughly 900 RPM, depending on the model, up to 50 percent load.
The PSUs are also modular. The primary cables that are permanently attached are thick round cables, while the modular removable cables are flat. The units will come with a generous three six + two pin PCIe connectors.
The Triathlor FC units will come in two versions initially: a 550 W unit and a 650 W unit.
