As mentioned, the Antec HCG1000 Extreme is based on Seasonic's famous Focus Plus Gold platform in its strongest form. It's able to deliver 1kW of power from an impressively small PCB, even under oppressive ambient conditions.
There's an LLC resonant converter and full bridge topology on the primary side, while the secondary side hosts a synchronous design and a couple of DC-DC converters for generating the minor rails. The electrolytic caps are provided by Chemi-Con and Nichicon, while the polymer caps come from Chemi-Con and FPCAP.
Antec's cooling fan of choice is provided by Hong Hua. It utilizes a fluid dynamic bearing with a long lifetime at normal operating temperatures, offering quiet operation. Although the fan has a high maximum speed, we never saw it hit 100% duty cycle, even in a 49°C environment under full load.
The album above includes photos showing the HCG1000 Extreme's major parts, while the following video illustrates the HCG1000 Extreme’s internals.
