ANTEC HCG850 Extreme 850W 80+ Gold Fully Modular ATX 2.0 Power Supply

The Antec HCG850 Extreme is an 850W fully modular power supply built for enthusiast and high-end PC systems that demand stable, efficient, and quiet power delivery. Carrying the 80 PLUS Gold certification, it achieves up to 92% typical efficiency, helping reduce heat output and energy consumption under real-world workloads. At the heart of the HCG850 Extreme is Antec’s PhaseWave design — a server-class full-bridge LLC topology with synchronous rectification built on a DC-DC architecture. This design, combined with 100% Japanese capacitors throughout, delivers tight DC voltage regulation and low ripple and noise across all output rails. With 99% of output capacity allocated to the +12V rail, the unit provides ample headroom for modern CPUs and discrete GPUs in demanding gaming, content creation, or workstation builds. The fully modular cable system allows you to attach only the cables your build requires, reducing clutter inside the chassis and improving airflow without the tangle of unused leads. An extensive connector set covers virtually any configuration: one 24-pin motherboard connector, two 8-pin (4+4) EPS 12V CPU connectors, six 8-pin (6+2) PCIe connectors, ten SATA connectors, six Molex connectors, and one FDD connector. A 28-pin (18+10) MBU socket and a 16-pin socket add forward compatibility for emerging connector standards. Thermal performance is managed by a 135mm fluid-dynamic bearing (FDB) fan, chosen for low noise, long operational life, and consistent airflow. The Zero RPM Manager feature enables fan-off mode at low and moderate loads so the unit runs in complete silence during light usage, only spinning the fan when sustained power delivery warrants it. Protection is handled by Antec’s CircuitShield suite, which covers over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-power (OPP), over-temperature (OTP), surge and inrush (SIP), and no-load operation (NLO). The unit is rated for continuous full-load operation at ambient temperatures up to 50°C — a specification typically associated with server-grade hardware. Regulatory compliance spans cTUVus, TUV, CB, RCM, CE, EAC, CCC, BSMI, and FCC markets. Antec backs the HCG850 Extreme with a 10-year warranty.
