Antec HCG850 PRO Platinum ATX 3.1 Power Supply

The Antec HCG850 PRO Platinum ATX 3.1 delivers 850W of reliable power for high-performance gaming systems and workstations. This fully modular power supply meets ATX 3.1 and PCIe 5.1 standards, ensuring compatibility with the latest graphics cards including NVIDIA GeForce RTX 40 Series through its included 12VHPWR GPU cable.

ATX 3.1 & PCIe 5.1 Certified Performance

Formally certified for ATX 3.1 compliance, this power supply meets rigorous standards for reliability and power efficiency. The PCIe 5.1 12VHPWR cable provides seamless support for next-generation graphics cards, delivering stable power for demanding gaming and professional applications.

Premium Japanese Capacitors

Built with 100% high-quality Japanese capacitors, the HCG850 PRO achieves tight voltage regulation with minimal ripple and noise. This component selection maximizes system stability and longevity, ensuring consistent performance under heavy loads.

PhaseWave Design Technology

The PhaseWave Design incorporates server-class full-bridge LLC topology with synchronous rectification based on DC-DC architecture. This advanced design delivers exceptional power efficiency and stable voltage output across all load conditions.

Silent Operation with Zero RPM Manager

The 135mm fluid-dynamic bearing (FDB) fan operates with minimal noise while providing efficient cooling. Thermal sensors activate the Zero RPM Manager, which keeps the fan off during low-load conditions, extending component lifespan while maintaining near-silent operation. The fan only engages when system demands require active cooling.

Fully Modular Cable Design

Complete cable modularity allows you to connect only necessary cables, eliminating clutter and improving airflow within your case. The compact 160mm length fits a wider range of PC cases compared to standard high-end power supplies, providing flexibility for various build configurations.

Industrial-Grade Protection

CircuitShield protection suite includes OCP (Over Current Protection), OVP (Over Voltage Protection), UVP (Under Voltage Protection), SCP (Short Circuit Protection), OPP (Over Power Protection), OTP (Over Temperature Protection), SIP (Surge/Inrush Protection), and NLO (No Load Operation). These safeguards ensure reliable power delivery under any operating conditions.

10-Year Warranty Coverage

Backed by Antec's 10-year warranty, the HCG850 PRO Platinum demonstrates the manufacturer's commitment to quality and long-term reliability.
