ANTEC HCG1000 Pro 1000W 80+ Platinum Fully Modular ATX 3.1 Power Supply ( 1000W )

The Antec HCG1000 Pro is a 1000W fully modular power supply built to the ATX 12V 3.1 standard, targeting high-end gaming rigs and enthusiast workstations that demand clean, stable power delivery. Certified 80 PLUS Platinum, it achieves high efficiency across its operating load range, reducing wasted heat and helping keep your system cool during extended sessions. At the heart of the HCG1000 Pro is Antec's PhaseWave Design — a server-class full-bridge LLC topology with synchronous rectification and a DC-DC conversion stage. This architecture produces tight voltage regulation with minimal ripple and noise, thanks in part to 100% Japanese electrolytic capacitors throughout the power path. The included PCIe 5.1 12VHPWR connector (16-pin, 12+4) provides native compatibility with current-generation discrete graphics cards including NVIDIA GeForce RTX 40-series, while three additional 8-pin (6+2) PCIe connectors support multi-GPU or legacy configurations. The full connector set includes one 24-pin ATX motherboard cable, two 8-pin (4+4) CPU cables, 14 SATA connectors, and three Molex connectors — providing ample connectivity for complex builds without unnecessary cable clutter. Thermal management is handled by a 135mm fluid-dynamic bearing (FDB) fan operating under the Zero RPM Manager system, which keeps the fan fully stopped under light loads for silent operation and only spins up when temperatures require active cooling. This approach extends fan lifespan while keeping acoustics low during everyday workloads. The HCG1000 Pro's CircuitShield protection suite provides eight distinct safeguards: over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-power (OPP), over-temperature (OTP), surge and inrush protection (SIP), and no-load operation (NLO).
