Antec HCG1000 PRO Platinum ATX 3.1 Fully Modular Smps

The Antec HCG1000 PRO Platinum is a 1000-watt fully modular power supply built for high-performance gaming rigs and enthusiast workstations. Certified to the ATX 3.1 standard and compatible with PCIe 5.1, it pairs natively with the latest generation discrete graphics cards via the included 12VHPWR GPU cable, eliminating the need for adapter chains and reducing the risk of connector-related power events. At the heart of the HCG1000 PRO is Antec's PhaseWave Design, a server-grade full-bridge LLC topology with synchronous rectification on a DC-DC conversion stage. This architecture delivers tight voltage regulation and minimal ripple and noise across all rails, translating to stable, consistent power under sustained and transient loads alike. All internal filtering is handled by 100% Japanese-sourced electrolytic capacitors, a choice associated with long-term reliability and low equivalent-series-resistance characteristics. The 80 PLUS Platinum efficiency certification means the unit operates at high conversion efficiency across its rated load range, generating less waste heat and lowering electricity consumption compared to Gold-rated or unrated alternatives. Thermal management is handled by a 135mm fluid-dynamic-bearing (FDB) fan. The Zero RPM Manager holds the fan at standstill during light and moderate loads, producing no audible fan noise until thermal demand requires active cooling—extending fan lifespan in the process. Full modularity means only the cables you actually need are installed inside the case. This simplifies builds, improves internal airflow by removing cable clutter, and makes future upgrades or re-cables straightforward. A comprehensive CircuitShield protection suite guards the system and connected components against over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-power (OPP), over-temperature (OTP), surge (SIP), and no-load (NLO) fault conditions.
