Antec HIGH CURRENT GAMER HCG1000 PRO ATX 3.1 1000W 80PLUS Platinum PSU Power Supply

A 1000W power supply with ATX 3.1 and PCIe 5.1 certification, designed for high-end gaming and workstation builds. The unit features 80 PLUS Platinum efficiency, meaning it converts approximately 90 per cent of input power with minimal energy waste. It includes a dedicated 12VHPWR GPU cable for compatibility with modern graphics cards like the RTX 40 Series, along with fully modular cabling for straightforward system building and cable management.

The supply uses a full-bridge LLC topology with Japanese capacitors for stable voltage regulation and low electrical noise. Cooling is handled by a 135mm fluid-dynamic bearing fan with a zero RPM mode that allows fanless operation under light loads. Protection circuitry covers overpower, overvoltage, undervoltage, short-circuit, and thermal scenarios. The unit comes with a ten-year warranty.
