ATX 3.1 & PCIe 5.1 Ready for Next-Gen GPUs

The HCG1000 PRO supports the latest ATX 3.1 specification and includes a PCIe 5.1 12VHPWR cable, ensuring seamless compatibility with NVIDIA RTX 40 Series graphics cards. This PSU handles high power transients and delivers stable power delivery under heavy GPU loads, making it ideal for cutting-edge gaming and content creation systems.

PhaseWave Design for Rock-Solid Stability

Antec’s PhaseWave™ design uses a server-class full-bridge LLC topology with synchronous rectification, delivering ultra-low ripple and noise. This ensures consistent voltage regulation even under peak loads, protecting your components and maintaining system stability during intensive tasks.

Whisper-Quiet Cooling with Zero RPM Mode

The 135mm fluid-dynamic bearing fan operates silently under low to medium loads thanks to the Zero RPM Manager. Thermal sensors activate the fan only when needed, balancing quiet operation with efficient cooling. This extends fan life and keeps your build noise-free during everyday use.

Industrial-Grade Protection with CircuitShield

The CircuitShield™ suite includes OCP, OVP, UVP, SCP, OPP, OTP, SIP, and NLO protections. These safeguards protect your valuable components from electrical faults, ensuring safe and reliable power delivery in any situation.

Compact Size, Full Modular Flexibility

Despite its high power output, the HCG1000 PRO features a compact ATX form factor that fits a wide range of PC cases. Its fully modular cabling system reduces clutter, improves airflow, and allows for clean, custom cable routing tailored to your build.
