03PERFORMANCE

Stable voltage under load

With tight voltage regulation holding 12 V, 5 V and 3.3 V rails within ±3%, the unit provides consistent power to sensitive components. The 12 V rail delivers up to 996 W, supporting demanding processors and graphics cards during peak usage.

04COOLING

Quiet operation via large fan

A single 135 mm fan uses a fluid dynamic bearing rated for 50,000 hours at 40 °C. Digital fan control adjusts speed based on load, keeping noise levels low during idle states while maintaining airflow when the system works hard.

05CONNECTIVITY

Modern standards for GPUs

The included 16-pin PCIe Gen 5 cable connects directly to newer graphics cards, eliminating the need for adapters. Fully modular connectors let builders attach only the cables they require, reducing clutter inside the case.

06RELIABILITY

Built for long-term service

Gold-plated terminals handle high current flow for motherboard, CPU and PCIe connections. With an MTBF of 100,000 hours excluding the fan and comprehensive protections like OVP and OCP, the unit is designed to last through multiple hardware generations.
