Montech Century II Power Supply – ATX v3.1 & PCIe 5.1 Ready, Fully Modular, 80+ Gold Efficiency

ATX v3.1 & PCIe 5.1 Ready
The Montech Century II Series is built to meet the latest ATX 3.1 and PCIe 5.1 standards, ensuring full compatibility with next-generation GPUs and high-performance CPUs. With native 12VHPWR support, it can deliver up to 600W directly to GPUs such as the RTX 5000-series — no adapters required. This future-proof design guarantees smooth power delivery for modern and upcoming builds.

80+ Gold Certified Efficiency
Engineered for reliability and energy savings, the Century II offers 80 Plus Gold certification, achieving up to 90 % efficiency under typical loads. This means cooler operation, lower electricity costs, and less heat buildup inside your system, all while maintaining rock-solid stability for critical components.

Fully Modular Design
Every cable is detachable, allowing you to use only what’s needed for your specific build. This simplifies cable management, improves airflow, and gives your setup a clean professional look — ideal for high-end gaming or workstation PCs.

Smart Zero-Fan Cooling
The intelligent zero-RPM mode keeps the fan completely silent during low loads. When temperatures rise, the 120 mm fluid-dynamic bearing fan automatically activates to deliver quiet and efficient cooling. This smart design reduces noise, extends fan life, and keeps your system running at optimal temperatures.

Stable & Durable Build Quality
Built with 100 % Japanese capacitors, the Century II ensures excellent voltage regulation, ripple suppression, and long-term durability. The internal layout prioritizes thermal efficiency and electrical stability, providing consistent performance even under heavy loads. Montech’s signature industrial-grade protections (OCP, OVP, SCP, OPP, UVP) safeguard every component against power fluctuations or short circuits.
