Product Features
Built for modern high-performance systems, ATX 3.1 compliance helps you power demanding components with confidence. Support for the 12V-2x6 connector makes it easier to match the needs of newer hardware without feeling like your PSU is the limiting factor. In heavy workloads like gaming, rendering, or data processing, the design focus stays on stability so your system can keep running smoothly.

With 80 Plus Gold certification, efficiency stays strong even when your PC is working hard. Hitting up to 91.40% (115V) efficiency at 50% load helps reduce wasted power, which can also mean less heat to deal with inside the case. That makes it a practical choice for mid-to-high level components, including the latest CPUs and GPUs.
Quiet operation comes from an intelligent fan-curve design that starts the fan at a low RPM and scales as needed. This approach keeps noise down during everyday use while still providing cooling when the load ramps up. By improving and extending fan performance, it also supports a longer PSU lifespan over time.
Long-term reliability is reinforced with premium all 105C Japanese capacitors designed for stability. During intense sessions, support for up to 235% power excursion helps the system handle sudden power spikes and avoid crashes. Fully modular cabling keeps the build cleaner and makes cable management easier, especially in workstation or server-style setups.
