High-Efficiency Power Delivery
This PSU achieves up to 93.9% efficiency at 50% load. It reduces energy waste and lowers heat output. Your system runs cooler and quieter as a result. The 80 PLUS Platinum certification validates this performance at 230V UK mains.
Future-Proof Connectivity
The unit natively supports PCIe 5.1 graphics cards via a 12V-2×6 connector. It handles power excursions up to double its rated wattage. This ensures stability with modern high-draw GPUs. You also get four PCIe 6+2-pin connectors for current-gen cards.
Silent Wings Fan Technology
It uses a 135mm Silent Wings fan with a fluid-dynamic bearing. This design produces minimal noise even under load. The funnel-shaped inlet optimises airflow while reducing turbulence. Zero RPM mode keeps the fan off during light tasks.
Premium Internal Components
The Straight Power 12 uses Japanese 105°C-rated capacitors. These components offer superior stability and longevity. Full bridge LLC topology ensures clean power delivery with low ripple. This protects sensitive hardware over time.
Modular Cable Management
All cables are fully modular and sleeved up to 100cm. This simplifies installation in large cases and reduces clutter. Improved airflow aids overall system cooling. The 12V single-rail design provides consistent power to all components.
