The ROG Strix Platinum Series ensures your high-end rig has the power to conquer any challenge.
GaN MOSFET
The ROG Strix Platinum PSU boasts innovative GaN MOSFET that delivers superior power efficiency by up to 30%, resulting in lower energy waste. Plus, the smaller size of GaN MOSFET allows for a more organized internal layout within the PSU. This optimized design provides space for larger heatsinks and enhanced airflow, improving heat dissipation within the PSU.
ROG Heatsinks
Cool under pressure
ROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0dB operation.
Etched Cables
Made from a pliable premium material, these etched cables are easily flexible during installation, and they operate at temperatures 50°C lower than the safety limit when routed for cable management. These cables also meet the rigorous standards of the UL1581 flame test and UL758 certification, helping to ensure a smooth PC DIY experience and exceptional safety.
