GaN MOSFET Technology for Superior Efficiency

The ROG Strix Platinum PSU features innovative GaN MOSFET technology that delivers up to 30% better power efficiency compared to traditional silicon designs. This advanced component generates less heat and operates more efficiently, reducing energy waste and keeping your electricity bills lower. The compact size of GaN MOSFET also allows for a more organised internal layout, creating space for larger heatsinks and improved airflow for enhanced thermal performance.

Intelligent Voltage Stabilisation for GPU Protection

Equipped with an Intelligent Voltage Stabilizer, this PSU ensures your graphics card receives steady, clean power even during intense gaming sessions or heavy workloads. This is particularly crucial for modern GPUs that demand consistent voltage to maintain peak performance and prevent instability. The technology actively monitors and adjusts power delivery to protect your expensive components from voltage fluctuations that could cause crashes or hardware damage.

ATX 3.1 Compliance and PCIe 5.0 Ready

Future-proof your build with ATX 3.1 compliance and native 12V-2×6 connector support. This PSU is engineered to handle the latest hardware requirements, including the power-hungry demands of next-generation graphics cards and processors. The 850W capacity provides ample headroom for high-end gaming systems with multiple GPUs, extensive cooling solutions, and RGB lighting setups, ensuring your rig can handle current and upcoming hardware without power limitations.

ROG Heatsinks for Extended Component Lifespan

ROG heatsinks facilitate lower operating temperatures throughout the PSU, directly contributing to longer component lifespan and extended 0dB operation during light loads. The enhanced cooling design means the fan stays off during low-power usage, creating a completely silent computing experience when browsing or performing light tasks. Under heavy loads, the optimised heatsink design maintains efficient heat dissipation, preventing thermal throttling and ensuring consistent performance during marathon gaming sessions.
