Product Description
ASUS ROG Strix 850W 80+ Platinum ATX 3.1 Fully Modular PSU

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.
Optimised for Power and Speed
Elevate your build with the ROG Strix 850W Platinum, engineered for elite gamers and creators. Featuring GaN MOSFETs for superior power efficiency, intelligent voltage stabilization for your GPU, and 80 PLUS Platinum certification, this PSU ensures unwavering performance and quiet operation under load. With ATX 3.1 compliance and PCIe 5.0 support via a native 12V-2×6 cable, it’s built to power the latest RTX 40-series graphics cards and future-proof your rig.

2x longer lifespan
Dual Ball Fan Bearings
Dual ball bearings boast a remarkable lifespan of 80,000 hours, lasting twice as long as sleeve bearings and exceeding even fluid dynamic bearings.
Ensuring long-lasting, reliable cooling with minimal noise for ROG STRIX Platinum series.
