- 10-year warranty included.
- 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.
- Intelligent Voltage Stabilizer - Activate the "GPU-FIRST" voltage sensing by connecting the IVS cable. This innovative feature enhances voltage stability by up to 45%, even during demanding gaming sessions and overclocking scenarios. If you prefer conventional CPU-focused voltage sensing, just simply disconnect the IVS cable. With this advanced technology, you can experience smooth and consistent gameplay.
- High-performance Copper Pins - Upgraded PCIe® connectors featuring superior thermal conductivity ensure cooler operation and improved power delivery efficiency. This translates to a significant 29% reduction in connector temperatures (up to 12.28°C), promoting optimal performance and stability for even the most demanding graphics cards.
- ATX 3.1 Compatible - ATX 3.1 ushers in tighter voltage and current regulation standard for next-gen hardware - and ROG Strix Platinum steps ahead of the curve by being fully compliant. A 16-pin PCIe cable ripe for piping up to 600W of power to PCIe Gen 5.0 graphics cards is bundled with the PSU, readying your build for the next-gen.
- 80 Plus Platinum Certification - The ROG Strix 850W Platinum utilizes low-ESR Japanese capacitors to ensure efficient operation. These upgrades enable an 80 PLUS Platinum certification, which guarantees 89% efficiency at 100% load and 92% efficiency at 50% load. The increased efficiency results in less heat, reduces fan noise, and increases reliability.
- ROG Heatsinks - ROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0dB operation.
- 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.
- 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.
- DIY-friendly CPU Power Connector - Engineered with a distinct clip between the 4+4 pin connectors and a unique color scheme, this CPU power cable simplifies cable identification during installation. The integrated clip helps to ensure a secure and effortless connection to the motherboard's CPU power connector, streamlining the build process and instilling confidence in your PC setup.
- Cosmetic Customization - Customize your own PSU with included stickers that complement the PSU's patterns. Choose your preferred color scheme for a personalized touch.
- 10-year Warranty - We're so confident about the reliability of the ROG Strix 850W Platinum that we back it with a 10-year warranty.
