ASUS ROG Thor 850W Platinum II Power Supply - Quiet, OLED Monitoring

Our review of the ROG Thor 850W Platinum II finds it aimed squarely at PC builders who want high-end, visually coordinated power and precise monitoring. The single biggest reason to consider this unit is its real-time OLED display paired with robust cooling and premium internals, which together give a reassuring combination of performance visibility and long-term reliability for demanding gaming or workstation builds. This review looks at cooling, noise, build quality and real-world usability so you can decide if the Thor fits your system.

Key Features

• Lambda A++ Certification: Confirms the unit delivers high efficiency and very low losses under typical loads for cooler operation and lower energy costs.
• ROG heatsinks: Cover critical components to reduce temperatures and help keep fan noise down during sustained loads.
• 135mm PWM fan with 0dB mode: Balances cooling and silence by running quietly at common loads and stopping fan spin when thermal headroom allows.
• 100% Japanese capacitors and 80 Plus Platinum: Use of premium components improves longevity and stable power delivery for high-performance GPUs and CPUs.
• OLED panel: Shows power draw in real time so builders can monitor consumption without extra software.
• Aura Sync compatibility: Lets users sync lighting with other compatible components for a unified build aesthetic.

Who It's For

The ROG Thor 850W Platinum II is best for enthusiasts building high-end gaming PCs or compact workstations that need a reliable, fully modular power supply with advanced monitoring and a focus on quiet operation. The OLED and Aura Sync features also appeal to builders who value visible system telemetry and coordinated lighting.

Users who want a simple, budget entry-level power supply or who do not care about modular cables, visual monitoring, or premium cooling can look elsewhere to save cost. Those who require extreme wattage beyond the unit's rating should select a higher-capacity option.
