AI Verdict

This 850-watt 80+ Platinum ATX power supply with an OLED power display and Aura Sync is for builders prioritizing aesthetics and quiet operation in high-end systems.

Strong Fit

This 850W 80+ Platinum power supply is a strong fit for high-performance gaming systems, especially those with modern GPUs requiring PCIe 5.0 power. Its Lambda A++ certification and 0dB mode ensure quiet operation, while the OLED display and Aura Sync cater to aesthetic preferences.

If 850 watts isn't enough for your extreme build, look for models with Titanium efficiency certification and higher wattage, like the ROG Thor III 1000W or 1200W.

What Buyers Say

Users frequently highlight the aesthetic appeal of the ROG Thor 850W Platinum II, particularly the integrated OLED display that shows real-time power consumption, which many find a cool and useful feature. The quiet operation, especially the 0dB mode, is a recurring point of praise, contributing to a less distracting computing environment. While the price is sometimes mentioned as a consideration, the overall sentiment points to satisfaction with the build quality and premium features. The inclusion of ATX 3.0 and PCIe 5.0 compatibility with the 12VHPWR connector is also appreciated for future-proofing high-end builds.

“Man, this thing looks insane in my build, the little screen is actually useful for once, and I can't even hear it running most of the time. Worth the extra cash if you care about looks and quiet.”

Common Praise

  • The OLED display accurately shows real-time power draw.
  • Operates silently under low to moderate loads due to the 0dB fan mode.
  • Cables are fully modular and mostly sleeved, making installation clean.
  • The build quality feels premium with durable components.
  • Aura Sync compatibility integrates well with other RGB components.

Common Complaints

  • The price point is higher than many comparable wattage PSUs without the aesthetic features.
  • SATA and Molex cables are flat and not sleeved, which can detract from a fully customized look.
  • The top grill can impede airflow, requiring removal for optimal cooling.

Ownership Tips

  • The OLED display remains readable even in a dark case.
  • The 0dB fan mode really does keep the system silent during light tasks.
  • The sleeved cables are stiff initially but hold their shape well once routed.
  • Aura Sync integration works seamlessly with other ASUS components.
