Frequently Asked Questions - ROG Thor 850W Platinum II ASUS

How to install the ROG Thor 850W Platinum II power supply?

Before installation, turn off the computer and unplug all cables. Secure the power supply in the chassis using the provided screws. Connect the modular cables as needed (motherboard, CPU, GPU, etc.). Plug in the AC power cord, then switch the power switch to the I position.

What does the 0 dB fan mode mean?

The 0 dB button allows the fan to stop completely when the load is low. Thus, the power supply operates silently as long as the power consumption remains moderate.

Can I use cables from another brand with this power supply?

No, use only the modular cables provided with the ROG Thor. Third-party cables may have different pinouts and damage components.

How to clean the power supply?

Unplug the power supply and wait a few minutes. Use a dry cloth or compressed air can to remove dust from the grille and fan. Never open the casing.

What is the recommended power for my setup?

The ROG Thor 850W Platinum II is suitable for most high-end gaming setups with a graphics card like RTX 3080/4080 or equivalent. Check the total power consumption of your components to stay under 850W.

What to do if the OLED display does not turn on?

Make sure the power supply is powered on and the signal connector is properly connected. If the issue persists, contact ASUS support. The OLED displays real-time power consumption.

Is the power supply compatible with ATX and micro-ATX motherboards?

Yes, it is compatible with all standard form factors thanks to its 24-pin ATX connector. Adjust the mounting according to your chassis.

What are the built-in protections?
