FAQs

What is ATX 3.1 and why is it important?

ATX 3.1 is an updated standard for power supply units, designed to better handle the power demands and transient spikes of modern, high-power components, especially next-generation graphics cards. It ensures greater stability and compatibility.

What does 80 PLUS Gold certification mean?

80 PLUS Gold certification indicates that the PSU is highly energy-efficient, converting AC power to DC power with at least 87-92% efficiency at various load levels. This reduces wasted energy, lowers heat output, and decreases electricity consumption.

What is a fully modular PSU?

A fully modular PSU means all cables are detachable. This allows you to connect only the cables you need for your specific build, resulting in a cleaner interior, better airflow, and easier installation.

What is the advantage of a dual-ball bearing fan?

Dual-ball bearings reduce friction and wear, making the fan more durable and longer-lasting compared to traditional sleeve bearings. They also perform well under various orientations.

Can I use the 16-pin PCIe 5.1 cable with older graphics cards?

While the 16-pin connector is designed for PCIe 5.1, it may not be compatible with older graphics cards that use different power connectors. Always check your graphics card's power input requirements.

How do I clean the power supply fan?

To clean the fan, ensure the PC is powered off and unplugged. Use a can of compressed air to blow dust away from the fan and PSU vents. Do not attempt to open the PSU casing.

What is the warranty period for this PSU?

ASUS typically offers an 8-year warranty on their Prime Gold series PSUs, but it's recommended to check the official ASUS product page or your purchase documentation for the exact warranty terms.

Troubleshooting

PC will not power on.

Ensure the PSU power switch is in the 'on' position and the AC power cord is securely connected to both the PSU and a working wall outlet. Double-check all internal power connections to the motherboard and components.

System is unstable or crashing under load.

Verify that all power cables are securely connected. Ensure the PSU wattage is sufficient for all components. Check for excessive dust buildup that could be causing overheating.

Fan is not spinning.

The fan may not spin under low load conditions to minimize noise. If it's not spinning under heavy load, check for obstructions and ensure the PSU is receiving adequate power. Contact support if the issue persists.

Noise from the PSU.

Slight coil whine may be present under certain load conditions, which is normal for high-performance PSUs. Persistent or loud clicking or grinding noises indicate a potential hardware issue; contact support.
