Frequently Asked Questions - TUFGaming750B ASUS

How to install the TUF GAMING 750B power supply?

First, secure the power supply unit in the chassis using the provided screws. Then connect the cables: the main 24-pin connector to the motherboard, the 4+4-pin CPU connector to the processor power socket, the 6+2-pin PCIe connectors to the graphics card, and the SATA cables to the peripherals. Finally, plug in the AC power cord and flip the switch to 'I'.

What cables are included with the power supply?

The power supply comes with a main 24-pin (or 20-pin) power cable, a 4+4-pin CPU cable, a 6+2-pin PCIe cable, SATA cables, a 4-pin peripheral cable, and the AC power cord.

Can I use modular cables from another power supply?

No, you must only use the cables provided with this power supply. Using cables from other brands or models may damage components and void the warranty.

What should I do if the power supply fan does not spin?

Check that the switch is set to 'I' and the power cord is plugged in. If the power supply is under low load, the fan may not spin (semi-passive function). If the problem persists, contact ASUS support.

Is it dangerous to open the power supply?

Yes, extremely dangerous. Never open the case as high internal voltages persist even after unplugging. No internal components are user-serviceable.

What is the maximum operating temperature?

The recommended operating temperature is 0°C to 40°C. Relative humidity should be between 5% and 95%.

Is the power supply compatible with my motherboard?

Yes, it is compatible with any motherboard with a 24-pin ATX connector and a 4+4-pin CPU connector. Check your graphics card requirements for the number of PCIe connectors.

What should I do if the power supply overheats?

Ensure that ventilation is not blocked and that the power supply is in a room temperature environment (<40°C). If the power supply shuts down automatically, let it cool before restarting.

The power supply is making noise. Is that normal?

A slight fan noise is normal. If the noise is abnormal (grinding, clicking), check that no cable is obstructing the fan. If the noise persists, contact customer service.

How to clean the power supply?

Unplug the power supply and clean the exterior with a soft, dry cloth. Do not use liquid and do not insert any objects into the openings. Never clean the inside.
