Extended Product Information

FAQs

Is this power supply compatible with older motherboards?

Yes, it uses the standard 20+4 pin ATX connector, which is backward compatible with virtually all standard motherboards.

Does it include cables for all my components?

Yes, the package includes CPU, PCIe (including 16-pin), SATA, and Molex cables to support most common PC configurations.

Can I use this for a 24/7 workstation?

Absolutely. With a 120,000-hour MTBF and dual-ball bearing fan, it is designed for high-reliability, long-term operation.

What does the 'Fully Modular' feature mean?

It means every cable can be detached from the power supply, allowing you to only install the cables necessary for your specific build, reducing clutter.

What does the 80 PLUS Gold certification indicate?

It signifies that the power supply is at least 87-90% efficient at various load levels, which translates to less power wasted as heat.

Troubleshooting

System will not power on

Ensure the rear I/O switch is set to the 'I' position and verify that the AC power cable is firmly seated in both the wall outlet and the PSU.

Unexpected system shutdowns

This may be an activation of power protection (OPP/OCP). Ensure your total component power draw does not exceed 750W and check that all power cables are securely connected to the motherboard and GPU.

Excessive fan noise

Check if any loose cables are interfering with the fan blades. If the noise persists, ensure the PSU has enough clearance from the bottom of the case to pull in fresh air.

Pros and Cons

Pros

  • ATX 3.1 and PCIe 5.1 compliance ensures compatibility with latest-gen GPUs
  • Highly efficient 80 PLUS Gold certified power delivery
  • Durable 135mm dual-ball bearing fan for long-term cooling reliability
  • Fully modular cabling makes installation and cable management seamless
  • Comprehensive built-in power protection circuitry

Cons

  • 750W limit may not be sufficient for extreme high-end multi-GPU workstations
  • Standard ATX size may be tight in some ultra-compact Small Form Factor (SFF) cases
  • Non-custom cables may still be stiff for very small builds

Setup, Compatibility & Care

Installation of the ASUS Prime 750W Gold is straightforward due to its fully modular interface. Follow these guidelines for optimal use:

  1. Placement: Ensure the fan faces the vent on your PC case (usually downward if your case has an intake filter).
  2. Cable Routing: Connect the 24-pin motherboard and 8-pin CPU power cables first, then use the provided etched cables for your storage and GPU, connecting them to the modular ports on the back of the PSU before mounting it in the chassis.
  3. Compatibility: Verify your motherboard has a 20+4 pin ATX slot and your case supports standard ATX power supplies (150mm x 86mm x 150mm).
  4. Maintenance: Periodically check your intake dust filters to ensure the PSU fan has unrestricted access to clean air. Avoid using compressed air directly into the fan housing to prevent bearing damage; instead, use a soft brush to clean dust off the fan blades.
