The ASRock Phantom Gaming 750W power supply is built for current and next-generation PC standards, fully compliant with ATX12V V3.1 and PCIe Gen 5.1. It supports high power excursion handling up to 220% and rapid response to power spikes, providing stable and safe power delivery for gaming and high-performance components. The unit includes a dual-color connector design for easy visual confirmation of proper connections and a cable over-temperature protection sensor at the VGA connector.

Advantages

This power supply offers 80 PLUS Gold efficiency with Cybenetics Platinum & Gold ratings and LAMBDA A acoustic certification for low-noise operation. It uses a 135 mm fluid dynamic bearing fan with a herringbone structure for long life and quiet operation. Industrial-grade Infineon CoolMOS components and 105 °C Japanese capacitors ensure high reliability and extended lifespan. Additional features include a +5V BOOST mode for voltage compensation, iCOOL intelligent fan control with selectable modes, and a full suite of safety protections. ASRock provides a 10-year warranty for long-term support.

How to use

Install the PSU in a compatible ATX chassis and connect the 20+4 pin ATX cable to the motherboard and other modular or fixed connectors to your components following the motherboard and GPU manufacturer guidelines. Use the ASRock Classic Green connector indicator to confirm each plug is fully seated. If required, enable the +5V BOOST switch to compensate for voltage drop; when enabled the +5V rail will be regulated near +5.15V under normal conditions. Select iCOOL Mode ON for quieter operation at low to medium loads or iCOOL Mode OFF for continuous fan operation during sustained heavy loads. Ensure adequate case ventilation and monitor temperatures; the NTC sensor will signal the PSU to protect cables if over-temperature is detected.

Recommendations

For optimal reliability, pair this PSU with components that conform to ATX 3.1 and PCIe 5.1 standards, maintain good case airflow, and follow the 10-year warranty registration or service instructions provided by ASRock.
