Key Specifications

ATX 3.1 & PCIe 5.1 Compliance

This PSU is fully compliant with ATX 3.1 and PCIe 5.1. It supports the native 12V-2×6 connector for next-gen graphics cards. The unit can handle transient power spikes up to 220% of its rated capacity. This ensures your high-end GPU receives stable power during intense gaming sessions. It is ready for future hardware releases.

Silent Cooling with iCOOL Mode

The unit features a 135mm Fluid Dynamic Bearing fan. This design minimises noise and maximises lifespan. You can toggle the iCOOL mode via a physical switch. When enabled, the fan remains off during low to medium loads. This creates near-silent operation for UK home offices or media centres. The fan only spins up when temperatures rise.

Voltage Stability & Protection

The PG-750G includes a +5V Boost Mode switch. This compensates for voltage drop, regulating the rail to approx. +5.15V. It ensures consistent power for your peripherals and motherboard. The unit also features Cable Over-Temperature Protection. An NTC sensor monitors the VGA connector temperature. It signals the PSU to maintain safe operation under load.

Component Quality & Efficiency

ASRock uses industrial-leading Infineon CoolMOS and 105°C Japanese capacitors. These components guarantee high efficiency and long-term reliability. The PSU holds 80 PLUS Gold and Cybenetics Platinum certifications. It also earns a Cybenetics Lambda A+ acoustic rating. This confirms superior energy efficiency and ultra-quiet operation for your build.

Comprehensive Safety Suite

Safety is a priority with full protection circuits built-in. The unit includes OCP, SCP, OVP, UVP, OTP, and OPP. These safeguards protect your components from power anomalies. The dual-colour design on connectors offers visual confirmation of a secure fit. This reduces installation errors during your build process.
