1300 W ATX 3.1 power supply

The ASRock PG-1300G delivers 1300 W of fully modular power certified to ATX 3.1 and PCIe 5.1 standards. It carries 80 PLUS Gold and Cybenetics Gold efficiency ratings plus a Cybenetics A noise rating. Japanese capacitors and a 135 mm striped axial FDB fan with iCool intelligent control provide reliable operation for high-performance builds.

ATX 3.1 and PCIe 5.1 compatibility check

Verify that your motherboard and graphics card support the ATX 3.1 and PCIe 5.1 specifications before ordering. The unit includes a native 12V-2x6 connector with dual-colour design and TempGuard temperature monitoring. Ensure your case has clearance for a full-modular ATX power supply and that the +5V Boost switch setting matches your component requirements.

Full modular cabling for high-wattage builds

The fully modular cable set lets you connect only the leads your build needs, reducing clutter and improving airflow. The 12V-2x6 connector supports up to 220 % power excursion for modern GPUs, while the +5V Boost mode regulates the rail to approximately 5.15 V when enabled. iCool mode keeps the fan off at low to medium loads, freeing up acoustic headroom for other components.
