750 W ATX 3.1 power supply

This fully modular unit delivers 750 W of continuous power and meets the ATX 3.1 and PCIe 5.1 specifications. It is built for modern gaming systems that need a native 12V-2x6 connection for high-end graphics cards. The compact 150 mm by 150 mm footprint helps with cable routing and airflow.

80 PLUS Gold efficiency and excursion limits

The 80 PLUS Gold certification confirms up to 90 percent efficiency at typical loads, reducing waste heat and fan speed. ATX 3.1 compliance means the PSU can handle 220 percent total power excursions and 3x GPU power excursions without tripping protections. A Cybenetics A noise rating reflects very low acoustic output.

Native 12V-2x6 connector rated for 300 W

The included dual-color 12V-2x6 cable supports up to 300 W directly to a PCIe 5.1 graphics card, removing the need for adapters. A yellow connector housing lets you verify full insertion at a glance. This single specification decides whether the unit matches your GPU power requirements.

Questions about this item

Should I choose the 750 W unit or look for a higher-wattage model?

The 750 W rating is the continuous maximum this PSU can deliver; if your GPU and CPU combined draw less than that under load, this unit will run them without needing extra headroom.

What does the 80 PLUS Gold rating mean once the PSU is installed in my PC?

It guarantees at least 90 percent efficiency at typical loads, so less electricity is wasted as heat and your components run cooler and quieter.

How much power can the native 12V-2x6 connector actually supply to a PCIe 5.1 graphics card?

The connector is rated for up to 300 W, matching the PCIe 5.1 specification for a single high-end GPU.
