ATX 3.1 power supply for modern GPUs

The Seasonic FOCUS GX-750 is a fully modular ATX 3.1 power supply rated at 750 W. It targets builders assembling systems around current-generation graphics cards that require the updated power standard.

750 W maximum power rating

The single specification that determines compatibility is the 750 W maximum output. This figure must meet or exceed the combined load of every component in the build, especially the graphics card and CPU under full load.

135 mm FDB fan and Gold efficiency

A 135 mm fluid dynamic bearing fan handles cooling while the 80 PLUS Gold certification ensures high efficiency across typical loads. The unit operates on 100 to 240 V input at 50 or 60 Hz for worldwide compatibility.
