## Long description

FOCUS GX ATX 3.0 is a high-efficiency power supply designed to meet ATX 3.0 and PCIe 5.0 standards. Available in compact 140 mm depth models from 750 W to 1000 W, the unit provides stable power delivery for modern high-performance graphics cards and processors. The supply features Seasonic's Digital Hybrid Fan Control and a Fluid Dynamic Bearing fan for balanced cooling and reduced noise.
Advantages
The power supply delivers 80 PLUS Gold efficiency and a fully modular cable design that simplifies installation and cable management.
