The Seasonic Vertex GX-750 is an ATX power supply unit that provides 750 watts of continuous power. It operates with 80 PLUS Gold certified efficiency, which minimizes heat generation and energy consumption. This model is built to ATX 3.0 and PCIe 5.1 standards, providing native support for modern high-performance components through its included 12V-2x6 connector. The fully modular cabling system permits the use of only required cables, which can improve internal airflow and simplify the build process.

For thermal management, the unit utilizes a 135 mm Fluid Dynamic Bearing (FDB) fan, selected for its operational lifespan and low noise profile. A Hybrid Silent Fan Control feature enables a semi-passive mode, deactivating the fan under low to moderate loads to reduce audible noise. The PSU is housed in a standard ATX enclosure with a depth of 160 mm. A comprehensive suite of protection circuits, including over voltage (OVP) and over power (OPP), is integrated to safeguard connected hardware.
