## Long description

The Seasonic VERTEX PX-750 is a 750 W ATX power supply designed for modern PC builds that require ATX 3.0 and PCIe Gen5 (12VHPWR) compatibility. It delivers high energy efficiency with 80 PLUS Platinum certification and integrates a 135 mm fluid dynamic bearing fan and hybrid fan control for quiet, reliable cooling.
Advantages
The unit provides up to 750 W of continuous power and maintains around 92% efficiency at 50% load thanks to its 80 PLUS Platinum rating. Native support for ATX 3.0 and the 16-pin PCIe Gen5 (12VHPWR) connector ensures compatibility with current high-end GPUs and platforms. The premium hybrid fan control minimizes audible noise by stopping or slowing the fan under low loads, while the fluid dynamic bearing fan reduces friction and vibration for longer life and lower operating noise.
Suitable for
Gaming desktop builds with high-performance GPUs
Workstations requiring stable 750 W power delivery
PCs that demand ATX 3.0 and PCIe Gen5 (12VHPWR) compatibility
Quiet or acoustics-focused systems
