Product information

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

How to use

Install the Seasonic VERTEX PX-750 into a compatible ATX case, secure it with screws, and connect the 24-pin ATX cable to the motherboard. Attach the PCIe 16-pin (12VHPWR) connector to supported graphics cards when required, and use the provided SATA and peripheral cables for drives and accessories.
