The Seasonic VERTEX PX-750 is a 750-watt power supply unit designed for systems that require stable and efficient power delivery. It meets the 80 PLUS Platinum certification standard, operating with high efficiency to minimize wasted heat and energy consumption. Full compatibility with ATX 3.1 and PCIe 5.1 standards ensures it can properly power modern components, including high-demand graphics cards. The fully modular design allows for the use of only necessary cables, which simplifies installation and improves airflow within the chassis.
This unit's thermal management is handled by a 135mm Fluid Dynamic Bearing (FDB) fan, chosen for its quiet acoustic profile and operational longevity. A digital hybrid fan control feature allows the PSU to operate in a fanless mode under low to medium loads, reducing noise levels to a minimum. The power supply is built with a comprehensive suite of protection circuits, including Over Power, Over Voltage, and Short Circuit Protection, to safeguard connected hardware. Its standard ATX dimensions ensure a straightforward fit in most mid-tower and full-tower cases.
