Overview

A fully modular 1600W ATX 3.1 power supply with 80 PLUS Platinum efficiency, native 12VHPWR connectors, and a 12-year warranty. Built for high-end GPUs and CPUs.

Platform and Standards

The Prime PX 3.0 series meets ATX 3.1 and PCIe 5.0 specifications. It delivers 1600W through a single +12V rail with load regulation under 0.5 percent. Japanese 105°C electrolytic capacitors support long-term reliability.

Cooling and Acoustics

A 135mm Fluid Dynamic Bearing fan runs in hybrid semi-passive mode, staying off at low loads. Digital Hybrid Fan Control adjusts the curve dynamically to minimize noise while maintaining safe temperatures.

Connector Layout

Two native 12VHPWR connectors supply power for modern graphics cards. Six 6+2-pin PCIe, three 4+4-pin EPS, eighteen SATA, and three 4-pin Molex connectors cover all other components.

Internal Architecture

A copper plate replaces traditional cables between the back panel and main PCB, reducing insertion errors and improving output quality. The fully modular design keeps cable clutter to a minimum.
