Product information

Description

The Seasonic PRIME PX 3.0 Series 1600 W power supply provides ATX 3.0 and PCIe 5.0 (12VHPWR) compatibility, native 12VHPWR connectors, Digital Hybrid Fan Control and 105°C-rated Japanese electrolytic capacitors for stable long-term operation. The unit targets high-performance systems and is suitable for modern high-power graphics cards and processors while achieving 80 PLUS® Platinum efficiency.

Advantages

The PRIME PX 3.0 offers high conversion efficiency (80 PLUS® Platinum), tight voltage regulation with under 0.5% load variation, and a Digital Hybrid Fan Control system that minimizes fan noise. It uses Fluid Dynamic Bearing (FDB) fans for reduced noise, lower vibration and extended lifespan. A cable-free connection design between the back panel and PCB improves output quality and reduces assembly error risk.

Key specifications

  • Rated power: 1600 W
  • Efficiency: 80 PLUS® Platinum (≈92% at 50% load)
  • ATX standard: ATX 3.0 compatible
  • PCIe connector: Native 16‑pin PCIe Gen5 (12VHPWR)
  • Capacitors: 105°C Japanese electrolytic capacitors
  • Fan: Fluid Dynamic Bearing (FDB) with Digital Hybrid Fan Control
  • Load regulation: Micro tolerance, under 0.5% load variation
  • Connection design: Copper-plate cable-free back panel to PCB connection

How to use

Install the power supply into a compatible ATX 3.0 chassis following the motherboard and case manufacturer instructions. Connect the native 16-pin PCIe (12VHPWR) cable directly to supported graphics cards and use the provided modular cables for other system components. Ensure adequate airflow in the case to allow the Digital Hybrid Fan Control to operate effectively. Observe standard safety practices: disconnect mains power before installation, route cables to avoid contact with fans, and verify all connectors are fully seated before powering on.

Recommendations

Use this 1600 W Seasonic PRIME PX 3.0 unit with modern high-power GPUs and CPUs that require ATX 3.0 / PCIe Gen5 power. Maintain case airflow, periodically inspect connections and replace filters to preserve fan performance and cooling efficiency.
