Since its 2016 debut, the Seasonic PRIME flagship series has set the benchmark for high-reliability power delivery in demanding PC builds. Engineered with premium components and cutting-edge technology, PRIME ensures consistent, stable output for professional and enthusiast applications.

The PRIME TX-1600 stands as the series’ pinnacle, embodying Sea Sonic’s R&D expertise. Its ultra-low-loss analog circuit architecture delivers Titanium-grade efficiency—even at full 1600W load—with conversion rates exceeding 95%, earning it the groundbreaking CQC Level 5 certification (the highest for retail-grade PSUs from China’s Quality Certification Center). It features tight voltage regulation (<0.5% deviation), superior ripple suppression, and robust handling of dynamic loads, surpassing ATX 3.0 (and supporting newer standards in updated variants) requirements.

The series includes SDP (Smart Dual Protection) for reliable performance under heavy, sustained loads. Backed by an industry-leading 12-year warranty, PRIME TX-1600 reflects Sea Sonic’s commitment to long-term durability and exceptional support.

Leading the Industry’s Energy Efficiency Evolution
First Retail PSU to Achieve CQC Level 5 Certification

The Seasonic PRIME TX-1600 sets a groundbreaking milestone as the first retail PC power supply to earn CQC Level 5 energy efficiency certification from the China Quality Certification Center—the highest level attainable for consumer/retail embedded power supplies in the seven-tier system (Level 1–7).

Surpassing its dual Titanium certifications from both the 80 PLUS organization and Cybenetics, the PRIME TX-1600 delivers ultra-high conversion efficiency exceeding 95%, even under demanding loads. This achievement highlights the series’ superior engineering in efficiency, consistent performance, and long-term reliability.

CQC Level 5 goes beyond peak efficiency metrics: it rigorously evaluates product consistency, key component reliability, and comprehensive audits of R&D, manufacturing, testing, and production processes—ensuring top-tier quality and supporting sustainable industry growth.

This landmark reinforces the PRIME TX-1600 as the ultimate choice for high-performance systems demanding unmatched efficiency and stability.

Driven by Rigorous Technical Ambition in Power Supply Engineering

Seasonic PRIME TX-1600: Built on Three Core Pillars of Engineering Excellence

The PRIME TX-1600 is built around several key engineering principles that support its efficiency and stability targets.

1. Optimized Power Architecture
   Advanced Circuit Architecture Features a bridgeless interleaved PFC with full-bridge LLC and synchronous rectification, drastically reducing energy losses at the source for superior efficiency and performance.
2. Premium Tier-One Components
   Sourced from global leaders like Infineon and Texas Instruments for power and control ICs, paired with high-quality 105°C-rated Japanese electrolytic and solid capacitors. This ensures precise, stable output under extreme conditions and heavy dynamic loads—underpinning the 12-year warranty and exceptional long-term durability.
3. High-Efficiency Thermal Design with SDP Smart Dual Protection
   Combines optimized power architecture and advanced thermal management for sustained high-wattage output with controlled temperatures. SDP (Smart Dual Protection) delivers multi-layered safety through hardware rapid-response and firmware precision control, guaranteeing stability, protection, and reliability even under prolonged heavy loads.

The PRIME TX-1600 embodies Sea Sonic’s relentless pursuit of perfection for uncompromising high-performance systems.

In professional workstations and AI-intensive systems with long runtimes and frequent load fluctuations, reliable power delivery is critical.

The Seasonic PRIME TX-1600 achieves this through meticulous power architecture and premium component selection, delivering consistent, predictable output under any condition, fully meeting the strict stability demands of professional-grade computing.

At the same time, its groundbreaking CQC Level 5 energy efficiency certification marks a major milestone in Sea Sonic’s pursuit of ultra-high efficiency in high-power designs.
