Seasonic PRIME SSR-1600TR2 Power Supply Noctua Edition Review

The Seasonic PRIME TX-1600 Noctua Edition is the ultimate expression of collaboration between two industry titans, Seasonic and Noctua, specifically targeting the high-end PC enthusiast and serious gamer market, as well as those with a fat wallet, as this is the final boss of enthusiast PSU design.

This power supply unit (PSU) is designed for use in the most power-hungry, flagship gaming and workstation systems, requiring an uncompromising 1600W output while simultaneously demanding near-silent operation. For those with the absolute best hardware, and even multi-GPU systems. It’s built on Seasonic’s award-winning 80 PLUS Titanium certified platform. This special edition PSU is expected to deliver class-leading performance, exceptional power efficiency, and a reduction in operational noise that sets a new benchmark for premium components thanks to its glow-up from the cooling and acoustic masters at Noctua.

The PRIME TX-1600 Noctua Edition revolves entirely around acoustic optimisation and compatibility with next-generation hardware. The core feature is the substitution of the standard fan with Noctua’s renowned NF-A12x25 120mm model, one of the absolute best PC cooling fans ever created. Coupled with a custom-designed, highly optimised fan grill to minimise turbulence and noise. This collaboration results in the unit running approximately 8–10dB(A) quieter than the already silent standard model, earning an upgraded Cybenetics Lambda A++ sound level rating. Furthermore, the PSU ensures future-proofing by natively supporting the latest ATX 3.1 and PCIe 5.1 standards, including two dedicated 12V-2×6 connectors for safely powering modern, high-TDP gaming graphics cards like the NVIDIA GeForce RTX 5090 and any of the flagship workstation GPUs used for heavy computation and AI.

Key Features

• Acoustic Performance: Cybenetics Lambda A++ certification, operating typically 8–10dB(A) quieter than the regular model.
• Cooling Fan: Features the iconic Noctua NF-A12x25 120mm fan for superior airflow and acoustic properties.
• Aero-dynamic Design: Custom-designed, acoustically optimised fan grill for reduced turbulence and lower noise emission.
• Efficiency Standard: 80 PLUS Titanium certified, achieving up to 94% efficiency at 50% system load.
• Cabling/Modularity: Fully modular cabling with an aesthetic Noctua brown and black colour scheme.
• Compliance: Fully compliant with the updated ATX 3.1 and PCIe 5.1 standards.
• Voltage Regulation: Features Micro Tolerance Load Regulation (MTLR) for ultra-tight output stability (under 0.5% load regulation).
• Fan Control: Digital Hybrid Fan Control with a semi-passive mode, allowing fully passive operation up to around 50% load.

Specifications

The technical specifications confirm this unit’s status as a top-tier enthusiast component, designed for both power and reliability. With a robust continuous total output of 1600W, delivered across a single, 12V rail rated at 133.3A, the PSU is ready to handle extreme loads from multiple high-end GPUs and CPUs simultaneously. At 210mm in length, it’s a large power supply, but still a competitive form factor given the overall power out, to ensure relatively broad case compatibility. Seasonic’s confidence in the build quality is demonstrated by a substantial 12-year manufacturer’s warranty, underlining its use of high-grade components like 105°C-rated Japanese electrolytic capacitors and comprehensive protection features including OCP, OPP, OTP, OVP, SCP, and UVP.
