Seasonic is renowned as one of the leading manufacturers of premium grade PC power supplies and PRIME TX is their award-winning, 80 PLUS® Titanium certified flagship series featuring state-of-the-art electronic designs, first-class quality components, cutting-edge performance and exceptional efficiency.
The Noctua Edition of the top-end TX-1600 model uses this superb platform and combines it with the iconic, groundbreaking NF-A12x25 fan as well as a custom designed, highly optimised fan grill, which enable it to run ~8-10dB(A) quieter than the already quiet standard model. Thanks to its semi-passive fan control setup, the TX-1600 Noctua Edition will operate fully passive up to around 50% load at typical ambient temperatures (≤25°C) and only start ramping up the fan slowly as the load or temperature levels increase.
This makes it a fantastic choice not only for power-hungry high-end builds, but also for silent systems that do not require as much as 1600W and will therefore have the PSU running mostly with the fan switched off or at near-inaudible speed levels. Even at 100% load, the Noctua Edition runs whisper quiet at ambient temperatures up to 25°C, producing only ~24dB(A) versus ~34dB(A) for the regular model. This massive reduction in noise emission is reflected in an upgrade of Cybenetic’s Lambda average noise level score from A to A++.
Topped off with ATX 3.1 and PCIe 5.1 support as well as fully modular, Noctua-themed cables, the Seasonic PRIME TX-1600 Noctua Edition is the ultimate choice for highly demanding PC enthusiasts who require uncompromising quality, class-leading performance and exceptional quietness of operation.
• Key Features
Noctua NF-A12x25 120mm Fan: The crown jewel of PC cooling. This custom-integrated fan guarantees exceptional static pressure and airflow, cooling the PSU internals silently without the disruptive motor hum found in standard power supplies.
Semi-Passive Operation: Absolute silence during regular use. At ambient temperatures up to 25°C, the fan remains completely switched off until the system hits 50% load (800W).
ATX 3.1 & PCIe 5.1 Ready: Future-proof your investment. Equipped with the native 12V-2x6 connector, this PSU safely and efficiently powers extremely demanding GPUs like the NVIDIA RTX 4090 and upcoming 5090 series without requiring dangerous adapter cables.
Titanium-Level Efficiency: Boasting an 80 PLUS Titanium and Cybenetics ETA Titanium certification, it hits 94% energy efficiency at a 50% load, dramatically reducing waste heat and lowering electricity costs for machines running 24/7.
Custom Noctua-Themed Modular Cables: Build with flawless aesthetics. The fully modular design includes custom-sleeved cables in Noctua’s signature brown and black colorway, eliminating the need for expensive aftermarket cable extensions.
Optimized Fan Grill: Seasonic and Noctua completely redesigned the external fan grill to optimize aerodynamic airflow, smoothing out pressure gradients and eliminating turbulence noise.
• Performance / Technology
This PSU features state-of-the-art micro-tolerance load regulation (MTLR), keeping the output voltage within a remarkably tight 0.5% margin. This ultra-clean power delivery prevents system crashes and extends the lifespan of sensitive components like the motherboard VRMs and storage drives.
• Design & Ergonomics
The heavy-duty chassis features a premium two-tone black and Noctua-brown finish. Because it is fully modular, you only plug in the exact cables your build requires, significantly improving chassis airflow and keeping the rear cable management chamber spotless.
• Compatibility / Use Cases
Designed for the most demanding rigs on the planet. This 1600W titan is the mandatory power delivery choice for multi-GPU 3D rendering workstations, Threadripper/EPYC AI servers, and extreme custom-loop water-cooled gaming PCs.
• Why This Product Stands Out
Most 1600W power supplies sound like jet engines under load. The Seasonic PRIME TX-1600 Noctua Edition stands out by securing a Cybenetics Lambda A++ noise rating. Even at a blistering 100% load (1600W), it generates only ~24 dB(A) of noise, making it the only viable choice for audio engineers and creators who require massive computing power without background microphone interference.
