Designed for high-end gaming and professional workstations, it offers whisper-quiet operation with semi-passive cooling, exceptional power stability, and a clean, customizable cable setup for the ultimate silent powerhouse build. ## Description 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. ## Features - Ultra-quiet Noctua Edition of the award-winning Seasonic PRIME TX-1600, state-of-the-art electrical performance with steadfast power delivery and ultra-tight voltage regulation for high-performance workstations and gaming PCs - with US AC power cord - Renowned Noctua NF-A12x25 fan and custom designed, highly optimised fan grill for extremely low noise levels (Cybenetics Lambda A++ certification), ~8-10dB(A) quieter than the regular PRIME TX-1600 - Semi-passive operation: Fan stays off until 50% load at up to 25°C ambient temperature for virtually noise-free operation, slowly ramps up to near inaudible levels with increasing loads: Perfect for powerful PC builds that run almost silent! - ATX 3.1 and PCIe 5.1 compliant, 12V-2×6 connector for safely powering high-end graphics cards such as NVIDIA GeForce RTX 4090 series, backwards compatible with ATX 3.0 and PCIe 5.0 - Fully modular, Noctua themed cabling for clean and tidy builds, titanium level energy efficiency (94% at 50% load, 80 PLUS Titanium and Cybenetics ETA Titanium certified) reduces waste heat and power consumption ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0DMW5F3GG | | Brand | Noctua | | Compatible Devices | Personal Computer | | Connector Quantity | 3 | | Connector Type Used On Cable | ATX | | Cooling Method | Air | | Current Rating | 1600 Amps | | Customer Reviews | 4.7 4.7 out of 5 stars (123) 4.7 out of 5 stars | | Form Factor | ATX | | Item Dimensions | 21 x 15 x 8.6 centimeters | | Item Weight | 5.86 Kilograms | | Lower Temperature Rating | 25 Degrees Celsius | | Manufacturer | Noctua | | Maximum Input Voltage | 240 Volts (AC) | | Mfr Part Number | Seasonic PRIME TX-1600 Noctua Edition US | | Minimum Input Voltage | 100 Volts (AC) | | Model Name | Prime TX-1600 Noctua Edition | | Model Number | Seasonic PRIME TX-1600 Noctua Edition US | | Number Of Fans | 1 | | Number Of Items | 1 | | Output Wattage | 1600 Watts | | Power Supply Design | Full Modular | | System Bus Connector Type | ATX | | Upper Temperature Rating | 25 Degrees Celsius | | Wattage | 1600 watts | ## Product Details - **Brand:** Noctua - **Compatible devices:** Personal Computer - **Connector type:** ATX - **Model name:** Prime TX-1600 Noctua Edition - **Output wattage:** 1600 Watts ## Images ![Seasonic Prime TX-1600 Noctua Edition, Ultra-Quiet Fully Modular 1600W 80 Plus Titanium Efficiency ATX 3.1 PC Power Supply (Black/Brown) with US AC Power Cord - Image 1](https://m.media-amazon.com/images/I/71ZLjg+I-ML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ My favorite power supply ever made *by on Reviewed in the United States 4 June 2025* The Seasonic Noctua Edition 1600 Power Supply is the highest quality power supply I have ever touched. The attention to detail, such as the inclusion of a motherboard power cable 90° adapter, fully braided cables right out of the box, and other goodies makes this feel like a premium and complete package. I used to order CableMod cables for all my power supplies, but I don’t feel the need with this one thanks to the included braided cables.One thing to note right off the bat is that this power supply is heavy. If you will be lifting your PC case a lot, it adds heft. I also have this strange issue where there’s an arcing sound from the power supply when turning on my PC at startup, but it only lasts a second and stops. I am awaiting Seasonic’s reply on that, but from what I’ve read, this might be normal when energizing the components for the first boot after being unplugged for a while.Lastly, I think it offers great performance, my system only pulls about 700-800W max with an NVIDIA RTX 5090 founders edition and AMD Ryzen 9 9950X3D combo. But the extra headroom means I’m staying efficient and have plenty of room for upgrades in the future. Given the bulletproof reputation of this power supply, I plan to keep it for a long time.Oh, and the Noctua fan is quiet. I don’t even hear it. ### ⭐⭐⭐⭐⭐ Whisper Quiet high power PSU *by on Reviewed in Canada 22 August 2025* Exactly what I was looking for. I build a new computer with a custom water loop with no expense including an RTX 5090. When I finished it I wasn't happy has even tho it looked amazing, everything was silent except the Power Supply, when the 5090 was being pushed you would hear the fan of the power supply ramping up and it made it such a downer considering that everything else in the system was whisper quiet. So I decided to bite the bullet and go with the 1600 TX Noctuah edition... Now the whole system is whisper quiet at all time ... exactly what I was looking for... the quality of this PSU is amazing and definitely feels premium. ### ⭐⭐⭐⭐⭐ Amazing PSU *by on Reviewed in the United States 13 August 2026* This PSU is a monster it reduced my coil whine on my Rtx5090. My total system pull is around1000watts so it should be around the sweet spot of this power supply. It's kinda long, the cables feel really premium, with a metal construction. Really high end PSU. ## Frequently Bought Together - Seasonic Prime TX-1600 Noctua Edition, Ultra-Quiet Fully Modular 1600W 80 Plus Titanium Efficiency ATX 3.1 PC Power Supply (Black/Brown) with US AC Power Cord - Noctua NF-A14x25 G2 PWM, Premium-Quality Quiet 140mm PC Fan, 4-pin (Brown) - Noctua NH-D15 G2 LBC, Dual Tower CPU Cooler, Specialised Low Base Convexity Version for AMD AM5/AM4 (Brown) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/742274976-seasonic-prime-tx-1600-noctua-edition-ultra-quiet-fully-modular](https://www.desertcart.jp/products/742274976-seasonic-prime-tx-1600-noctua-edition-ultra-quiet-fully-modular) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-29*
