The Seasonic PRIME TX-1600 Noctua Edition is a sizable power supply unit, which is expected given its high output and premium design. As a special collaboration between Seasonic and Noctua, the PSU arrives with generous inclusions that reflect its flagship status. Accordingly, the packaging itself is notably large, hinting at the level of care and presentation that went into this exclusive edition.
The packaging carries Noctua’s signature brown colour scheme, immediately distinguishing it from the standard PRIME TX series. Both the Seasonic and Noctua logos are prominently displayed on the box, accompanied by several key certification markings that highlight the PSU’s efficiency and reliability standards.
More certifications and badges found on the side of the box.
Seasonic has thoughtfully included QR codes on the packaging linking to the 12V-2x6 Installation Guide and the User Manual. These provide easy access to compatibility details and other technical information that aren’t printed on the box itself — a convenient touch for users who want immediate access to essential documentation.
The side of the box features a brief product description outlining what sets the Noctua Edition apart, including details about its optimised acoustic profile and near-silent operation.
Two graphs printed on the packaging illustrate the Noctua Edition’s reduced noise levels and enhanced airflow compared to the standard PRIME TX-1600. These highlight that the collaboration goes beyond simply fitting a Noctua NF-A12x25 fan — the redesigned fan grille also contributes to improved airflow and overall acoustic performance.
Upon opening the box, the cables and accessories are neatly organised within a fabric pouch, giving a premium first impression. A user manual and installation guide are also included — the manual itself styled similarly to Noctua’s product documentation, which is a thoughtful detail. The power supply unit is securely protected by dense foam inserts, ensuring safe transport and presentation.
The power supply unit is inside a fabric hamstring bag.
The accessory pouch includes more than just the modular cables and power cord. Inside, there’s a small bag containing cable combs, another with Velcro straps, zip ties, and a Noctua badge sticker, as well as a Seasonic ATX 24-Pin 90° Adapter featuring an integrated PSU tester function — a practical inclusion for quick functionality checks.
Pre-installation Testing
Seasonic provided the necessary accessory to allow users to test the PRIME TX-1600 Noctua Edition power supply unit before installing to the system.
Power Supply Installation Guide
Seasonic recommends testing the power supply before installation, as outlined in the included quick-start guide. While the guide illustrates the traditional paperclip method, this is no longer necessary — Seasonic provides a dedicated PSU tester in the box. This small device allows users to safely and conveniently power on the unit for preliminary testing, offering a more reliable and user-friendly alternative to the manual paperclip approach.
Seasonic ATX 24-pin 90° Adapter and PSU Tester Function
The PRIME TX-1600 Noctua Edition includes a Seasonic ATX 24-pin 90° Adapter and PSU Tester Function — an exclusive accessory not available separately. This dual-purpose device enables quick functionality testing straight out of the box and doubles as a right-angle connector, helping achieve tidier cable routing once the PSU is installed.
To perform a test, simply connect the 24-pin cable to the PSU, then attach the tester to the other end of the cable. Plug in the C19 power cord and switch on the power supply. Press the button located at the centre of the ATX 24-pin 90° Adapter and PSU Tester — a blue light indicates that the unit is functioning correctly, while a red light signals a potential fault.
Cables
The cables included with the Seasonic PRIME TX-1600 Noctua Edition follow Noctua’s distinctive aesthetic, featuring a refined black-and-brown colour scheme that complements the PSU’s design and aligns seamlessly with Noctua-themed system builds.
The PRIME TX-1600 Noctua Edition features fully modular cables finished in Noctua’s signature black and brown colour scheme. Seasonic includes two 12V-2x6 cables, each measuring 700mm in length, along with three EPS cables for CPU power delivery. For legacy graphics cards, the PSU also provides six 8-pin (6+2) PCIe cables. Notably, these PCIe cables are not daisy-chained — or “pigtail” style — meaning users will need to connect two separate cables when powering GPUs that require dual 8-pin connectors, which is the recommended configuration for optimal power stability.
As expected from a high-end power supply, the included cables feature individually sleeved premium wiring, offering a more durable and visually refined finish compared to standard flat black cables.
The Seasonic PRIME TX-1600 Noctua Edition includes the following cables:

C19 Power Cord (Right)
The Seasonic PRIME TX-1600 Noctua Edition uses a C19 power cord, which is noticeably thicker than the standard C13 cables typically bundled with lower wattage PSUs. The C19 connector is designed to handle higher current loads — up to 16 amps — making it more suitable for high-capacity units such as this 1600W model. In contrast, C13 power cords are generally rated for up to 10 amps and are used for mid-range power supplies. The use of a C19 cable ensures safer and more stable power delivery under heavy load conditions.
