Landing at the high end of the power supply spectrum, the TX-1600 delivers top-tier efficiency and power ratings. One of the best manufacturers in the space, Seasonic, is known for its exceptional build quality and long warranties on premium models. Now, in collaboration with fan and cooling giant Noctua, Seasonic has upgraded the TX-1600, creating a new 1600W version.

With enough power to handle current components and future upgrades, this PSU is a serious long-term consideration for any high-end PC build. That said, it comes with a steep price tag and a distinctive colorway, which may not suit every setup. Here’s a closer look at what it has to offer.

What We Think

The Seasonic Prime TX-1600 Noctua Edition is a no-compromise power supply for some of the most powerful builds out there, with peak efficiencies. Blending in Noctua’s brown colorway with silent and high airflow cooling, the PSU offers a long-term solution for powering successive systems. It is an excellent option for those who can afford it since the premium unit gets an extra cost for the collab, and it can be hard to fit into every build. But it can definitely be a pick up now for over a decade.

Reasons to Buy
  • Some top design and build quality
  • Impressive Titanium efficiency and A++ sound rating
  • Long lasting 12 year warranty
  • Plenty of premium accessories included
  • ATX 3.1 and PCIe 5.1 compliance with native 16-pin connector
  • Lots of nice braided cables to use and expand over the years
Reasons to Avoid
  • Very expensive for most users
  • Way more power than most builds need
  • Too long for some cases
  • Noctua brown beige may not be to everyone’s tastes

Design

The moment you grab the box, the premium quality and sheer heft of the Seasonic Prime TX-1600 are immediately apparent. The size alone hints at just how substantial this PSU is – much larger than the typical units you might choose for mid-range builds. But the TX-1600 doesn’t compromise; it delivers maximum power without cutting corners on design or build.

Opening the box reinforces that impression. The PSU itself is sleeved in a soft protective bag and nestled in dense foam, while the accessories come in a sturdy pouch – perfect for keeping everything safe if you plan future upgrades. It’s clear this unit is built for longevity and heavy-duty performance.

Inside, the long black metal chassis of the TX-1600 dominates. Flip it over to the fan side, and the design surprises: Noctua’s signature brown-and-beige color scheme dominates the surrounding plate, with a centrally embedded NF-A12x25 120mm fan engineered for both quiet operation and high performance.

On the opposite side of the PSU, you’ll find a standard black metal panel featuring a large sticker that details the specs and features. The sides have angular indentations, while the brown metal from the fan side protrudes slightly, showcasing the “Prime Noctua Edition” branding.

In terms of connectivity, the TX-1600 is extremely well-equipped. It offers nine CPU/PCIe connectors, six peripherals, one motherboard, and two PCIe Gen 5 ports, giving you plenty of options to power high-end graphics cards directly through the 16-pin connector – all backed by the 1600W capacity of the unit.

On the power end, there’s the AC input along with two buttons. The power cable is custom-shaped for Seasonic’s PSU design, meaning it must be used as supplied. Beside it sits a large power switch and a hybrid-mode button, which allows you to adjust the fan behavior for quieter or more active cooling.

The accessory bag contains a set of braided cables in black and Noctua brown, which both look and feel premium. Cable combs are included to keep your build looking neat and stylish, and there’s also a 90° adapter and an integrated PSU tester that lets you jump-start the motherboard power connector if needed.

Size

The TX-1600 uses a standard ATX form factor, but it’s noticeably longer than typical lower-powered units, measuring 210mm. This extra length is an important consideration when planning your PC build, as some cases may have limited space for both the PSU and cable routing.

That was exactly the challenge I faced when installing the PSU in two different chassis: the be quiet! Light Base 500 LX and the Hyte X50. In both cases, space was tight. The Light Base 500 LX officially supports PSUs up to 200mm, while the Hyte X50 allows up to 223mm, so while installation is possible, it can be tricky to route cables neatly and fit the PSU comfortably.

Performance

Next up, I installed the tested power supply by installing it into the case and putting the components through their paces. Although we don’t have a proper PSU tester for in-depth looks, I got ot see how easy it is to use, the power it provides, and how loud it is in fact. Here’s the hardware we paired with it.

  • CPU: Ryzen 9 9800X3D
  • Motherboard: MSI MEG X870E Godlike X Edition
  • RAM: Corsair Dominator Titanium 64GB 6600
  • Cooler: ROG Ryujin II 360 AIO CPU cooler
  • GPU: ROG Astral RTX 5090 BTF OC
  • Case: be quiet! Light Base 500 LX

In that system, the main power components are the CPU and GPU, with a TDP of 120W (with a PPT of 162W) and 575W, respectively. Requiring a total of over 700W most of the time, ASUS ROG does recommend a 1000W power supply for the graphics card, not even close to the TX-1600, but certainly a high feat for most standard builds and PSUs.

Firing up Furmark 2 with CPU shark and GPU stress tests, it pinned the two to their maximum, pulling all the power from the power supply to them. Below you can find the results of that, which easily provides the full power required for the CPU and GPU.

Reaching 600W for the GPU and 148W on the CPU, providing over 700W of power across three power cables. More interestingly, HWinfo gives us an insight into the 12VHPWR connector. With each wire run averaging 8 Amps and nearly 100W in each of them.

Two graphs spanning thirty minutes with a 20 minute load in the middle of both. The top one shows CPU package power in red and GPU power in green. The bottom one shows GPU 12VHPWR connector current in red and it's average power in green.

For a more in-depth analysis, you can look at the Cybenetics testing done to give it the Titanium rating, the second-highest rating it gives out. There, it runs an average efficiency of over 93.9% and with a noise output of just 13dBa.

Price and warranty

The Titanium efficiency and 1600W rating of this power supply mean it’s not an affordable one. Seasonic makes premium PSUs, and adding an expensive Noctua fan and branding quickly adds up. So it now comes in at $654/£429. That is $95 over the standard TX-1600, making it even more high-end and premium. But when it comes to efficiency for years and with support for a long time, it definitely is a great consideration.

Especially as Seasonic offers a 12-year warranty on the power supply. 1600W and the native 16-pin power cables mean it will most likely last you for that amount of time, and with all the cables in there, be able to expand with your upgrades down the line. Along with saving you money on power, with the improved efficiency.
