Packaging and accessories

The TX-1600 comes in a hefty, almost mirror-like box. In typical Seasonic fashion we find the specifications of the PSU on one side while more information such as efficiency graphs and other features are listed at the back.


Opening the box we are greeted by a user manual and installation guide (both also available online) together with a set of zip-ties, Velcro strips, mounting screws and some stickers.


The PSU comes in a soft pouch. The massive set of cables also comes within its own pouch.


As all the cables of the PSU are individually sleeved, Seasonic provides a set of "combs" to organize them nicely in a case.


A separate accessory not common to other supplies is the angled 24 pin connector with the PSU test functionality. While the single button testing functionality is very basic, the ability to connect the 24 pin cable to the motherboard might be handy, especially with some cases.



Within the modular cable bag we find a plethora of cables (the full list of lengths is mentioned in the table below) as well as an AC cable with a C19 connector - common for high wattage units.

Cables

With six individual 6+2 pin PCIe power connectors and two 12VHPWR connectors (specced to deliver up to 600 W each), the TX-1600 is sufficient for the most demanding gaming or workstation setups. The inclusion of three EPS 12 V cables is also welcome and could potentially be used when building a workstation/server setup, which may not utilize the typical 24 pin ATX connector, but instead need up to three 8 pin EPS 12 V connectors.

The SATA ports on the peripheral cables are spaced 15 cm apart while the Molex cable connectors are spaced 12 cm apart.

As mentioned earlier, all cables have individually sleeved wire strands that can be shaped with the help of the included combs. One exception is the 12VHPWR cables where the four thinner sideband signal wires are stuck together.

None of the cables feature any inline capacitors for ripple/noise suppression.
