Lian Li doesn't pack the cables in any special way. Each of these is encased in a plastic bag with all the components.
This variant of the Strimer Plus V2 ARGB extension cable can be considered the base, and as such includes the controller alongside two double-sided pieces of tape for mounting within your chassis. Lian Li also includes a Micro-USB to USB 2.0 header adapter for data transfer. Last but certainly not least, there is a set of white clips to replace the user-facing black ones pre-installed on the extension cable. A basic manual and marketing pamphlet round out the accessories.
The controller sports a permanently attached SATA cable for power. Next to that, you will find a small plug for motherboard lighting control and synchronization of any Lian Li products. To the right of that is a Micro-USB connector to communicate with the host system. At the opposite end is a large, proprietary connector for the ATX extension lead. You will find the same plug on the side next to a smaller variant as well. These two are for the PCIe cables, but only one may be powered at any given time by using the tiny switch between them. Alternatively, you could buy two 3x PCIe connector variants of the Strimer Plus V2, buy the controller separately, and route them to two massive GPUs. However, with multi-GPU setups essentially non-existent these days, that is quite the edge case.
A Closer Look
At first sight, the new Strimer Plus V2 cables look far cleaner than the V1 variants. Lian Li managed to make each ARGB string thinner, which results in a slimmer overall width. On top of that, by creating custom power wiring, the two components now fit together much better, making for a far thinner product, which in turn allows for tighter bend radii as well.
The 24-pin ATX cable comes with a 8-pin wide connector to utilize with the included controller. And while there is no need to take apart the cover to which this lead is soldered, doing so will reveal a flexible PCB and three groups of four ARGB strips combined into one.
Both ARGB strip ends are encased in black plastic, with the one attached to the PSU side sporting the company branding. This means you are unlikely to have any such labels visible in your build.
The end facing the motherboard may be taken apart as well, but it serves a purpose as you may switch to the white variant. Squeezing the clips back together is not complicated, but a bit of care is required to make sure they don't get damaged. Thanks to three guiding pins, one for each cable group, aligning the wiring is nice and easy.
