Unboxing, product images and scope of delivery
The packaging usually shows a photo of the power supply unit on the front. Inside, the protection provided is adequate.
This power supply has an unusual design due to the extended modular panel, but this could be practical for some users. I particularly like the fact that the top fan cover can be easily removed thanks to the magnetic attachment. The AC connection and power switch are located on the front of the power supply unit. On the opposite side, there are 13 sockets, including a 12V-2×6 socket. Although there is only one native 12V-2×6 socket, Lian Li has included two corresponding cables, with the second cable ending in two 8-pin plugs.
On the rear is the modular panel with 20 connectors, including two native 12V-2×6 connectors. Right next to these are two smaller connections with additional sense pins. There is also a switch labeled “5V Boost” on this side, which raises the voltage of the 5V rail to ensure a more stable supply for increased loads.
This power supply comes with many cables, including two EPS cables, four legacy cables and two high-power PCIe cables. Numerous peripheral cables are also included, and the distance between most of the plugs is sufficiently large at 150 mm. All cables are quite long overall, especially the EPS cables, so there should be no compatibility problems even with particularly large cases.
The table reads like this:

Protection circuits
The tripping thresholds of the OCP (Over Current Protection) for the 12V rail are conservatively set. The overload protection threshold (Over Power Protection, OPP) is below 130% at normal temperatures and noticeably lower at high temperatures.
However, the situation is different for the secondary rails, where the corresponding OCP trigger thresholds are set quite high. Even more problematic is the fact that the OCP trigger thresholds of the secondary rails are even higher at high temperatures than at normal temperatures. As a rule, it should be the other way around so that the power supply unit is better protected under load at high temperatures.
