The performance the Kolink KL-C1200PL achieved is much higher than I expected. Its old platform is capable of achieving amazingly high efficiency levels; however, the absence of several protection features troubles me, and I believe that this fact probably plays a part in the unit's increased efficiency. In any case, at around €190 (excluding VAT), you get a very strong and fully modular PSU that is capable of delivering its full power under even extremely tough conditions. The exclusive use of Japanese caps is a really good thing since it will definitely increase the unit's reliability while keeping its performance levels rather stable as time goes on. If only High Power had used more filtering caps in the secondary side to further suppress ripple at +12V. Actually, if ripple were lower on this rail, the KL-C1200PL would have easily hit a much higher relative performance score, leaving many more expensive PSUs behind.

The increased inrush current, reduced hold-up time, high EMI transmissions, and lack of OTP, along with its improperly implemented protection features, are the major flaws of this PSU. On the other hand, you do get a PSU capable of delivering 1.2 kW under all conditions without it breaking the bank, and with a fully modular cable design, support for multiple high-end VGAs, pretty good transient response, and efficiency levels many Platinum platforms based on LLC resonant converters would envy. I am still very curious to learn about how High Power's engineers managed to achieve such high efficiency with such an old platform and the aged CM6800TX controller, though, which was very popular several years ago. The five year warranty might not look as impressive nowadays considering the ten years EVGA and Corsair provide and the twelve years of the Seasonic Prime models, but the Kolink offering costs significantly less than other high-end offerings of similar capacity. On top of that, I personally find a five-year support period to be quite long, especially because a PSU is susceptible to environmental factors and the mains quality.
