This is a typical modern platform featuring good soldering quality and top-notch parts, which is why the price is high. The best Japanese capacitors and Infineon FETs don’t come cheap. On the solder side of the PCB, the soldering quality is good, which is expected given that Great Wall uses state-of-the-art equipment, but there is nothing to see since all parts are on the other side of the PCB. A half-bridge topology and an LLC resonant converter are used on the primary side. On the secondary side, a synchronous rectification scheme is used for the 12V rail, which feeds a pair of DC-DC converters to generate the minor rails—the usual stuff for a modern PSU platform.
All capacitors are made by Japanese manufacturers, so they will easily outlive the PSU’s warranty period. The cooling fan is made by Hong Hua, so it is also reliable.

这是一个典型的现代平台，以其良好的焊接质量和一流的部件而闻名，这也是价格较高的原因。最好的日本电容器和英飞凌场效应晶体管（FETs）并不便宜。在PCB的焊接方面，焊接质量是好的，这是意料之中的，因为长城使用了最先进的设备，但由于所有部件都在PCB的另一侧，所以看不到。在主侧使用了半桥拓扑结构和LLC谐振转换器。在次级侧，12V轨道使用了同步整流方案，这为一对DC-DC转换器供电以产生次级轨道——这是现代电源供应平台的常见配置。
所有的电容器都是由日本制造商生产的，因此它们将轻松超过电源供应器的保修期。冷却风扇是由宏华制造的，所以它也是可靠的。
Manufacturer “Great Wall”, in the country with the “Great Wall”.
Fucking comedy 😀
Nobody ever gave the Chinese credit for being “creative”.
