This platform is provided by Enhance Electronics and features very good build quality, despite an affordable price for this wattage category. The same high-end design is also used in SilverStone's ST1500-TI, which costs way more than the KL-C1500PL. Kolink's offering even has more efficient primary switching FETs and higher-capacity bulk caps. Everything else is exactly the same between the two PSUs.
We find a full bridge topology on the primary side, along with an LLC resonant converter. On the secondary side, the DC-DC converters are installed on a PCB right behind the modular board in an effort to minimize energy losses. Finally, the +12V FETs are installed on the main PCB's solder side, and are mainly cooled by the chassis.
Ripple filtering is mainly done by polymer caps, with the few electrolytic ones being provided by respected manufacturers. This is a key feature, since capacitor quality on the secondary side plays a major role in a PSU's reliability.
The following video shows the KL-C1500PL’s internals.

ozicom "The problem we see is that all eight-pin connectors have the same pattern, making it possible to accidentally connect an EPS cable to a PCIe socket and vice versa." Well I had a fully modular PSU in past and you can't connect eight pin of EPS to PCIe because the sockets may look same but they're not. If you look closer on top left two sockets of black and blue eight pins the notches are not same so you can't connect it. But if you tried and connect it it's a problem of course.Reply
