While the HKC version uses a higher-quality double-sided PCB, this one uses a plain single-sided PCB, usually found in low-cost PSUs. The FETs are also of lower quality. The CE-Link version uses a single bulk cap, while the HKC version uses two Rubycon ones, with lower combined capacity but of notably higher quality. The APFC and resonant controllers are the same, and the same applies to the controllers that handle the minor rails.

The primary topology and the design on the secondary side are also the same. The CE-Link version uses more electrolytic caps of decent quality and has three fewer polymer caps than the HKC version. Moreover, the supervisor IC is different.

A major difference is the cooling fan, which uses a true fluid dynamic bearing in the CE-Link version, while a plain sleeve/rifle bearing is used in the HKC version. Lastly, there are also differences in the 5VSB circuit, as expected.

CE-Link Made Unit HKC Made Unit

The CE-Link unit has a lower-quality PCB, which matters a lot in terms of performance, and its FETs are from a less-known manufacturer. The filtering caps on the secondary side are slightly higher quality, while its fan is notably better than the one used in the HKC model. Overall, the HKC unit’s design is superior, allowing for better airflow, especially on the secondary side.

  1. —“… a brand changes OEMs without changing the product’s name or providing some information on the box to help buyers distinguish the different versions.”

    Aris, is there at least some info on the outside of the unit when it’s not on the box?
    If not, that’s pretty rude 😈

  2. Totally blasted the Thermaltake Toughpower GF A3 750W ATX v3.1, but that’s fair enough.
    Failure to style by TT.
