The large PCB is overloaded with parts. FSP didn’t use large heatsinks, but enough space between the parts allows for good airflow. Several daughter boards are used to save space, including two large and an enormous one. It is always good to see large electrolytic caps on the secondary side since the more the capacity, the better the transient response.

FSP used a bridgeless APFC converter to increase efficiency, where FETs are used instead of bridge rectifiers, which contain SBRs. A Texas Instrument IC controls the APFC converter, while a Champion controller handles the primary side’s switching FETs and a part of the secondary side. The 12V rail is regulated through twelve FETs, and the same rail feeds a pair of DC-DC converters, which generate the minor rails.

The build quality is high; the same goes for the soldering quality. FSP used branded Japanese caps everywhere and Infineon FETs on the secondary side. The cooling fan is by Power Logic. This brand has higher quality products than Hong Hua but is more expensive, so most brands prefer the latter. For me, Power Logic fans are the real deal, and I am happy to see them again at PSUs.

  1. Hey how are you.

    I am currently thinking about a PSU that is Future proof 1200w+ with Dual 2x 16 Pin Connectors.

    I am currently evaluating between

    NZXT C1500 Platinum
    vs
    1300 Taichi / Gold Series

    I have read that the c1500 has wrong ocp/opp values, but the Asrock Models dont have Fan Failure Protection.

    What is more Important, and what would you advice me too buy from the Models:

    NZXT1500C
    Phantom Gaming Gold 1300/1600
    Taichi 1300

    🙂 The Noise doesnt matter i have headset 🙂

  2. Wouldn’t have expected AsRock to enter that space but it’s always a welcome surprise to see new competition. Are there any plans to also test their SL-G and PG-G units?

      1. Interestingly, ASRock Phantom and Taichi have the same specifications for the 1600 and 1300 units.
        The only differences are in the Gold efficiency for the Phantom units and Titanium for Taichi ones,
        and the number of connecting cables for the 1600 and 1300 models.
