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. Hello 🙂 Thank you very much for the review. I have two questions if you dont mind:

    1. On the product page they say the 12V-2×6 cable of this PSU has a temperature sensor and it sends signal the PSU to ensure safe operation. Did you test this. Is this a useful feature given the issues we have right now with melting connectors and cables or how is that supposed to work ?

    2. There is also a 5V boost button on the PSU. On the product page it says “When this switch is enabled, it boosts the +5V voltage to maintain optimal performance. If no voltage drop occurs, the PSU will regulate the +5V rail to approximately +5.15V, ensuring consistent power delivery.” For what scenarios is that useful or should i enable it all the time ?

    Thank you very much!

  2. Hey i saw the old cybernetics site of the psu (evaluations/psus/2616/) wasnt accessible anymore, instead there is a new site and test for this psu from yesterday (evaluations/psus/2737/).

    I noticed the PSU being much more silent and also having a better cybenetics lambda rating at 115 volts.

    Did anything else change? Will the article be updatet to reflect the better performance?

    Thanks in Advance.

    Also another Quick Question. I noticed the 1650 and 1300 Watt Version being nearly identical in their used components and all measurements being pretty close, so i guess, the 1300 Version is also an instant recommend?

    1. They changed the fan speed profile yes, and since this change will pass ASAP to the production, we didn’t want to have confusing results on our site.

      Updated PSU review, if I find the time I could yes.
      1300W is same platform is it has similar performance.

      1. Hello,

        thanks for the super fast answer. Nice, that they actually bothered to push an (imo pretty big) improvement (cutting the average noise in half from 26 to 16 dba) so early in the products lifetime. Sad you couldnt convince them getting that fan failure protection though as well. :P.

        Currently waiting on the 1300 being (again) available, will definitely get it.

        Hope they will be more Infos soon about the 5V boost setting and the additional temp sensor in AsRocks 12V 2×6 Cables. Cant rly wrap my head around the 5V boost usefulness. The Temp Sensor on the other hand might be even more needed, then before (Hope you get your hands on a 5090FE soon, for some more extensive testing beyond what der8auer was observing).
        Sadly their downloadable manual is currently just the quick install guide. Hope there will be a proper manual soon with more Infos about both features.

        Have a nice day.

  3. 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 🙂

  4. 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.
