Thermaltake Toughpower PF3 1050W PSU Review


The Thermaltake Toughpower PF3 1050W achieves high enough overall performance and is close to most competitors. The main problem is that the notably less expensive GF A3 1050W achieves higher overall performance with a 1.7% difference. Sure, the latter doesn’t use the same quality caps to decrease the production cost, but it has a better fan, provided by Hong Hua! This is at least the case in my review sample. I cannot help but be confused about TT and HKC; instead of using a better fan in the more expensive unit, they used one in the less expensive PSU. And to make things worse, the less expensive PSU achieves a higher overall performance. Talk about internal competition! To add insult to injury, the GF A3 1050W is notably less noisy than the PF3 1050, with a 26.05 dBA average noise output compared to the 32.84 dBA the latter achieves. All of the above means that I cannot recommend the PF3 over the GF A3 1050 unit, especially since both are covered by the same warranty period, so if the lower quality caps of the second decide to leave this world, you will be covered by TT.

Several changes are required to bring the PF3 1050W up to speed, including a better fan speed profile and a close inspection of the production line to ensure all units have low-performance differences. Advanced production lines provide fully automated testing, not only once, so it is easy to check for high-performance differences and take action with the proper equipment. I don’t know if HKC’s production lines have this capability, but it is crucial.

  1. Hello,
    I have a strange thing to report about this exact model.
    I thought the fan on the unit I had was dying because of a somewhat scratching noise when disabling smart fan off so I ordered a replacement unit from Amazon

    The replacement unit is totally different from the one that I have. I have uploaded two photos of actual units and their boxes.

    My previous unit seems to have the same pcb as in your review, only with two brown Nippon chemicon 470uf instead of your’s black Nichicon.
    The newer unit seems to have:
    – the fan partially wrapped in plastic in order to restrict airflow (I Guess)
    – black thick heatsink similar to those of a cwt puq I had
    – just one black Nichicon with 400v stamped on it and GG (M) (no micro Farad indication that I can get a glimpse of)
    – different main transformer in a black monolith enclosure saying pq4040-a 2316 on it
    – three big nude coils similar to those of PFC (but I am no expert)
    – a fan that is even noisier (it resemble a track) when activated.
    – different advertisement about efficiency and fan curve on the box (see the photo attached)
    – cables pcb is disposed differently

    I can attach a sound print in mp3 of both if needed.

    I thought my fan was already defective but it seems this is even worse in a way. Wich one do you think would be better to keep?
