Thermaltake Toughpower PF3 1050W PSU Review

Box & Bundle

The box provides good protection. At its face, we find a quarter-shot of the PSU and a series of badges describing the product’s main features. For more details, look at the backside.

Product Photos

All intake and exhaust grilles are punched into the PSU’s chassis. The fan’s grille is too restrictive, not helping for optimal airflow. The modular panel has twelve sockets. It is the same with the 1200W model.


Modular Cables
Description Cable Count Connector Count (Total) Gauge In Cable Capacitors
ATX connector 20+4 pin (600mm) 1 1 16-22AWG No
4+4 pin EPS12V (650mm) 2 2 16AWG No
6+2 pin PCIe (500mm+150mm) 2 4 16-18AWG No
6+2 pin PCIe (500mm) 1 1 16-18AWG No
12+4 pin PCIe (600mm) (600W) 1 1 16-26AWG No
SATA (500mm+145mm+145mm+145mm) 3 12 18AWG No
4-pin Molex (500mm+150mm+150mm+150mm) 2 8 18AWG No
FDD Adapter (150mm) 1 1 22AWG No
AC Power Cord (1380mm) – C13 coupler 1 1 16AWG

There are enough cables and connectors for smooth power delivery. The 12+4 pin connector is set for 600W power delivery. The number of 4-pin Molex connectors is more than enough; I am not sure if anybody will need more than four, but since they are modular, there is no harm. Lastly, some cables use thicker gauges for lower voltage drops at high loads. The cable configuration is the same as the 1200W model.

  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?
