Thermaltake Toughpower PF3 1050W PSU Review

Protection Features

OCP (Cold @ 22°C) 12V: 121.8A (139.2%), 12.122V
5V: >30A (>150%), <4.985V
3.3V: >30A (>150%), <3.302V
5VSB: 5.3A (176.67%), 5.032V
OCP (Hot @ 41°C) 12V: 115.2A (131.66%), 12.12V
5V: >30A (>150%), <4.985V
3.3V: >30A (>150%), <3.302V
5VSB: 5.3A (176.67%), 5.033V
OPP (Cold @ 23°C) 1448.72W (137.97%)
OPP (Hot @ 40°C) 1329.68W (126.64%)
OTP ✓ (131°C @ 12V Heat Sink)

PWR_OK Proper operation
Fan Failure Protection
SIP Surge: MOV
Inrush: NTC Thermistor & Bypass relay

I am satisfied that OCP at 12V is close to 130% at high temperatures. The same goes for OPP, which drops notably at high temperatures, effectively protecting the PSU. On the contrary, OCP on the minor rails is set higher than it should be, especially at 3.3V.

  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?
