Thermaltake Toughpower PF3 1200W PSU Review

Thermaltake’s Toughpower PF3 1200W Platinum power supply is finally on our test bench, and it’s designed to power the most demanding gaming rigs and workstations, with 1200W of power more than meeting the demand of most extreme builds. It’s built with high-quality components and adheres to the latest standards, as you might expect, ensuring stable performance and reliable power delivery under intense workloads.

This PF3 series fully embraces the ATX 3.0 specification, meaning it can easily handle the transient power spikes of next-gen graphics cards. It’s also ready for PCIe 5.0, with a native 12VHPWR connector that can deliver up to 600W of power to your GPU through a single cable. I love this cable, as it’s much easier than routing two or even three 6+2 cables like we did on the last gen of GPUs/PSUs.

System builders will appreciate the compact 140mm depth of the Toughpower PF3. This makes it compatible with a wider range of cases, such as those with limited space and is certainly a stand-out feature given the power output is so high. The fully modular design is going to appeal too, allowing you to use only the cables you need, minimising clutter and maximising airflow within the case.

Thermaltake has prioritised reliability with the Toughpower PF3. It utilizes 100% high-quality Japanese capacitors, which are well respected due to their increased durability and performance at high temperatures. Plus, with the 80 PLUS Platinum certification, it guarantees exceptional efficiency which at 1200W is really important, and a nice upgrade from the previous model, the GF3, which was rated 80 Plus Gold at 1200W.

Key Features

  • ATX 3.0 and PCIe 5.0 ready: Supports the latest hardware and power delivery standards.
  • Native 12VHPWR connector: Powers high-end graphics cards with a single cable.
  • 100% Japanese capacitors: Ensures reliability and stability.
  • 80 PLUS Platinum certified: Guarantees high efficiency and low energy waste.
  • Compact 140mm depth: Offers wider case compatibility.
  • Fully modular design: Provides flexibility and clean cable management.

Power Delivery

The Toughpower PF3 1200W Platinum features a single +12V rail design with a maximum output of 100A, delivering the full 1200W to components such as CPUs and GPUs. This single-rail configuration ensures compatibility and simplifies power distribution within the system. The +3.3V and +5V rails offer a combined 100W of power with a maximum output of 20A each, providing power to motherboards, drives, and peripherals. Finally, a dedicated +5VSB rail delivers 15W (3A) for standby power.
