Product Information
The TOUGHPOWER GF A3 power supply is available in four wattage options – 1200W, 1050W, 850W, and 750W. It comes with various power connectors such as the main power connector (24-pin), ATX connector (4+4 pin), SATA connector (5-pin), PCIe connector (6+2 pin), PCIe connector (12+4 pin), peripheral connector (4-pin), and floppy adapter (4-pin). The power supply delivers continuous power and has an input voltage range of 100-240V with a frequency range of 50Hz-60Hz. It also comes with a user manual, mounting screws, and cable straps.
Product Usage Instructions
- Make sure your system is turned off and unplugged before installation.
- Disconnect the AC power cord from your old power supply.
- Place the TOUGHPOWER GF A3 power supply unit in your computer case.
- Connect the main power connector (24-pin) to your motherboard.
- Connect the ATX connector (4+4 pin) to your motherboard if required.
- Connect the SATA power connector to devices with a Serial ATA interface.
- Connect the PCIe power connector (6+2 pin or 12+4 pin) to the PCI-E graphics cards if required.
- Connect the peripheral power connector (4-pin) to peripheral devices if needed.
- Connect the AC power cord to the power supply and turn it on by pushing the switch to the ON position (marked with I).
- Note that when the Smart Zero Fan mode is turned on, the fan will not spin until the load exceeds 40% (30% for 1050W/1200W) of the power supply, minimizing the fan noise. It is normal if the fan does not operate when the computer is at a low working load.
- Make sure to comply with all warnings and cautions mentioned in the user manual to avoid damage to your components and voiding the warranty.
Note: Please use only genuine Thermaltake modular cables with Thermaltake power supply models. The warranty is voided with the use of third-party cables.

Installation Steps
Note: Make sure that your system is turned off and unplugged. Disconnect the AC power cord from your old power supply.
Step 1
Removing Your existing power supply
- Make sure that your system is turned off and unplugged.
- Disconnect the AC power cord from your wall outlet or UPS and the existing power supply.
- Disconnect all the power cables from your graphic card, motherboard, and all other peripherals.
- Follow the directions in your chassis manual and uninstall your existing PSU.
Step 2
- Make sure the power supply’s AC power cable is not connected.
- Follow the directions in your chassis manual and install the power supply with the screws provided.
- Connect the 24-pin or 20-pin main power cable to the motherboard.
- Connect the eight-pin +12V (EPS12V) cable to the motherboard.
- If your motherboard has an eight-pin +12V socket, connect the eight-pin cable directly to your motherboard.
- If your motherboard has a four-pin socket, detach the four-pin from the eight-pin cable, and then plug this four-pin cable directly to your motherboard.
- Connect the peripheral cables, PCI-Express cables, and SATA cables.
