How to Install Thermaltake Toughpower GF A3 Snow 1050W

• Power down your PC, unplug the power cord, and discharge any remaining residual electricity. Open the case to access the PSU mounting area.
• Remove the existing power supply or prepare the new location. Align the Toughpower GF A3 Snow with the screw holes in the case’s PSU bay and ensure there is ample clearance for cables behind the motherboard tray.
• Secure the PSU to the case using the included screws. Tighten the screws evenly and do not overtighten to avoid damaging the chassis or the power supply.
• Connect the motherboard power: attach the 24-pin ATX connector and the 8-pin (sometimes 4+4) CPU power connector to the motherboard. Ensure solid, locked connections for reliable startup and stable voltage delivery.
• Power the graphics card and storage devices: attach PCIe power cables to the GPU (including the PCIe Gen 5.0 12VHPWR connector if your GPU requires it) and connect SATA/Molex power cables to drives or peripherals as needed.
• Route cables to maximize airflow and minimize obstruction. Use cable ties or Velcro strips to secure loose cables along the case interior, keeping them out of fans and intake/exhaust paths.
• Double-check all connections, re-check routing, and close the case. Plug in the power cord and power on the system to verify startup and stable operation under load. If you encounter issues, re-check all PSU connectors and ensure compatibility with your hardware.
