Product Overview
The Thermaltake ToughPower SFX Platinum series is a high-performance, modular power supply unit designed for compact Mini ITX builds. Available in 1000W, 850W, and 750W capacities, these units feature 80 PLUS Platinum efficiency, ensuring stable power delivery and reduced energy waste. The fully modular design allows for cleaner cable management by using only the cables required for your specific system configuration.
Safety Precautions
To ensure safe operation and maintain your warranty, please adhere to the following guidelines:
- Do not open the power supply casing; high voltages are present inside.
- Avoid operating the unit in environments with high humidity or extreme temperatures.
- Use only genuine Thermaltake modular cables. Third-party cables may be incompatible and cause severe damage to your components.
- Ensure the power source matches the rating label on the unit.
- Verify that all cable connections are secure and properly seated.
Installation Guide
Before installing, ensure your system is powered off and disconnected from the AC source. If replacing an existing unit, follow your computer case's manual for removal. For SFX installations, use the provided screws to secure the unit directly into the chassis. If using a Mini ITX case that requires an adapter, attach the SFX-to-ATX bracket first using the included screws. Connect the 24-pin motherboard cable, the 8-pin EPS12V cable (or 4-pin if required), and necessary SATA, PCI-E, and peripheral cables. Once all connections are verified, connect the AC power cord and toggle the power switch to the ON position.
Operation and Maintenance
These power supplies are equipped with a Smart Zero Fan feature. The fan will remain stationary during low-load operations to reduce noise and will automatically activate once the internal temperature reaches a specific threshold. If the system fails to power on, check that the AC cord is firmly connected, the I/O switch is set to 'I', and all internal connections are secure. If using an Uninterruptible Power Supply (UPS), ensure it is powered on and functioning correctly.
Technical Specifications
The units support a wide input voltage range of 100-240V. They feature comprehensive protection circuits, including Over Power Protection, Over Voltage Protection, Short Circuit Protection, and Over Temperature Protection. The MTBF (Mean Time Between Failures) is rated at over 100,000 hours, ensuring long-term reliability for your high-performance PC build.
