Power Supply Unit Thermaltake SFX-750AH8FKG 750 W

The Thermaltake SFX-750AH8FKG 750 W power supply unit is a compact SFX-format PSU intended for small form factor desktops and compact server builds. It delivers up to 750 watts of continuous power while occupying less space than standard ATX units. The unit is 80 PLUS Gold certified for high efficiency and includes a 24-pin ATX motherboard connector plus a full set of power leads for CPU, PCIe, peripheral (Molex) and SATA devices. An integrated 92 mm cooling fan and an AC input range of 100–240 V with 50–60 Hz compatibility help maintain stable operation across different regions and workloads.

Advantages

The 80 PLUS Gold certification ensures efficient energy conversion and reduced heat generation compared with lower-efficiency models. With a rated output of 750 W, the PSU supports demanding multi-component systems while remaining suitable for compact chassis due to its SFX form factor. The included 92 mm fan provides active cooling optimized for constrained spaces, and the set of standard power connectors covers common motherboard, CPU, GPU and storage device needs. The wide AC input voltage range allows reliable operation in varied power environments.

Suitable for

• Small form factor (SFF) gaming or workstation PCs that require up to 750 W
• Compact server or home lab builds with limited internal space
• Systems needing 24‑pin ATX, CPU and multiple PCIe and SATA power connections
• Environments where energy efficiency and lower heat output are priorities

How to use

Install the Thermaltake SFX-750AH8FKG in a compatible SFX or SFX-to-ATX adapter bay following the chassis manufacturer’s instructions. Connect the 24‑pin ATX cable to the motherboard, attach the CPU power connector to the appropriate EPS/CPU socket, and route PCIe, SATA and peripheral cables to graphics cards and storage devices as required. Ensure the AC mains cable is properly connected to a grounded outlet and that the PSU receives adequate ventilation. Verify BIOS and component power requirements before first startup and monitor system stability during initial operation.

Recommendations

Use this PSU in cases that provide adequate airflow and avoid obstructing the 92 mm fan intake. Match the unit’s 750 W capacity to the combined power draw of CPU, GPU and peripherals, leaving headroom to prevent sustained near‑maximum loads. For systems with high transient demands, allow for a margin above typical peak consumption and follow manufacturer guidance for cable routing and connector seating to maintain reliable power delivery.
