Power Supply|LIAN LI|SP750|SFX|100 - 240 V|750 W|G9P.SP0750G.W000.EU

The Lian Li SP750 is an SFX power supply delivering 750 W total power with 80 PLUS Gold efficiency. Its compact SFX form factor and brushed aluminium housing suit small and mid-size PC builds that require reliable, efficient power. The unit supports universal AC input (100–240 V, 50–60 Hz) and uses active power factor correction for stable electrical performance.

Advantages

The power supply features 80 PLUS Gold efficiency for lower energy loss and improved thermal behaviour, fully modular braided cables for simplified cable routing and a cleaner interior, and Japanese electrolytic capacitors for enhanced durability. A ZERO RPM mode keeps the fan off under light load for near-silent operation, while FDB bearing technology provides long-lasting, quiet cooling. The compact white enclosure combines a classic look with space-saving dimensions.

How to use

Install the SP750 into a compatible SFX or supported case following the case manufacturer’s PSU mounting instructions. Connect only the modular cables required for your components to maintain tidy airflow and reduce clutter. Ensure the AC input matches 100–240 V and use a properly rated mains cable. Check that system power requirements do not exceed the unit’s 750 W rating before use.

Recommendations

For optimal silence and longevity, enable ZERO RPM operation by keeping average system load below the fan start threshold and maintain good case airflow. Use high-quality modular cables and periodically inspect connections and capacitors for signs of wear.
