Overview

The Lian Li SP750 is a 750W SFX form factor power supply designed for compact PC builds. It achieves 80PLUS GOLD certification, ensuring high power conversion efficiency. The fully modular cable design provides maximum flexibility for cable routing and optimizes airflow inside the case. This unit is engineered for high-end configurations in space-constrained environments such as Mini-ITX and some Micro-ATX cases. The 750W output offers sufficient headroom to drive mid-range to high-end graphics cards and CPUs simultaneously. Combining Lian Li's renowned build quality with the compact SFX standard, the SP750 is a solid choice for builders who prioritize both performance and space efficiency.

Compatibility Guide

Form factor: SFX (SFX12V V3.3 compliant). Compatible with SFX-ready cases, and can also be installed in standard ATX power supply mounts using the included SFX-to-ATX bracket. Connectors: ATX 24-pin, EPS 12V (4+4 pin for CPU), PCIe 6+2 pin, SATA, peripheral (4-pin). The 750W rating is recommended for builds with GPUs up to RTX 4070 class and CPUs up to Ryzen 7 / Core i7 class. For high-end configurations (RTX 4080+ / Ryzen 9 / Core i9), consider a higher wattage unit. Cable lengths are standard for SFX. When using the ATX bracket in a full-tower case, some cables may not reach distant connectors. Verify cable routing paths in your case beforehand.

Product Info

Released in 2022, the Lian Li SP750 is positioned as a mid-range to high-end SFX power supply. Its 80PLUS GOLD certification ensures reliable efficiency. The warranty period is 7 years (subject to manufacturer confirmation). It is available through major online retailers such as .

Best Use Cases

Compact gaming PC builders: Ideal for Mini-ITX or small Micro-ATX cases paired with GPUs like the RTX 4060 Ti or RTX 4070. The fully modular design simplifies cable management in tight spaces. Users prioritizing quiet operation: Standard noise levels for an SFX unit, with the 80PLUS GOLD efficiency reducing heat output and helping to keep fan speeds low. Enthusiasts who value clean cable management: The fully modular design allows you to detach unused cables completely, eliminating clutter inside the case.

Things to Consider

The 750W capacity may be insufficient for high-end GPUs such as the RTX 4080 Super or RX 7900 XT. For such builds, consider an 850W+ SFX unit (e.g., Cooler Master V850 SFX GOLD). SFX power supplies typically use smaller fans than ATX units, which can result in higher noise levels under heavy load. Be prepared for increased fan speed during demanding tasks. When using the included SFX-to-ATX bracket, the mounting position may shift slightly depending on the case. Check clearance in your specific chassis before installation. * Competitors include the Corsair SF750 Platinum and Cooler Master V750 SFX GOLD. The SP750 may be priced higher at times, so price comparison before purchase is recommended.
