Who it fits
Good fit for
You should consider this power supply if you are building a small form factor PC. The SFX size fits cases that do not accept standard ATX units. The 750 watt output handles mid-range GPUs and CPUs. The 80 Plus Gold rating ensures better energy efficiency. This reduces heat and power waste. The fully modular design lets you use only the cables you need. This helps with cable management in tight spaces. It suits builders who prioritize efficiency and size.
Who should skip it
You should look elsewhere if you need a standard ATX power supply. This unit is SFX and will not fit in cases designed for larger PSUs. The 750 watt limit may be insufficient for high-end gaming rigs with top-tier graphics cards. You might need more headroom for future upgrades. If you prefer a non-modular design for simplicity, this fully modular unit adds complexity. It is also only available in black. If you need a white unit or higher wattage, this model does not fit your needs.

Key specs for Lian Li SP 750W
Wattage: 750 WATT
This power supply delivers 750 watts of continuous power. You need this capacity to run high-end graphics cards and modern processors without strain. If your system draws more than this limit, the unit may shut down. Compare this value against your CPU and GPU power requirements to ensure you have enough headroom for upgrades or peak loads during gaming.
Efficiency Rating: 80 Plus Gold
The 80 Plus Gold rating means the unit converts at least 90% of AC power to DC power at typical loads. You save on electricity bills and generate less waste heat. This is better than Bronze or Silver rated units. When shopping, look for Gold ratings if you want better efficiency and quieter operation compared to lower-tier certified power supplies.
Modularity: Fully Modular
Fully modular means you connect only the cables you actually use. This reduces clutter inside your case and improves airflow. You do not need to bundle unused cables that block fans. This feature is essential for small cases where space is tight. Compare this with non-modular units where all cables are fixed, which can make cable management difficult in compact builds.
Form Factor: SFX
The SFX form factor is a small physical size designed for compact PC cases. You can fit this unit into cases that do not support standard ATX power supplies. It measures 125mm by 86mm. When building a small form factor PC, check your case compatibility first. Standard ATX units will not fit in these tighter spaces, making SFX a necessary choice.
Design and build specs
According to the listing, the Lian Li SP 750W Gold SFX measures 10 inches in length, 8 inches in width, and 5 inches in height. These dimensions align with the standard SFX form factor. You should verify your case supports this size before purchase. The compact chassis allows installation in smaller builds where space is limited. The unit is finished in black. This color choice helps it blend into most modern PC cases without drawing attention.
The power supply is fully modular. This means you can connect only the cables you need. You leave unused cables disconnected and stored elsewhere. This approach reduces clutter inside your case. It also improves airflow by removing unnecessary wires from the main compartment. Better airflow helps keep your components cool during heavy workloads.
The listing does not mention the weight. It also does not describe the internal materials or fan type. You rely on the published specifications for these details. The 80 Plus Gold rating indicates high efficiency. This means less wasted energy as heat. You benefit from lower electricity usage and potentially quieter operation. The black finish and modular design prioritize a clean look and organized cable management in tight spaces.
Setup and everyday use
Installing this unit requires attention to its compact SFX dimensions. The listing specifies a width of eight inches, a height of five inches, and a length of ten inches. You must ensure your case accommodates these exact measurements. Standard SFX mounting holes align with this form factor, but smaller cases may have clearance issues for cables or the unit itself.
The fully modular design simplifies the installation process. You only connect the cables your system actually needs. This reduces clutter inside the chassis, which is critical in small form factor builds where airflow can be restricted. Black cables help them blend into the interior, maintaining a clean aesthetic. You manage cable routing carefully to avoid obstructing fans or other components.
In daily operation, the 80 Plus Gold rating indicates high efficiency under typical loads. This means less wasted energy as heat, which can lower internal temperatures. The 750-watt output provides ample headroom for modern CPUs and graphics cards. You do not need to worry about power shortages during standard gaming or productivity tasks. The unit operates quietly because it does not need to work hard to maintain efficiency. This contributes to a stable and silent computing environment. The black color scheme remains consistent with the exterior finish, ensuring it looks uniform whether visible or hidden.
Before you buy this PSU
You should verify case compatibility before purchasing. This unit follows the standard SFX dimensions. Your chassis must support this specific form factor. You need enough internal space for the ten-inch length. Check cable management routes in your case. Fully modular design helps reduce clutter. You connect only the cables you use. This keeps airflow clear in tight builds. Ensure your motherboard has the required connectors. High-end GPUs need proper power delivery. This 750-watt output suits most modern systems. The 80 Plus Gold rating saves energy. It runs cooler under load. You benefit from lower electricity costs over time. Consider this option if space is limited. It fits alongside other SFX units on the page. Compare its wattage against larger ATX models. SFX units often cost more per watt. You pay for compactness and efficiency. This model offers a balanced spec sheet. It suits builders who prioritize size and power.
Check before you buy
- Confirm your case supports SFX form factor
- Check internal length clearance for ten inches
- Verify GPU power connector requirements
- Ensure motherboard has necessary PCIe cables
