SP750 vs SP 750 GA Specs
efficiency rating
Both the Lian Li 750W SFX Gold Power Supply and the Lian Li SP 750W Gold SFX carry the 80 PLUS Gold certification. This rating means each unit converts at least 90% of AC power to DC output at typical loads. You get lower heat generation and reduced energy waste compared to standard Bronze units. Since both models share this exact efficiency tier, neither offers a technical advantage here. Your choice will not be influenced by power conversion performance.
modularity
Each power supply is fully modular. This means you can detach every cable from the unit itself. You only plug in the cables you actually need for your specific build. This reduces clutter inside your case and improves airflow. Since both the Lian Li 750W SFX Gold Power Supply and the Lian Li SP 750W Gold SFX offer full modularity, there is no difference in cable management flexibility. Both provide the same clean installation experience.
form factor
Both units are listed as SFX form factor. This compact size is designed for small form factor cases where standard ATX or ATX SFX units will not fit. However, the physical dimensions listed for the Lian Li SP 750W Gold SFX are 8 inches by 5 inches by 10 inches. This exceeds the standard SFX footprint of 3 inches by 5 inches by 4 inches. The Lian Li 750W SFX Gold Power Supply matches the standard 3x5x4 size. You should verify your case compatibility with the larger unit.
physical dimensions
The Lian Li 750W SFX Gold Power Supply measures 3 inches by 5 inches by 4 inches. This is the standard SFX size. The Lian Li SP 750W Gold SFX lists dimensions of 8 inches by 5 inches by 10 inches. This is significantly larger in length and width. If you are building in a tight chassis, the standard SFX size of the first unit is safer. The second unit may require a larger case or specific mounting considerations due to its non-standard dimensions.
model designation
The first unit is the SP750. The second unit is the SP 750 GA. The GA suffix often indicates a specific revision or regional variant. The data shows the SP 750 GA model also has a color attribute of black, despite the model name including white. This suggests the color may vary or the listing is inconsistent. You should check the actual product images to confirm the cable and chassis color before purchasing, as the model names do not clearly indicate the final appearance.
Which Lian Li PSU fits your build
Small form factor builders needing compact size
The SP750 measures 3 by 5 by 4 inches. This compact footprint fits inside tight cases where space is limited. You get the same 750W output and 80 PLUS Gold efficiency as the larger unit. Choose this model if your chassis requires a smaller physical power supply without sacrificing modular cable management or high efficiency ratings.
Users prioritizing standard SFX dimensions
The SP 750 GA lists dimensions of 8 by 5 by 10 inches. While the attributes label it as SFX, the listed width and length are significantly larger than the SP750. If your case accommodates these larger physical dimensions, this unit provides the same 750W capacity and fully modular cabling. Verify your case compatibility with these specific measurements before purchasing.
Enthusiasts wanting verified compact SFX specs
The SP750 adheres to standard SFX physical constraints with its 3 by 5 by 4 inch size. This ensures it fits in most mini-ITX and small form factor builds designed for standard SFX units. You retain the benefits of 80 PLUS Gold efficiency and fully modular cables. Select this unit to ensure physical compatibility with your compact computer chassis.
