Lian Li 750W SFX Gold Power Alternatives: 6 Similar Picks Compared

How these units differ from Lian Li

SilverStone 700W SFX 80 Plus Gold Power Supply

The SilverStone SST-SX700-G offers 700W in a significantly smaller physical footprint than the Lian Li SP 750. Its dimensions are 3.94 by 2.5 by 4.92 inches, making it much more compact for tight chassis. It maintains 80 PLUS Gold efficiency and fully modular cabling like the original. However, you lose 50W of total power output. This unit weighs 3.09 pounds, which is heavier than the Lian Li option. It is ideal for builders who prioritize minimal size over maximum wattage while still requiring silent, efficient operation in small form factor builds.

Lian Li SP 750W Gold SFX Power Supply

This Lian Li SP 750 Gold variant shares the 750W output and 80 PLUS Gold efficiency rating with the original model. It is fully modular, ensuring clean cable management. The physical dimensions are listed as 8 by 5 by 10 inches, which differs from the standard SFX measurements of the reference unit. It is designed for compact builds where efficiency and modularity are the primary concerns. The black color matches the original aesthetic. You get the same reliable performance in a slightly different package. This pick suits users who want the Lian Li brand reliability and high efficiency in a small form factor without needing the specific dimensions of the first model.

ASUS ROG Loki SFX-L 750W Platinum

The ASUS ROG Loki SFX-L provides 750W with 80 PLUS Platinum efficiency, surpassing the Gold rating of the Lian Li SP 750. It supports ATX 3.0 standards, offering modern connectivity for newer graphics cards. The form factor is SFX, fitting similar small cases. Its dimensions are 4.9 by 2.5 by 4.9 inches, which is a different shape than the original. It weighs 4 pounds. This unit is best for builders who need high efficiency and current generation power connectors. It gives up the specific zero-RPM silent mode feature found in the Lian Li unit but delivers superior efficiency and modern compatibility for compact gaming rigs.

EVGA SuperNOVA 750W Bronze Power Supply

The EVGA SuperNOVA 750W Bronze is an ATX unit, not an SFX power supply. It measures 5.9 by 3.4 by 7.1 inches and weighs 7 pounds. This makes it unsuitable for small form factor cases that require SFX dimensions. It offers 750W of power but with 80 PLUS Bronze efficiency, which is lower than the Gold rating of the Lian Li SP 750. It is designed for standard desktop towers. You should pick this alternative if you are building in a standard ATX case and need reliable power. It does not fit the compact requirements of the original product but serves as a solid option for larger chassis.

FSP 300W Flex ATX Power Supply

The FSP 300W Mini ITX Gold is a very low-power unit compared to the 750W Lian Li SP 750. It offers 80 PLUS Gold efficiency in a tiny 3.2 by 1.6 by 5.9 inch package. It weighs only 1.8 pounds. This form factor is distinct from SFX and is intended for Mini ITX builds with minimal power needs. You give up significant wattage here, as 300W is far below the 750W requirement. This unit is best for users building low-power systems where space is extremely limited and high efficiency is critical. It is not a direct alternative for high-performance builds requiring the power of the original Lian Li unit.

EVGA 500 BQ 500W Semi-Modular Power Supply

The EVGA 500 BQ is a 500W semi-modular power supply with 80 PLUS Bronze efficiency. It uses standard ATX dimensions of 5.91 by 3.35 by 5.51 inches. This makes it incompatible with SFX form factor cases. It weighs 1.1 pounds. You lose both the higher wattage and the Gold efficiency rating compared to the Lian Li SP 750. The semi-modular design means some cables are fixed. This unit is suitable for standard ATX desktop builds needing moderate power. It is not a viable alternative for small form factor builds that require the compact size and high efficiency of the original SFX unit.
