Our top pick: Lian Li SP 750W Gold SFX Power Supply.
How the alternatives compare
SilverStone 700W SFX 80 Plus Gold Power Supply
The SilverStone 700W SFX offers 80 Plus Gold efficiency and full modularity, similar to the Lian Li SP 750W. However, it provides 50 fewer watts of output. Its physical dimensions are notably smaller, measuring 3.94 by 2.5 by 4.92 inches compared to the Lian Li’s 8 by 5 by 10 inches. This makes it a better fit for extremely tight chassis where space is the primary constraint. You should choose this unit if you need a smaller footprint and can accept slightly lower wattage for your build.
Thermaltake Toughpower iRGB Plus 750W Gold PSU
The Thermaltake Toughpower iRGB Plus 750W matches the Lian Li’s 750W output and 80 Plus Gold efficiency rating. It differs significantly in form factor, using standard ATX dimensions of 5.9 by 3.4 by 6.3 inches rather than the compact SFX size. This unit includes customizable RGB lighting, which the Lian Li lacks. It also carries a 10-year warranty. You should pick this alternative if you are building in a standard ATX case and want aesthetic customization and a longer warranty period instead of compact sizing.
EVGA SuperNOVA GA 650W Power Supply
The EVGA SuperNOVA GA 650W provides 80 Plus Gold efficiency and full modularity, aligning with the Lian Li’s core features. It delivers 100 fewer watts, outputting 650W instead of 750W. Its ATX form factor is much larger, measuring 9 by 4.8 by 11.8 inches. Like the Thermaltake, it includes a 10-year warranty. This option suits builders who do not need the full 750W capacity and prioritize a long warranty and efficient operation in a standard desktop case over the compact SFX dimensions of the original.
EVGA SuperNOVA 850 GM SFX Power Supply
The EVGA SuperNOVA 850 GM SFX shares the same compact SFX form factor and 80 Plus Gold efficiency as the Lian Li SP 750W. It distinguishes itself by offering 850W of power, which is 100W more than the Lian Li unit. It also includes a 10-year warranty. This unit is ideal if you require higher wattage headroom for demanding components while still needing to fit into a small form factor chassis. It provides more power and a longer warranty without changing the physical size constraints.
GAMEMAX 1050W ARGB Fully Modular PSU
The GAMEMAX 1050W ARGB PSU is designed for standard ATX cases, not compact SFX builds. It offers significantly higher power at 1050W with 80 Plus Gold efficiency and ATX 3.0 compliance. It features ARGB lighting, which the Lian Li does not. Its dimensions are 5.91 by 3.35 by 6.61 inches, making it incompatible with small form factor cases. You should select this alternative if you are building a high-performance gaming PC in a standard tower and need modern GPU connectors and higher wattage than the SFX options provide.
Lian Li 750W SFX Gold Power Supply
The Lian Li 750W SFX Gold is another option from the same brand, offering identical 750W output and 80 Plus Gold efficiency. It is fully modular like the original. The key difference is its physical size, measuring 3 by 5 by 4 inches, which is smaller than the SP 750W’s 8 by 5 by 10 inches. This makes it a more space-efficient choice for tight builds. You should consider this unit if you want the same brand reliability and power output but need a more compact footprint to fit your specific chassis.
