Leadex VII vs Combat SFX Specs
Wattage output
The Super Flower Leadex VII XP PRO delivers 1000W of power, while the Super Flower Combat SFX FP offers 850W. If your build requires higher sustained power for multiple GPUs or heavy overclocking, the Leadex provides that extra headroom. The Combat SFX is sufficient for high-end single-GPU systems but has a lower ceiling. Choose the Leadex for maximum power capacity and the Combat for standard high-performance needs.
Form factor size
Size is the primary differentiator here. The Leadex VII XP PRO is a standard ATX unit measuring 5.9 x 3.4 x 5.9 inches. It fits most standard mid-tower and full-tower cases. The Combat SFX FP is a compact SFX unit at 3.93 x 2.5 x 4.92 inches. It is designed specifically for Small Form Factor (SFF) builds where space is tight. You must choose the Combat if you are building in a mini-ITX case.
Efficiency certification
Both units achieve Cybenetics Platinum certification, indicating excellent energy efficiency. The Leadex VII XP PRO also holds an 80 PLUS Platinum rating, listing specific efficiency percentages at various loads: 90% at 20% load, 92% at 50% load, and 89% at 100% load. The Combat SFX FP lists only the Cybenetics Platinum badge without detailed load percentages in the provided data. Both are highly efficient, but the Leadex provides more granular efficiency data.
Voltage regulation
The Leadex VII XP PRO specifies tight voltage regulation of ± 0.5% for the 12V, 5V, and 3.3V rails. This precision ensures stable power delivery to sensitive components. The Combat SFX FP data does not list specific voltage regulation tolerances. While both are from Super Flower, the Leadex explicitly guarantees tighter variance. This makes the Leadex the better choice if you require verified, tight voltage stability for your components.
Weight and build
The Leadex VII XP PRO weighs 4.5 pounds, reflecting its larger ATX chassis and internal components. The Combat SFX FP is lighter at 3.7 pounds due to its compact SFX design. Weight often correlates with component quality and heat dissipation capacity. The Leadex is heavier, which may aid in thermal management for higher wattages. The Combat is lighter, aiding portability and fitting into smaller enclosures. Your case constraints dictate the weight preference.
Standby compatibility
The Combat SFX FP explicitly lists Modern Standby compatibility. This feature ensures the power supply works correctly with newer sleep states in Windows and other operating systems. The Leadex VII XP PRO data does not mention Modern Standby support. If your system relies on Modern Standby features, the Combat SFX FP is the safer choice. Otherwise, this feature is less critical for traditional sleep modes.
Which Super Flower Power Supply Fits You
Users building in small form factor cases
The Combat SFX FP measures 3.93 by 2.5 by 4.92 inches. This compact SFX form factor fits tight chassis where standard ATX units will not. You get full modularity and ribbon cables in a small footprint. The 850W output supports modern GPUs while saving space inside your case.
Users needing maximum power for high end builds
The Leadex VII XP PRO delivers 1000W of power. This higher wattage provides headroom for heavy overclocking or multiple graphics cards. It maintains tight voltage regulation across all rails. You get full modularity with ribbon cables to keep your build clean and organized.
Users prioritizing certified efficiency ratings
The Leadex VII XP PRO holds both 80 PLUS Platinum and Cybenetics Platinum certifications. This dual certification confirms high efficiency at various load levels. You benefit from reduced heat output and lower power consumption. The Combat SFX FP only lists Cybenetics Platinum certification.
Users requiring modern standby compatibility
The Combat SFX FP explicitly supports Modern Standby. This ensures your system can enter low power states correctly for quick wake times. You also get active PFC with full range auto voltage detection. This feature adapts to input voltages from 100V to 240V.
