Leadex VII vs Combat SFX Comparison
wattage output
The Super Flower Leadex VII XG 1000W delivers 1000W of continuous power. This higher output suits high-end builds with multiple GPUs or extreme overclocking. The Super Flower Combat SFX FP 850W provides 850W. This is sufficient for most modern single-GPU systems. You choose the Leadex for raw power headroom. You choose the Combat SFX for compact efficiency. The 150W difference matters only if your components demand it. Check your GPU and CPU TDPs before deciding which limit fits your build.
form factor
The Leadex VII XG 1000W uses the standard ATX form factor. Its dimensions are 5.9 by 3.4 by 5.9 inches. This fits most mid-tower and full-tower cases. The Combat SFX FP 850W uses the SFX form factor. Its dimensions are 3.93 by 2.5 by 4.92 inches. This small size is ideal for Small Form Factor (SFF) cases. SFF cases have limited space for standard ATX units. If you have a compact case, the Combat SFX is your only option. For standard cases, both fit, but the ATX unit offers more physical space for components.
efficiency rating
Both power supplies achieve Cybenetics Platinum certification. This indicates excellent efficiency across load ranges. The Leadex VII XG 1000W also holds an 80 PLUS Gold certification. It reports 87% efficiency at 20% load, 90% at 50% load, and 87% at 100% load. The Combat SFX FP 850W lists Cybenetics Platinum but does not specify 80 PLUS Gold in its key specs. Both units are highly efficient. The Leadex has the additional 80 PLUS Gold badge. This may matter for strict energy auditing. For daily use, both minimize power waste effectively.
voltage regulation
The Leadex VII XG 1000W specifies tight voltage regulation. It maintains ±0.5% stability on the 12V, 5V, and 3.3V rails. This precision helps protect sensitive components from power fluctuations. The Combat SFX FP 850W data does not list specific voltage regulation percentages. It does mention Full Range Auto Voltage Detection for 100V to 240V input. This ensures compatibility with global power grids. Without explicit rail stability numbers, you cannot compare precision directly. The Leadex provides verified tight regulation data for peace of mind.
atx and pcie version
Both units support ATX 3.1 and PCIe 5.1 standards. They include the 12V-2x6 connector for modern graphics cards. This connector handles transient power spikes from new GPUs. The Leadex VII XG 1000W also cites Intel ATX 3.0 certification alongside ATX 3.1. The Combat SFX FP 850W lists compliance with ATX 3.1. Both are ready for the latest hardware. The Leadex has the dual certification mention. This does not change functionality. Both units support the latest PCIe 5.1 power requirements for NVIDIA and AMD GPUs.
modularity
Both power supplies feature full modular designs. You can connect only the cables you need. This reduces clutter inside your case. Both units come with all ribbon cables. Ribbon cables are flat and flexible. They are easier to route in tight spaces than round cables. This improves airflow and aesthetics. The Leadex VII XG 1000W and Combat SFX FP 850W offer identical cabling approaches. You get the same flexibility and cable management benefits from both. This is a shared strength, not a differentiator.

Frequently asked questions
Which Super Flower PSU fits in a small ITX case?
The Super Flower Combat SFX FP 850W is the correct choice for compact builds. It uses a smaller SFX form factor with dimensions of 4.92 by 2.5 by 3.93 inches. This allows it to fit into cases that cannot accommodate standard ATX units. The Leadex VII XG 1000W is larger and requires more space.
Does the Leadex VII XG support the latest PCIe 5.1 standard?
Yes, the Super Flower Leadex VII XG 1000W supports PCIe 5.1. It also complies with the ATX 3.1 specification. This ensures compatibility with modern graphics cards that require high power delivery. You can connect new GPUs directly without needing adapters for standard PCIe power.
What is the weight difference between these two power supplies?
The Leadex VII XG 1000W weighs 4.5 pounds. The Combat SFX FP 850W is lighter at 3.7 pounds. The extra weight in the Leadex unit comes from its larger ATX chassis and higher 1000W capacity. The lighter SFX unit is better for builds where weight distribution matters.
Can the Combat SFX FP 850W handle a high-end GPU?
Yes, the Super Flower Combat SFX FP 850W supports PCIe 5.1. This allows it to power modern high-end graphics cards efficiently. While it provides 850W instead of 1000W, it is sufficient for most single-GPU builds. It prioritizes compact size without sacrificing modern connectivity standards.
Which unit is better for a standard ATX mid-tower case?
The Leadex VII XG 1000W is better for standard ATX cases. It uses the full ATX form factor, which fits easily into most mid-tower and full-tower chassis. Its 1000W output provides extra headroom for high-power components. The smaller SFX unit is unnecessary unless you are building in a compact case.
Are both power supplies fully modular?
Yes, both units are fully modular. This means you can connect only the cables you need. This feature helps with cable management and airflow inside your case. Both the Leadex VII XG and Combat SFX FP share this design trait, allowing for cleaner builds regardless of the form factor you choose.
