Super Flower Leadex VII XG 850W (850W/80+ Gold/Fully Modular/ATX 3.0/High-End Tier) Review
Enthusiasts hunting for a power supply that tests better than its 80 PLUS badge suggests will find the Super Flower Leadex VII XG 850W a familiar name: Super Flower units routinely measure closer to Platinum or Titanium efficiency despite carrying a Gold certification.
We'd recommend this to anyone who reads independent PSU reviews before buying, since Super Flower's reputation is built on exactly that kind of over-delivery. The 12-year warranty and full Japanese capacitor set are rare at this price, even if the Leadex VII name isn't as widely recognized as Corsair or Seasonic.
Over-Delivering on Its Rating
Super Flower has a well-earned reputation among independent reviewers for units that measure meaningfully better than their 80 PLUS certification, and the Leadex VII XG's Cybenetics Platinum result on a Gold-badged unit is typical of the brand.
Comparison to Alternatives
Against the ASUS ROG Strix 850W Gold ATX3.0 already in the catalog, the Leadex VII XG matches the wattage and ATX 3.0 native connector while adding a longer 12-year warranty and full Japanese capacitors. Against the Antec HCG850 Gold Extreme, the Leadex VII XG edges ahead on measured efficiency and capacitor quality at a similar price.
