Super Flower Leadex 2800W ATX 3.1 power supply review: Top-notch build quality, exceptional efficiency
The Super Flower Leadex 2800W is currently the most powerful retail power supply unit available, boasting exceptional efficiency and build quality. Designed for high-demand workstation and gaming setups, it requires a specific voltage input for optimal performance. While it offers premium components and features, its high price and loud operation at load may deter some potential buyers.
- ▪The Leadex 2800W is rated for 2800 watts continuous output and carries a Cybenetics Titanium certification.
- ▪It requires a 200 to 240 VAC input for maximum power, limiting its usability on standard North American outlets.
- ▪The unit is designed for extreme gaming and workstation builds, not typical desktop use.
