Super Flower Leadex III Gold 1000W Fully Modular PSU

Super Flower Leadex III Gold 1000W Fully Modular PSU

ATX 3.1 & PCIe 5.1 Future-Proofing: Designed to meet the absolute latest Intel ATX 3.1 specifications, the Leadex III 1000W safely mitigates the massive transient power spikes commonly generated by modern flagship graphics cards. Furthermore, Super Flower has completely engineered around the infamous 12VHPWR cable bending issue. Instead of using a fragile 16-pin connector on the power supply itself, this unit features robust dual 8-pin sockets that merge into a native 12+4 pin connector on the GPU side, delivering extremely clean, high-wattage power without the risk of terminal melting.

Premium Efficiency and Build Quality: While it easily clears the 80 PLUS Gold standard, independent testing by Cybenetics has awarded this unit a prestigious Platinum efficiency rating, ensuring minimal energy waste and reduced heat output. Internally, the Leadex III relies on a top-tier Japanese main capacitor known for exceptional reliability, heat tolerance, and delivering tight voltage regulation with extremely low ripple noise.

Intelligent, Silent Cooling: To keep the internals frosty, Super Flower equipped the Leadex III with a premium 140mm Fluid Dynamic Bearing (FDB) fan built with a copper shaft for long-lasting durability. Thanks to the built-in ECO thermal control system, the fan remains completely stationary during light to medium workloads, providing a perfectly silent 0dB experience. When you launch a heavy game or rendering task, the fan intelligently spins up to maintain optimal temperatures. All of this power is routed through ultra-flexible, flat ribbon cables, making neat cable management effortless.

Key Features

• 1000W Continuous Output: Perfect for powering modern high-end builds featuring CPUs like the Intel Core i7/i9 or Ryzen 7/9 alongside an RTX 4080 or 4090.
• ATX 3.1 & PCIe 5.1 Certified: Built to withstand the massive 200% power excursions of next-generation hardware.
• Safer 16-Pin Cable Design: Employs dual 8-pin connectors on the PSU side that combine into the 12+4 pin GPU connector to prevent high-angle bending failures.
• ECO Fan Mode: The 140mm FDB fan remains completely off during low loads for a dead-silent desktop experience.
• Premium Japanese Main Capacitor: Ensures long-term durability and clean, ripple-free power delivery to your expensive components.
• Fully Modular Ribbon Cables: Thin, flexible flat cables allow for easy routing and a clean internal aesthetic.

Who It’s For

• High-End Gamers: Perfect for builders running powerful combinations like an RTX 4080 Super or RX 7900 XTX who want massive headroom and absolute stability.
• Silent PC Enthusiasts: Users who want a completely quiet system while browsing or watching videos, as the ECO mode ensures the fan stays off until the system is heavily loaded.
• Safety-Conscious Upgraders: PC builders who are nervous about the melting 12VHPWR cables on other PSUs will love Super Flower’s proprietary dual 8-pin to 16-pin cable design.

Frequently Asked Questions

1. Will this 1000W power supply fit in my mid-tower case? Yes. Measuring just 150mm in length, the Leadex III 1000W is surprisingly compact for its massive wattage. It will easily fit into standard ATX mid-tower cases without requiring you to remove hard drive cages or struggle with cable routing in the basement of your case.
2. Why are there dual 8-pin connections on the power supply for the new 16-pin GPU cable? Super Flower intentionally designed it this way for safety. The new 12V-2×6 (16-pin) socket is prone to overheating if the cable is bent too sharply near the connector. By using two standard, highly durable 8-pin sockets on the power supply itself and merging them into the 16-pin connector at the GPU end, it eliminates the risk of the cable melting at the power supply housing while still fully complying with ATX 3.1 standards.
3. Does it come with cables for older graphics cards? Yes. While it includes the new 16-pin cable for modern RTX 40-series and 50-series cards, it also comes with four standard 6+2 pin PCIe cables, ensuring full compatibility with older NVIDIA and AMD graphics cards.
