Super Flower Leadex III Gold 1000W 80 Plus Black/White Power Supply

The Super Flower Leadex III Gold 1000W is a premium fully-modular ATX 3.1 power supply built for high-end and enthusiast PCs. It combines 80 PLUS Gold and Cybenetics Gold efficiency, a strong single +12V rail, a native 12V-2×6 GPU cable, 100% Japanese capacitors, and a whisper-quiet 140mm fluid-dynamic-bearing fan with Zero-RPM mode — delivering clean, stable, efficient power with plenty of headroom for the most demanding builds.

1. 80 PLUS Gold & Cybenetics Gold Efficiency

The Leadex III Gold 1000W is dual-certified — 80 PLUS Gold and Cybenetics Gold — running at roughly 87% / 90% / 87% efficiency at 20% / 50% / 100% load. Higher efficiency means more of the power drawn from the wall reaches your components and less is wasted as heat, so you get a cooler, quieter system and lower running costs over the life of the unit.

• 80 PLUS Gold and Cybenetics Gold certified
• Approx. 87% / 90% / 87% efficiency across the load range
• Less wasted heat for cooler, quieter operation

2. ATX 3.1 with a Native 12V-2×6 GPU Cable

Built to the latest ATX 3.1 and EPS 12V v2.92 standards, the Leadex III Gold 1000W is designed to handle the transient power spikes of modern graphics cards. It includes a native 12V-2×6 (12+4 pin) GPU cable — a single, direct cable to your current-generation GPU with no adapter required — for the cleanest, most reliable connection.

• ATX 3.1 & PCIe 5.1 compliant design
• Native 12V-2×6 (12+4 pin) GPU cable included — no adapter needed
• Handles modern GPU power transients

3. Fully Modular with Ultra-Flexible Ribbon Cables

Every cable is fully modular, so you connect only the cables your build actually needs — less clutter, better airflow, and a cleaner install. The Leadex III Gold uses ultra-flexible flat ribbon cables that route easily behind the motherboard tray and bend neatly around tight corners, making cable management genuinely easy.

• Fully modular — attach only the cables you need
• Ultra-flexible flat ribbon cables for easy routing
• Four PCI-E 6+2 pin connectors plus the native 12V-2×6 cable

4. Strong Single +12V Rail

The +12V rail powers your GPU and CPU, and the Leadex III Gold 1000W puts almost all of its capacity there — delivering up to 83.3A on a single +12V rail (999.6W). A single high-current rail keeps power delivery simple and stable under heavy gaming and rendering loads, with ample headroom for high-end graphics cards.

• Single +12V rail rated up to 83.3A (999.6W)
• Ample headroom for high-end and enthusiast GPUs
• Stable voltage under sustained load

5. Quiet 140mm FDB Fan with Zero-RPM ECO Mode

A 140mm Ultra-Silent Fluid Dynamic Bearing fan keeps the unit cool and quiet, and its Zero-RPM ECO mode stops the fan entirely at low and medium loads — so the power supply is completely silent during light tasks like browsing or office work, and only spins up when it’s actually needed.

• 140mm Fluid Dynamic Bearing fan for quiet, long-life cooling
• Zero-RPM ECO mode — silent under light loads
• Passed 50°C hot-box testing for reliability under heat

6. 100% Japanese Capacitors & Full Protection

The main board uses 100% Japanese 105°C capacitors for long-term reliability under heat — a hallmark of quality in premium power supplies. A comprehensive protection suite — OVP, OCP, OPP, SCP, UVP, OTP and SIP — guards your components against over-voltage, over-current, over-power, short circuits, under-voltage, over-temperature and surge/inrush conditions.

• 100% Japanese 105°C main-board capacitors
• Full protection: OVP / OCP / OPP / SCP / UVP / OTP / SIP
• Lead-free, RoHS / WEEE compliant materials

7. Broad Compatibility & Full-Range Input

With a Full-Range Active PFC design and 100V~240V auto voltage detection, the Leadex III Gold 1000W works reliably on any mains supply. It supports all Intel and AMD multi-core CPUs on ATX / BTX motherboards and is Modern Standby compatible for fast, low-power wake behaviour.

• Full-range 100V~240V auto voltage detection (Active PFC)
• Supports Intel & AMD multi-core CPUs on ATX / BTX boards
• Modern Standby compatible

Frequently Asked Questions

Does the Leadex III Gold 1000W include a native 12V-2×6 cable?
Yes — it ships with a native 12V-2×6 (12+4 pin) GPU cable, so you can connect a current-generation graphics card directly without an adapter.

Is it fully modular?
Yes. Every cable detaches, so you only install the ones your build needs, using ultra-flexible flat ribbon cables.

Is the fan always on?
No. The 140mm FDB fan has a Zero-RPM ECO mode that keeps it completely stopped under light and medium loads, so the unit runs silently until higher loads require cooling.

What efficiency rating does it have?
It is both 80 PLUS Gold and Cybenetics Gold certified, running at approximately 87% / 90% / 87% efficiency at 20% / 50% / 100% load.
