What this PSU is and who it is for

The Super Flower Leadex III GE delivers 1300 W of continuous power in a fully modular ATX 3.1 design. It targets builders who need headroom for multi-GPU workstations or high-end gaming rigs and want every cable detachable for clean routing. The single +12 V rail simplifies load balancing across demanding components.

Practical limits of the ATX 3.1 interface

ATX 3.1 and PCIe 5.1 compliance mean the unit can absorb transient spikes without tripping protections. The 150 mm depth fits most mid-tower and full-tower cases, but compact chassis may require a measurement check. Efficiency peaks at 90 % under typical loads, with 87 % at both 20 % and 100 % load points. Input covers 100 to 240 V at 50 or 60 Hz.

Build quality and daily connector implications

A 140 mm fluid dynamic bearing fan with a copper shaft runs semi-fanless at low loads, reducing idle noise. Full modular ribbon cables include one native 12V-2x6, four 8-pin PCIe, two 8-pin EPS, nine SATA and four peripheral plugs. Protections cover OVP, OCP, OPP, SCP, UVP, OTP, NLO and SIP. Cybenetics Platinum and 80 PLUS Gold certifications back the efficiency claims.

Questions about this item

Which modular cable set should I choose for a build that needs two CPU power connectors and four PCIe connectors?

The unit includes two 8-pin (4+4) EPS cables for CPU power and four 8-pin (6+2) PCIe cables for graphics cards, all detachable thanks to the full-modular design.

What does the 1300 W rating mean when the supply is running inside a closed case?

The 1300 W maximum is continuous output at up to 50 °C ambient, delivered on a single +12 V rail with 87 % efficiency at full load and 90 % at half load.

How does the ATX 3.1 and PCIe 5.1 compliance cap the power spikes a modern GPU can draw?

The native 12V-2x6 connector and ATX 3.1 design are rated for 2× transient spikes, meeting the PCIe 5.1 specification for short-duration power excursions.
