ATX 3.1 Platinum Power Supply

This Super Flower Leadex III unit delivers 1000 W of continuous power and meets the ATX 3.1 and PCIe 5.1 specifications. A Cybenetics Platinum rating confirms efficiency above 90 % across typical loads. The fully modular design uses braided cables for cleaner routing. A 140 mm fluid-dynamic-bearing fan runs in a semi-fanless ECO mode at low load.

High-end build suitability

The 150 mm depth fits most mid-tower and larger cases, while the single +12 V rail simplifies power distribution for multi-GPU configurations. Builders needing a shorter chassis depth or a lower wattage for compact systems should consider other models. SLI and CrossFire readiness supports legacy dual-GPU setups.

ATX 3.1 and PCIe 5.1 compliance

Compliance with the ATX 3.1 standard and PCIe 5.1 readiness means the unit handles the transient power spikes demanded by modern graphics cards. This specification is the primary factor in deciding whether the power supply matches your hardware requirements.
