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.

Questions about this item

Will this 150 mm long unit fit in a standard ATX case?

The power supply is 150 mm long, so it fits most mid-tower cases that accept standard ATX units; check your case clearance before buying.

Does the single +12 V rail deliver the full 1000 W to modern GPUs?

Yes, the single-rail design provides the entire 1000 W on the +12 V line, supporting PCIe 5.1 graphics cards and high-end SLI or CrossFire setups.

What cables come in the box and are they all detachable?

The unit is fully modular with braided cables, including a 20+4 pin motherboard connector and enough PCIe leads for multi-GPU builds; only the cables you need are installed.
