1000W ATX 3.1 power supply

The Super Flower Leadex VII XG delivers 1000W through a single +12V rail with full modular cabling. It meets ATX 3.1 and PCIe 5.1 specifications and includes a native 12VHPWR cable built from two 8-pin connectors. A 140mm fluid dynamic bearing fan provides cooling while maintaining Cybenetics Standard++ noise performance.

Builders seeking high efficiency

This unit suits systems that require ATX 3.1 compliance and a native 12VHPWR connection for current graphics cards. The white finish and ribbon-style modular cables help with cable routing in showcase builds. Users needing a smaller form factor or a lower wattage unit should consider other models.

1000W capacity with Gold and Platinum ratings

The power supply achieves 87% efficiency at 20% load, 90% at 50% load and 87% at 100% load under the 80 PLUS Gold programme. Cybenetics Platinum certification confirms 89% to 91% overall efficiency at 115V input and 91% to 93% at 230V input. Twelve SATA power connectors support multiple drives, while the 150mm depth fits most standard ATX cases.

Questions about this item

Does my motherboard need an ATX 3.1‑compatible 20+4‑pin socket to use this 1000 W unit?

The PSU provides a standard 20+4‑pin main connector; it will seat in any ATX motherboard socket, but ATX 3.1 features require a board that implements that specification.

Can I keep my existing SATA drives and power them from the modular cables?

Yes, twelve SATA power connectors are supplied on the modular ribbon cables, so current SATA SSDs or hard drives plug in directly.

How do I confirm the fan is running in its low‑noise mode after installation?

The 140 mm fluid‑dynamic‑bearing fan meets Cybenetics Standard ++; listen for a quiet, steady airflow — no rattling or speed surges — once the system is under load.
