1000 W ATX 3.0 3.1 power supply

This 1000 W unit meets ATX 3.0 and ATX 3.1 specifications for modern desktop builds. It targets system integrators and enthusiasts who need a single 12 V rail and full modular cabling. The 80 PLUS Gold rating confirms up to 92 % efficiency at typical loads. It is built for high-end graphics cards and multi-GPU configurations.

Full modular design with Japanese capacitors

A fully modular layout lets builders connect only the cables required, reducing clutter and improving airflow. All electrolytic capacitors are sourced from Japanese manufacturers for long-term reliability. The 120 mm fluid dynamic bearing fan runs quietly and stops completely under light loads via ECO mode. The compact 140 mm depth fits most standard chassis.

Native 600 W 12V-2x6 connector for GPU upgrades

One native 12+4 pin 12V-2x6 cable delivers up to 600 W to PCIe 5.0 graphics cards without adapters. Four additional 6+2 pin PCIe connectors support multi-GPU SLI or CrossFire setups. The platform handles 235 % total power excursion and 300 % GPU power excursion for transient spikes. This unit replaces older supplies that lack the 12V-2x6 interface or sufficient excursion headroom.

Perguntas sobre este artigo

Will the 1000 W unit and its 140 mm length fit my mid-tower case?

The power supply is 140 mm long, so it fits most mid-tower cases that accept standard ATX units; measure your case clearance to confirm.

Can I run a modern GPU that needs the 12V-2x6 connector without adapters?

Yes, a native 600 W 12+4-pin 12V-2x6 cable is included for direct PCIe 5.0 graphics card connection.

Does the fan stay on constantly or stop at low load?

ECO mode lets the 120 mm FDB fan switch off at low loads for silent operation.
