ATX 3.1 1000 W fully modular PSU

This 1000 W unit meets the ATX 3.1 standard and carries 80 PLUS Gold certification. It is built for modern high-performance PCs that need stable, efficient power delivery. The fully modular design lets you connect only the cables your build requires. ||

Sustained load efficiency and noise

At 115 V and full load the supply reaches 89.53 % efficiency, keeping heat and power draw low during long sessions. Cybenetics rates the C1000 at A+ for noise, meaning 15–20 dBA under load. The 135 mm fluid dynamic bearing fan stops completely in Zero RPM mode when cooling demand is light. ||

Premium caps, 12V-2x6 connector, modular cables

All capacitors are rated for 105 °C, supporting reliable operation across varied loads. A dual-colour 12V-2x6 connector rated for 600 W shows when the link is secure and is ready for PCIe 5.1 graphics cards. Eight SATA connectors and two 6+2-pin PCIe cables cover legacy GPUs and storage. The 150 mm depth fits most ATX cases.

Questions about this item

How loud is the 135 mm fan when the PSU runs at full load all day?

Cybenetics rates the C1000 at A+ for noise, meaning 15 to 20 dBA under load, and the fluid dynamic bearing fan stops completely in Zero RPM mode during light workloads.

Which cables must I already have to use the 12V-2x6 connector on a modern GPU?

The unit ships with a dual-colour 12V-2x6 cable rated for 600 W, so no extra cable is required for PCIe 5.1 graphics cards.

Will the 24-pin ATX and 8-pin EPS connectors work with a motherboard built to the older ATX 2.x spec?

Yes, the PSU follows ATX 3.1 and EPS12V standards, which remain backward compatible with earlier ATX 2.x motherboards.
