1000W ATX 3.1 Power Supply

This 1000W unit targets builders who need a compact, fully modular supply for high-end graphics cards and multi-drive systems. It meets the ATX 3.1 and PCIe 5.1 specifications and includes a native 12VHPWR cable. The 150mm length helps it fit in space-constrained cases.

Full Modular Ribbon Cables && Cybenetics Platinum

Every cable is detachable and uses a ribbon layout to simplify routing and reduce clutter inside the chassis. The supply carries 80 PLUS Gold and Cybenetics Platinum certifications, reaching 87% efficiency at 20% load, 90% at 50% load and 87% at 100% load on 115V input, with 89% to 93% overall efficiency across 115V and 230V ranges. The 140mm fluid-dynamic-bearing fan and 105°C Japanese capacitors support quiet, reliable operation.

Single +12V Rail && 12 SATA Connectors

A single +12V rail delivers the full 1000W to the GPU and CPU without multi-rail balancing concerns. Twelve SATA power connectors provide headroom for multiple SSDs, hard drives and peripheral devices. Protection circuits include over-voltage and overload safeguards. The unit operates on 90–264V input at 47–63Hz, making it suitable for global use without a voltage switch. Builders who require more than 1000W or need a 16-pin socket on the PSU side should look elsewhere.

Questions about this item

What maintenance does the 140 mm fluid dynamic bearing fan need over time?

The 140 mm fluid dynamic bearing fan is sealed and requires no lubrication; dust can be cleared with compressed air when the case is open.

What limits sustained output before the 1000 W rating is reached?

The single +12 V rail delivers the full 1000 W, and over-voltage plus overload protection will trip if that limit is exceeded.

How loud and hot does the unit get when running all day at typical load?

Cybenetics Standard ++ noise rating and 89 % to 93 % efficiency at 115 V or 230 V input keep acoustic output low and waste heat minimal during continuous operation.
