1000 W ATX12V 3.1 power supply

The Fractal Design Ion 3 Gold delivers 1000 W of continuous power through a single +12 V rail. It is built for high-end desktop systems that demand stable output under heavy load. Fully modular cabling keeps the build tidy and improves airflow inside the case.

80 PLUS Gold efficiency and GPU headroom

The unit meets 80 PLUS Gold certification and reaches =45 % ErP Lot 6 compliance at low load. A native 16-pin PCIe Gen 5 12V-2×6 cable supports modern graphics cards, while additional 6+2 pin connectors cover other GPUs. Power excursion handling helps absorb transient spikes without tripping protection.

Upgrade from group-regulated or lower-wattage units

Replacing an older group-regulated design or a supply below 1000 W removes cross-load instability and adds headroom for power-hungry GPUs. The ATX12V 3.1 platform ensures compatibility with current and upcoming component specifications. The jump is worthwhile when the existing unit cannot sustain peak GPU demands.

Questions about this item

Will the single 12 V rail and 1000 W output handle a modern high-end GPU without extra adapters?

Yes, the unit includes a native 16-pin PCIe Gen 5 12V-2×6 cable at 700 mm plus PCI-E 6+2 pin cables at 650 mm for direct GPU power.

Does the fully modular design and cable lengths suit a standard mid-tower case?

Cables are 400 mm to 700 mm long; the PSU measures 150 x 150 x 86 mm, fitting typical ATX bays with room for routing.

How quiet is the fan under light loads and can it stop completely?

A Momentum 14 fan with fluid dynamic bearing runs variable speed and offers a Zero RPM mode for near-silent operation at low load.
