Fractal Design Ion 3 Gold 1000W White FD-P-IA3G-101-US-WT power supply

Next-gen power delivery

This 1000 W unit follows the ATX12V 3.1 specification and carries 80 PLUS Gold certification. It targets builders who need stable output for modern graphics cards that draw sudden power excursions. The single +12 V rail simplifies load balancing across demanding components. Full modularity lets you connect only the cables your build requires.

Build quality and daily connections

Japanese 105°C capacitors and a Momentum 14 fan with fluid dynamic bearing and LCP blades form the core of the cooling and longevity strategy. Variable fan speeds adapt to load, while a Zero RPM mode stops the fan entirely under light work. UltraFlex cables reduce routing friction inside the case. The package includes a 16-pin PCIe Gen 5 12V-2×6 cable at 700 mm and multiple PCI-E 6+2 pin cables at 650 mm, plus SATA runs at 400 mm and 650 mm with 150 mm increments.

Upgrade path and when it matters

The unit replaces older ATX12V designs that lack native 12V-2×6 support and excursion handling. If your current supply cannot deliver the transient peaks demanded by newer GPUs, this model closes that gap. The 90 000-hour MTBF and 10-year coverage reflect component confidence. Buyers moving from group-regulated or non-modular units gain cleaner cable management and tighter voltage regulation.
