Model Ion 3 Gold 1000W White

  • ATX12V 3.1 compatibility keeps next-gen components stable
  • 16-pin PCIe Gen 5 12V-2×6 cable powers modern GPUs securely
  • Momentum 14 fan with fluid dynamic bearing runs quieter and lasts longer
  • 80 PLUS Gold certification cuts energy waste and heat output
  • Fully modular UltraFlex cables simplify routing for a cleaner build

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.

Questions about this item

What does the ATX12V 3.1 standard mean for power delivery on this unit?

The ATX12V 3.1 design supports GPU power excursions, allowing the 1000 W supply to handle transient spikes from modern graphics cards without tripping protection circuits.

What are the physical dimensions and mounting requirements for this power supply?

The unit measures 150 x 150 x 86 mm and uses standard ATX mounting points, fitting most cases that accept a 150 mm deep PSU with four rear screws.

How do I correctly install the 16-pin PCIe Gen 5 12V-2x6 cable and what is the common mistake?

Plug the 16-pin connector fully into the GPU until the latch clicks; the shortened sense pins must seat completely, otherwise the card may not power on or will run in a reduced-power state.
