Purpose & audience

The Phanteks AMP GH is a 1000W ATX 3.0 power supply built for high-end desktop builds. Its 600W 12VHPWR connector supports 4090 series graphics cards out of the box. Fully modular cabling keeps the interior tidy for system integrators and enthusiasts who value clean cable routing.

Capacity & headroom

The unit delivers 83A on the +12V rail with minor rails rated at 20A for +5V and +3.3V. A 600W 12VHPWR output provides ample headroom for flagship GPUs under sustained load. Builders planning multi-GPU arrays or extreme overclocking beyond the 1000W total will need a higher-capacity platform.

Thermals, noise & power

Hybrid fan mode stops the fan at low loads for silent operation, then spins up only when thermal demand rises. The compact 140 mm x 150 mm x 86 mm chassis fits standard ATX bays while maintaining Platinum efficiency across the 100-240Vac input range. Continuous 1000W output is rated within the specified operating temperature envelope.

Questions about this item

Will the 12VHPWR connector on this unit deliver 600W to a 4090 while my older PSU only had 8-pin PCIe cables?

The 12VHPWR connector and cable are included and rated for 600W output. A compatible graphics card is required to use it.

How can I confirm the hybrid fan mode is active after installation?

Hybrid mode keeps the fan off at low loads and starts it when temperatures rise. You will hear the fan spin up only under heavier demand.

Which cables come in the box and what must I source separately?

The fully modular unit includes the 12VHPWR cable and a U.S. standard power cord. Other modular cables for motherboard, CPU and drives are also supplied.
