1000 W Platinum ATX 3.1 power supply

The Phanteks AMP GH 1000 W unit delivers 80 PLUS Platinum efficiency on an Intel ATX 3.1 platform with PCIe 5.1 support. A fully modular design uses individual textured cables and includes cable combs for clean routing. A 120 mm fluid dynamic bearing fan enables a zero-RPM mode below 40 % load for silent operation.

Suited to high-end GPU builds needing 12V-2x6 power

This PSU targets builders installing modern graphics cards that draw up to 600 W through a single 12V-2x6 connector. The compact 140 mm depth fits standard ATX cases. Buyers who need more than 1000 W of continuous power or require multiple 12V-2x6 cables for dual-GPU configurations should look at higher-capacity or multi-connector units.

1000 W capacity with 600 W GPU headroom

The 1000 W rating comfortably handles a flagship CPU plus a single 600 W-class graphics card with overhead for drives and peripherals. The 12V-2x6 cable covers the highest single-GPU demand defined by the current specification. Systems planning dual flagship GPUs or extreme overclocking beyond the rated output will exceed the available headroom.

Questions about this item

Does my case need to fit a 140 mm deep ATX power supply for this unit to install?

Yes, the PSU is built to the compact ATX form factor with a 140 mm depth, so the case must accommodate that length for a proper fit.

Will the 12V-2x6 cable work with a graphics card that still uses the older 12VHPWR connector?

The 12V-2x6 connector is the updated PCIe 5.1 interface and is backward compatible with existing 12VHPWR plugs, so the single cable can deliver up to 600 W to either design.

How can I confirm the fanless mode is active once the system is running?

Under 40 % load the 120 mm fluid-dynamic-bearing fan stops completely, so silent operation at low power draw confirms the zero-RPM mode is working.
