Compact 1000 W ATX 3.0 supply

The Phanteks AMP GH delivers 1000 W in a 140 mm x 150 mm x 86 mm fully modular chassis. A single 140 mm fan handles airflow while the white finish suits bright-themed builds. The unit targets owners of high-end graphics cards such as the 4090 series who need a native 12VHPWR connection. Builders requiring more than 1000 W or a different form factor should look elsewhere.

Hybrid fan curve and Platinum efficiency

The supply meets 80 PLUS Platinum certification across 100-240 Vac at 50-60 Hz. Hybrid mode keeps the 140 mm fan off at low load for silent operation. On the +12 V rail the unit provides 83 A, while +5 V and +3.3 V rails each deliver 20 A. The 12VHPWR output is rated for 600 W to feed modern GPUs directly.

Native 12VHPWR cable and modular loom

A dedicated 12VHPWR cable ships in the box so no adapter is needed for compatible Gen5 graphics cards. Full modularity lets you connect only the cables your build requires, reducing clutter inside compact cases. The package also includes a U.S. standard power cord for the Chinese-model unit. Users without a 12VHPWR-equipped GPU gain no advantage from the specialised connector.

Questions about this item

How do I install the 12VHPWR cable for a 4090 card and what step is often missed?

Connect the 12VHPWR cable directly to the PSU and GPU, ensuring the connector seats fully until the latch clicks; the cable is included and rated for 600 W output.

What maintenance will this unit need over time?

Clean the 140 mm fan intake periodically to prevent dust buildup; the fully modular design lets you remove cables for easier access.

What limit appears first under sustained heavy load?

The 12VHPWR connector is rated for 600 W, so a GPU drawing near that ceiling will hit its cable limit before the 1000 W total capacity.
