Model PH-P750GH_BK01

  • ATX 3.1 platform ready for PCIe 5.1 GPUs with 12V-2x6 connector up to 600W
  • 80 PLUS Gold efficiency keeps running costs low and heat output minimal
  • Zero-RPM fan mode below 40% load gives near-silent operation at typical desktop loads
  • Fully modular individual textured cables with combs simplify routing and improve case airflow
  • 120 mm fluid dynamic bearing fan rated beyond 100,000 hours MTBF for long-term reliability

750W ATX 3.1 Power Supply

The Phanteks AMP GH 750W unit delivers 750 W through a fully modular design with individual textured cables and included cable combs. It uses 100% Japanese capacitors and a 120 mm fluid dynamic bearing fan. The 80 PLUS Gold certification confirms high efficiency for modern system builds.

ATX 3.1 and PCIe 5.1 Platform Limits

The platform follows ATX 3.1 specifications and includes a native 12V-2x6 connector rated for 600 W on a single cable. This interface supports current GPU power demands without adapters. The compact 140 mm depth fits standard ATX layouts while maintaining the required power density.

Upgrading from Older ATX Units

Builders moving from power supplies without a native 12V-2x6 connector or ATX 3.1 compliance gain direct support for latest-generation graphics cards. The jump is worth it when a new GPU requires 600 W through one cable or when the zero-RPM fan mode under 40 % load reduces system noise.

Questions about this item

Should I pick the 750 W, 850 W, 1000 W or 1200 W model for my build?

Choose the 750 W unit if your GPU and CPU together draw under 600 W; step up to 850 W, 1000 W or 1200 W for higher multi-GPU or extreme overclocking headroom.

What does the 750 W rating actually deliver inside my PC?

It supplies up to 750 W of continuous DC power across all rails with 80 PLUS Gold efficiency, and the 12 V rail can push 600 W through the single 12V-2x6 connector.

How does the ATX 3.1 and PCIe 5.1 platform limit what I can plug in?

The PSU meets ATX 3.1 specs and includes a native 12V-2x6 cable rated for 600 W, so it supports current Gen 5.1 graphics cards without adapters.
