1200W Platinum ATX 3.1 power supply

The Phanteks AMP GH delivers 1200 W of continuous power on the Intel ATX 3.1 platform with PCIe 5.1 support. It uses 100 % Japanese capacitors and carries 80 PLUS Platinum certification. A 120 mm fluid dynamic bearing fan enables a zero-RPM mode below 40 % load for silent operation. The unit is fully modular with a compact 140 mm depth.

Individual textured cables and 12V-2x6 connector

Fully modular design ships with individually textured cables and included cable combs for clean routing. The native 12V-2x6 GPU cable supports up to 600 W through a single connection, meeting the latest PCIe 5.1 specification. This removes the need for adapters or daisy-chained connectors on modern graphics cards.

High-power builds needing ATX 3.1 and quiet running

Suits builders assembling high-end systems that require ATX 3.1 compliance, 1200 W headroom and a 140 mm deep form factor. The zero-fan mode appeals to users prioritising low noise at typical loads. Not for buyers who need a smaller SFX footprint, a lower wattage unit, or a non-modular design to reduce cost.

Questions about this item

When will the 120 mm fan need replacement?

The fan is rated for more than 100000 hours of operation, so replacement is unlikely during typical system life.

What protection trips first during a sustained 1200 W load?

Over Temperature Protection will activate if internal temperatures exceed safe limits before any other protection engages.

How loud and hot does the unit get when running all day at high load?

Above 40% load the 120 mm fluid dynamic bearing fan spins up; below that threshold it stays at 0 RPM for silent operation.
