White ATX 3.1 platform for next-gen GPUs

The Phanteks AMP GH 850W Gold unit delivers 850 W through a fully modular design with individually textured cables and cable combs. A 120 mm fluid-dynamic-bearing fan enables a zero-RPM mode below 40 % load for silent operation. The platform uses 100 % Japanese capacitors and meets 80 Plus Gold efficiency standards. It includes a native 12V-2x6 connector rated for 600 W to power modern graphics cards.

Replaces older ATX supplies lacking PCIe 5.1 support

Builders moving from a unit without the 12V-2x6 connector gain a single-cable GPU connection that carries up to 600 W. The jump is worth it when a new graphics card requires that connector or when the previous supply cannot sustain 850 W continuously. The compact 140 mm depth also fits cases where longer units would not.

Suits high-performance builds with modern GPUs

This supply fits enthusiasts assembling systems around current-generation graphics cards that draw up to 600 W through one cable. It is not for buyers who need more than 850 W total output, nor for compact builds that require an SFX form factor. Users without a PCIe 5.1 GPU will not use the 12V-2x6 connector.

Questions about this item

What depth case is needed for the 140 mm long PSU?

The unit is 140 mm deep so any ATX case that accepts a 140 mm power supply will fit it.

Which cable do I plug into a PCIe 5.1 graphics card and how far do I push it?

Use the included 12V-2x6 cable; push it in until the latch clicks to deliver up to 600 W.

When should I clean the 120 mm fan and how long is the unit rated to run?

Clean the fan when dust builds up; the MTBF is over 100,000 hours.
