Phanteks AMP GH Spec and Price in the United States
AMP GH is Phanteks' mainstream ATX 3.1 line and its selling point is density: 140mm deep, which is short for a unit that reaches 1200W, with a 120mm hydro-dynamic-bearing fan that stays off below 30% load. The ladder changes tier partway up — 750W and 850W are 80 PLUS Gold with a 450W 12V-2x6 cable, while the 1000W and 1200W are Platinum and carry the full 600W on that connector. Fully modular with individually textured cables, gold-plated output terminals, and an eight-year limited warranty across the range.

What owners and reviewers say
Summarised from 1 source(s), reviewed September 14, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Reviewers measured excellent 12V regulation and low ripple throughout, with Japanese capacitors and fanless operation at low loads.
- It is fully modular in a compact 140mm chassis, ships with a thorough bundle, carries an eight-year warranty and is aggressively priced.
Commonly criticised
- Its 12V-2x6 connector is capped at 450W, it uses a sleeve-bearing fan, and its efficiency certification listing is outdated.
