Product overview

Released in May 2023, the Pure Power 12 M 1200W is the top-capacity model in be quiet!’s Pure Power 12 M family—an ATX 3.0, 80 Plus Gold, fully modular line positioned for modern GPU readiness. It expands the series above the long‑running 1000W SKU and keeps the same dual‑rail design and native PCIe 5.0 cabling.

This is an enthusiast‑tier PSU: Gold efficiency, fully modular, and very high wattage. It exists to deliver ATX 3.0 compliance and native 12VHPWR in a cost‑efficient, ATX‑sized unit. Good for high-end GPU builds, ATX 3.0 GPUs, and users wanting headroom/overclocking; the 600W 12VHPWR plus four 6+2‑pin PCIe leads, dual 12V rails, and a 10‑year warranty make it suitable for powerful single‑GPU systems with room to grow. Unique: native 12VHPWR on an ATX 3.0 Gold platform with fully modular cabling.
