be quiet! Pure Power 13 M 1200W ATX 3.1 80+ Gold PSU
The be quiet! Pure Power 13 M 1200W ATX 3.1 80+ Gold PSU is designed for PC builders who need a high-wattage, quiet, and efficient foundation for gaming rigs or media creation workstations. It delivers 1200W of continuous power with full ATX 3.1 and PCIe 5.1 compliance, making it ready for today's most demanding graphics cards and the next generation of components. Fully modular cabling and a semi-passive fan keep the build clean and the noise floor low.
Why this product
Up to 93.5% efficiency, 80 PLUS Gold certified
Gold-level efficiency means less energy is lost as heat, keeping the system cooler and reducing electricity costs over time.
ATX 3.1 and PCIe 5.1 ready out of the box
It ships with a native 12V-2x6 connector rated up to 600W for next-generation PCIe 5.1 GPUs, plus four PCIe 6+2-pin connectors for current-generation cards — no adapters needed.
Handles power excursions up to double rated wattage
The single 12V rail at 100A absorbs short-duration power spikes up to twice the unit's rated output, protecting stability when a GPU briefly demands excessive power.
Semi-passive fan goes completely silent under light load
The fan switches off entirely at low load levels and measures just 9.8 dB(A) between 10–20% load, rising to a maximum of 32.3 dB(A) only at full load.
Fully modular cabling for cleaner builds
Every cable is detachable, so unused cables stay out of the case entirely, simplifying routing and improving airflow.
10-year manufacturer warranty
A decade of coverage from be quiet! reflects long-term confidence in the unit's reliability and gives builders lasting assurance.

Best for
- High-end gaming PC builders pairing a PCIe 5.1 GPU with a power-hungry CPU who need 1200W of headroom and a native 12V-2x6 connection without adapters.
- Noise-sensitive builders who want a PSU that runs completely silently under everyday desktop and light gaming loads, thanks to the zero-RPM semi-passive mode.
- Media creation and workstation users running GPU-intensive workloads who benefit from Gold-level efficiency and stable single-rail delivery.
- Long-term builders who value a 10-year warranty and ATX 3.1 compliance that keeps the unit relevant for the next generation of hardware.
- Cable-management enthusiasts who want a fully modular supply so no unused cables clutter the interior of the case.
Trade-offs
- Small-form-factor builds — at 160 × 150 × 86 mm and ATX form factor, it will not fit SFX or SFX-L cases.
- Budget-constrained system builds where a lower wattage supply would be sufficient; 1200W capacity carries a cost premium over lower-tier Pure Power 13 M variants.
- Platinum or Titanium efficiency seekers — 80 PLUS Gold tops out at up to 93.5% efficiency; builders targeting the highest possible efficiency tier should look at higher-rated units.
- Non-modular preference builds — all cables must be routed and connected manually; builders who prefer a fixed-cable layout will not benefit from the modular design.
Pure Power 13 M 1200W is certified 80 PLUS Gold with an outstanding efficiency rating of up to 93.5%. The most compelling benefit: lower power consumption, consequently lower costs, and above all a cooler as well as quieter operation. Pure Power 13 M 1200W is always the correct choice for quiet systems and gaming PCs!
Pure Power 13 M 1200W is an ATX 3.1 PSU and comes with both native integration of the 12V-2x6 connector for next-generation PCIe 5.1 graphics cards, and 4 PCIe 6+2-pin connectors for support of current-gen GPUs. This makes the PSU extremely versatile and the perfect choice for powerful systems of today and the ones to come.
Pure Power 13 M offers 1200W of continuous power with one massive 12V rail. Even if the graphics card demands excessive power for a short time: Pure Power 13 M 1200W handles power excursions up to double its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards.
While under low load, the fan turns off completely until its services are needed again for more demanding operations. This feature, combined with the reliable be quiet! fan and its airflow-optimized fan blades, make Pure Power 13 M 1200W exceptionally silent in all load scenarios.
With its LLC topology Pure Power 13 M 1200W provides best-in-class voltage regulation and efficiency. That makes it perfect for building very quiet systems or upgrading gaming and media creation PCs.
Thanks to their modularity, all unnecessary cables in the system are left out. Pure Power 13 M 1200W simplifies cable management and routing for a tidy-looking system.
