be quiet! Pure Power 13 M 550W ATX 3.1 PSU 80+ Gold
The be quiet! Pure Power 13 M 550W ATX 3.1 PSU is built for builders and gamers who want a power supply that runs quietly and efficiently without sacrificing compatibility with current or next-generation graphics cards. It delivers 550W of continuous power with support for PCIe 5.1 and handles temporary power spikes up to 1100W, making it suitable for high-end gaming and workstation builds.
Why this product
PCIe 5.1 ready with dual GPU connectors
It includes a native 12V-2x6 connector for next-generation graphics cards alongside two PCIe 6+2-pin connectors, so it works with current GPUs and is prepared for newer designs.
80 PLUS Gold efficiency up to 93.8%
High efficiency means lower power draw from the wall, reduced heat output, and quieter fan operation over time.
Semi-passive cooling: fan off under light loads
The 120mm fan stops completely during idle or low-demand periods, eliminating noise when you need silence most.
Handles power spikes up to 1100W transient
Even though the PSU is rated 550W, it can sustain temporary power excursions up to double its rated output, protecting against the brief peak demands of high-end graphics cards and CPUs.
Fully modular cables
Remove only the connectors you need to reduce cable clutter, improve airflow, and simplify cable routing in your case.
10-year manufacturer warranty
be quiet! backs this PSU with a full decade of coverage, reflecting confidence in the design.

Best for
- Gaming PCs running high-end GPUs
- Builders prioritizing quiet operation
- Systems designed for minimal cable clutter
- Future-proofing for PCIe 5.1 graphics cards
- Long-term ownership with extended warranty coverage
Trade-offs
- Very high-wattage systems. At 550W continuous output, it is not suitable for builds requiring sustained power above that threshold.
- Ultra-silent passive systems. While exceptionally quiet, the fan does operate under load; passive-only cooling is not available.
- Budget-constrained builds. The 80 PLUS Gold efficiency and modular design come at a higher price than non-modular Bronze-rated alternatives.
Pure Power 13 M 550W is an ATX 3.1 compliant and PCIe 5.1 compatible power supply with semi-passive cooling. It offers peerless dependability with best-in-class features. Pure Power 13 M 550W offers the best combination of features with outstanding compatibility.
Pure Power 13 M 550W is certified 80 PLUS Gold with an outstanding efficiency rating of up to 93.8%. The most compelling benefit: lower power consumption, consequently lower costs, and above all a cooler as well as quieter operation. Pure Power 13 M 550W is always the correct choice for quiet systems and gaming PCs!
Pure Power 13 M 550W 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 2 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 550W of continuous power with one massive 12V rail. Even if the graphics card demands excessive power for a short time: Pure Power 13 M 550W 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 550W exceptionally silent in all load scenarios.
Thanks to their modularity, all unnecessary cables in the system are left out. Pure Power 13 M 550W simplifies cable management and routing for a tidy-looking system. A smoother airflow results from the uncluttered layout of the system, which means lower noise and temperatures inside the case.
