be quiet! Pure Power 13 M 850W ATX 3.1 Power Supply

The Pure Power 13 M 850W is an ATX 3.1 compliant and PCIe 5.1 compatible power supply designed for modern gaming and workstation builds. With 80 PLUS Gold efficiency reaching up to 94.4%, this PSU delivers reliable power while minimizing energy waste and heat generation.

Next-Generation Graphics Card Compatibility

Equipped with both a PCIe 5.1 12V-2x6 600W cable and four PCIe 6+2 pin connectors, the Pure Power 13 M 850W provides exceptional compatibility with current and next-generation graphics cards. The single 12V rail delivers 70.9A of stable power, capable of handling massive power excursions from high-end GPUs without compromising system stability.

Silent Semi-Passive Cooling

The 120mm be quiet! fan with rifle bearing technology operates in semi-passive mode, remaining completely silent during light loads. At 20% load, noise levels measure just 12.9 dB(A), ensuring whisper-quiet operation during everyday tasks. The 4-pole fan motor with a maximum speed of 2000 rpm only activates when necessary, balancing thermal performance with acoustic efficiency.

Advanced Power Delivery

LLC topology combined with DC/DC conversion ensures advanced voltage regulation and stability across all rails. The PSU maintains a power factor greater than 0.98 at full load and supports modern standby with less than 0.1W power consumption. With a hold-up time of 25.09ms at 100% load, the Pure Power 13 M 850W protects your system during brief power interruptions.

Comprehensive Protection Suite

Full safety features include OTP (over temperature protection), OCP (over current protection), OPP (over power protection), SCP (short circuit protection), OVP (over voltage protection), UVP (under voltage protection), and SIP (surge & inrush protection). These safeguards protect both the PSU and your connected components from electrical anomalies.

Flexible Cable Management

The semi-modular design includes flat, sleeved cables for improved airflow and aesthetics. With six SATA connectors, dual P4+4 and P8 CPU connectors, and a 55cm motherboard cable, this PSU accommodates various build configurations. Cable lengths extend up to 95cm, providing flexibility for larger cases.

Long-Term Reliability

Backed by a 10-year manufacturer's warranty and an average lifetime exceeding 100,000 hours at 25°C, the Pure Power 13 M 850W is built for longevity. The 160 x 150 x 86mm casing houses premium components that operate reliably at temperatures up to 40°C.

Pure Power 13 M 850W 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. Having both a PCIe 5.1 cable and PCIe 6+2 cables in the scope of delivery, this PSU offers outstanding compatibility with current-gen and next-gen graphics cards. Pure Power 13 M 1000W offers the best combination of features with outstanding compatibility.
