be quiet! Pure Power 13 M 850W Power Supply vs Lian Li SP850 V2 Gold 850 Watt SFX Form Factor Power Supply

Price Comparison

The be quiet! Pure Power 13 M 850W Power Supply is priced at C$173.21, making it the more affordable option compared to the Lian Li SP850 V2 Gold, which retails for C$194.23. This difference of C$21.02 could be significant for budget-conscious consumers looking to build or upgrade their systems. Given the similar wattage of both power supplies at 850W, the lower price of the Pure Power 13 M may appeal to those seeking efficiency without breaking the bank.

Efficiency and Certification

Both power supplies boast an 80 PLUS Gold certification, ensuring high energy efficiency. The be quiet! Pure Power 13 M achieves an impressive efficiency rating of up to 94.4%, which translates to lower power consumption and operational costs. In contrast, the Lian Li SP850 V2 Gold also meets the ATX 3.1 power standard, supporting PCIe Gen 5.0 and handling transient power spikes effectively. While both models are designed for optimal efficiency, the Pure Power 13 M edges ahead with its superior efficiency rating.

Cooling Technology

Cooling performance is crucial for any power supply, and both the be quiet! Pure Power 13 M and Lian Li SP850 V2 Gold have unique approaches. The Pure Power 13 M features a semi-passive zero-RPM cooling mode, where the fan remains off under low loads, ensuring quiet operation. Conversely, the Lian Li SP850 V2 Gold is equipped with a premium 92mm FDB fan, designed for efficient and quiet thermal performance. Although both options provide quiet operation, the Pure Power 13 M's fan-off feature during low loads may offer a quieter experience during less demanding tasks.

Modularity

When it comes to cable management, the Lian Li SP850 V2 Gold stands out as a fully modular power supply. This means users can connect only the cables they need for their specific builds, reducing clutter and improving airflow. The be quiet! Pure Power 13 M, while not specified as fully modular, provides essential connectors for modern systems, including support for next-generation PCIe 5.1 graphics cards. The modularity of the Lian Li model may offer significant benefits in custom builds or compact cases, where space and airflow are critical considerations.

Build Quality and Reliability

Both power supplies are built to offer reliability and stability, but their approaches differ slightly. The be quiet! Pure Power 13 M uses LLC topology, which is known for providing excellent voltage regulation and efficiency. The Lian Li SP850 V2 Gold, on the other hand, incorporates high-quality Japanese electrolytic capacitors and features an upgraded 5VSB rail, enhancing its capacity for modern USB-powered accessories and standby needs. While both options promise reliability, the Lian Li’s extended hardware protection of 10 years adds an extra layer of assurance for users looking for longevity in their investment.

Compatibility

Compatibility is a key factor for any power supply, especially with the growing demands of modern components. The be quiet! Pure Power 13 M meets all ATX 3.1 specifications and includes native integration of the 12V-2x6 connector designed for next-generation graphics cards, alongside 4 PCIe 6+2-pin connectors for current GPUs. Similarly, the Lian Li SP850 V2 Gold is also ATX 3.1 certified, supporting the PCIe Gen 5.0 platform. Both power supplies are designed to accommodate the latest hardware, but the Pure Power 13 M’s versatility with multiple connectors may give it an edge for users planning to upgrade in the near future.

Noise Levels

Noise levels can significantly impact a user’s experience, particularly in gaming or media creation setups. The be quiet! Pure Power 13 M focuses on silent operation, especially with its semi-passive cooling feature that disables the fan at low loads. Meanwhile, the Lian Li SP850 V2 Gold’s 92mm FDB fan is engineered for quiet thermal performance. Although both power supplies are designed for minimal noise, the Pure Power 13 M’s unique ability to operate silently under low loads may provide a quieter environment overall.

Which should you buy?

Choosing between the be quiet! Pure Power 13 M 850W Power Supply and the Lian Li SP850 V2 Gold ultimately depends on your specific needs and preferences. The Pure Power 13 M is the more budget-friendly option, offering superior efficiency and a unique cooling feature that enhances quiet operation. On the other hand, the Lian Li SP850 V2 Gold provides full modularity and an extended warranty, appealing to users who prioritise cable management and long-term reliability. If price and efficiency are your primary concerns, the be quiet! Pure Power 13 M is your best bet; however, if you value modularity and additional features, the Lian Li SP850 V2 Gold could be worth the extra investment.
