CORSAIR RM850e vs be quiet! Pure Power 13 M 850W Power Supply

Price Comparison

The CORSAIR RM850e is priced at C$184.99, while the be quiet! Pure Power 13 M 850W Power Supply is slightly cheaper at C$173.21. This makes the be quiet! option more budget-friendly, saving consumers approximately C$11.78. Price can be a significant factor for many builders, especially when both products offer similar wattage and features. If budget constraints are a priority, the be quiet! model presents a compelling argument due to its lower cost.

Efficiency Ratings

The be quiet! Pure Power 13 M boasts an impressive 80 PLUS Gold certification with an efficiency rating of up to 94.4%. In contrast, while the CORSAIR RM850e is Intel ATX 3.1 Certified, specific efficiency ratings are not provided in the data. The high efficiency of the Pure Power 13 M means it consumes less power during operation, resulting in lower electricity bills and a cooler system. This makes the be quiet! model a more energy-efficient choice, particularly for users focused on reducing power consumption.

Modular Design

Both power supplies feature fully modular designs, which allow users to connect only the cables they need. This is a significant advantage for cable management and airflow within a PC case. The CORSAIR RM850e's fully modular nature ensures a clean and tidy build without unnecessary clutter. Meanwhile, the be quiet! Pure Power 13 M also emphasizes cable management, making it versatile for various builds. Users prioritising aesthetics and airflow may find both options highly appealing, as modular designs are essential for optimal system performance.

Cooling Features

The cooling capabilities of these power supplies differ significantly. The CORSAIR RM850e utilizes a 120mm rifle-bearing fan with a specially calculated fan curve to minimize noise, even under full load. On the other hand, the be quiet! Pure Power 13 M incorporates a semi-passive zero-RPM cooling feature, meaning the fan remains off during low load to ensure silence. This unique approach allows the Pure Power 13 M to operate quietly, making it ideal for users who require a silent system. Thus, for those prioritizing noise levels, the be quiet! model holds an advantage.

Compatibility and Future-Proofing

Both power supplies comply with the latest ATX 3.1 specifications, making them future-proof choices for modern builds. The be quiet! Pure Power 13 M goes a step further by featuring native integration of the 12V-2x6 connector, which supports next-generation PCIe 5.1 graphics cards and includes four PCIe 6+2-pin connectors for current-generation GPUs. This makes it an incredibly versatile option for future upgrades. While the CORSAIR RM850e also supports the latest standards, its lack of specific connector details may make it less appealing for users focused on future-proofing their systems.

Build Quality and Components

The CORSAIR RM850e is constructed with 105°C-rated capacitors, ensuring reliable power delivery and performance. This high-quality component choice enhances the overall stability of the power supply. Similarly, the be quiet! Pure Power 13 M features LLC topology for best-in-class voltage regulation and efficiency. Both power supplies are built with durability in mind, but the emphasis on high-temperature rated capacitors in the CORSAIR model may give it a slight edge in long-term reliability. Users seeking a robust build quality may want to consider these factors when making a decision.

Noise Level Performance

When it comes to noise levels, the be quiet! Pure Power 13 M is designed for quiet operation, especially under low loads thanks to its semi-passive cooling feature. This allows the fan to turn off completely when not needed, contributing to a quieter environment. The CORSAIR RM850e, while designed to keep noise down with its specially calculated fan curve, may not achieve the same level of silence as the be quiet! model during low-load scenarios. Thus, for users who value a whisper-quiet system, the be quiet! option stands out.

Which should you buy?

In conclusion, both the CORSAIR RM850e and be quiet! Pure Power 13 M are excellent choices for those in need of a reliable 850W power supply. The be quiet! model offers a lower price, higher efficiency rating, and superior silent operation due to its semi-passive cooling feature, making it an attractive option for budget-conscious users and silent PC builders. On the other hand, the CORSAIR RM850e is built with high-quality components and may provide better reliability over time. Ultimately, the decision will depend on whether you prioritize price and quiet operation or component quality and performance consistency.
