be quiet! Pure Power 13 M 850W Power Supply vs CORSAIR CX750M

Price Comparison

When considering the price, the CORSAIR CX750M is significantly more affordable at C$124.99 compared to the be quiet! Pure Power 13 M 850W, which is priced at C$173.21. This difference of C$48.22 makes the CORSAIR a more budget-friendly option, especially for users who are looking for a reliable power supply without breaking the bank. While both power supplies offer a range of features, the price gap is notable, making the CORSAIR a more attractive choice for those on a tighter budget.

Efficiency Ratings

The be quiet! Pure Power 13 M 850W boasts an impressive 80 PLUS Gold certification with an efficiency rating of up to 94.4%. This high efficiency not only translates to lower power consumption but also results in reduced operational costs over time. In contrast, while the CORSAIR CX750M meets the latest ATX 3.1 and PCIe 5.1 standards, specific efficiency ratings are not highlighted in the available data. The efficiency of the Pure Power 13 M 850W positions it as an ideal choice for energy-conscious users, especially in high-performance gaming or professional setups.

Power Output

With a continuous power output of 850W, the be quiet! Pure Power 13 M is designed to handle demanding graphics cards and processors. Its single, robust 12V rail can manage power excursions up to double its rated power, ensuring stability during peak loads. On the other hand, the CORSAIR CX750M provides a maximum output of 750W, which is still substantial for most mid-range gaming setups. However, for users planning to build high-performance systems with cutting-edge components, the be quiet! model offers more headroom and reliability under stress.

Cooling Features

The cooling mechanisms of both power supplies are designed to enhance performance and longevity. The be quiet! Pure Power 13 M incorporates a semi-passive zero-RPM cooling feature, allowing the fan to remain off under low loads, resulting in an exceptionally silent operation. This is ideal for quiet systems, such as home theatres or office PCs. In comparison, the CORSAIR CX750M is equipped with a 120mm low-noise fan that operates quietly, particularly under low and medium loads. While both units excel at noise reduction, the unique zero-RPM feature of the Pure Power 13 M may be more appealing to users prioritizing silence.

Connectivity Options

Connectivity is critical for ensuring compatibility with modern components. The be quiet! Pure Power 13 M includes both native integration of the 12V-2x6 connector for next-gen PCIe 5.1 graphics cards and four PCIe 6+2-pin connectors for current-generation GPUs. This versatility makes it future-proof for upcoming technology. Conversely, the CORSAIR CX750M also features a native 12V-2x6 cable, which eliminates the need for adapters when connecting to the latest Nvidia RTX 50-series GPUs. While both power supplies cater to modern graphics cards, the broader range of connectors in the Pure Power 13 M may provide an edge for users with diverse hardware needs.

Build Quality and Reliability

Build quality is essential for long-term reliability. The be quiet! Pure Power 13 M is constructed with high-quality components designed to provide rock-solid stability, thanks to its LLC topology that ensures excellent voltage regulation. This makes it particularly well-suited for high-performance systems. The CORSAIR CX750M, while also built to last, does not explicitly highlight its internal design features in the data provided. Users seeking a power supply that promises superior reliability under demanding conditions may find the Pure Power 13 M's specifications more reassuring.

Target Audience

The target audience for each power supply differs based on power needs and budget. The be quiet! Pure Power 13 M, with its higher wattage, 80 PLUS Gold efficiency, and superior cooling capabilities, is likely aimed at gamers and professionals who require a robust and silent power solution for powerful systems. Conversely, the CORSAIR CX750M caters to those seeking a reliable, cost-effective power supply for mid-range builds. Its lower price point and sufficient power output make it an excellent choice for mainstream users who do not require the highest performance levels.

Which should you buy?

Ultimately, the decision between the be quiet! Pure Power 13 M 850W and the CORSAIR CX750M comes down to your specific needs and budget. If you’re looking for maximum efficiency, higher power output, and superior cooling features for a demanding setup, the be quiet! Pure Power 13 M is the better choice. However, if you’re on a budget and need a reliable power supply for a mid-range system, the CORSAIR CX750M offers great value without sacrificing essential features. Consider your priorities carefully to make the best choice for your build.
