Overview of the Lian Li SP850 V2 Gold

The Lian Li SP850 V2 Gold is a fully modular power supply that retails for C$194.23. This model stands out with its compliance to the ATX 3.1 power standard, making it suitable for modern high-performance systems, particularly those using PCIe Gen 5.0 graphics cards. With a 10-year hardware protection guarantee, the Lian Li SP850 V2 Gold aims to offer not just performance but also longevity.

The power supply features a premium 92mm Fluid Dynamic Bearing fan designed for quiet operation and efficient thermal performance. Additionally, its upgraded 5VSB rail increases current capacity, catering to the needs of contemporary power-hungry peripherals. The modular design allows users to connect only the necessary cables, minimizing clutter and improving airflow within the PC case. Together, these features position the Lian Li SP850 V2 Gold as a top-tier choice for enthusiasts and gamers.

Performance Comparison

When it comes to performance, the Lian Li SP850 V2 Gold clearly outshines the MSI MAG A550BN. The MSI MAG A550BN, while reliable, is only rated at 550 watts, which may be sufficient for basic setups but could struggle with high-end components. In contrast, the Lian Li SP850 V2 Gold boasts an output of 850 watts, providing ample headroom for power-hungry systems that include high-performance CPUs and GPUs.

The modular design of the Lian Li unit allows for better cable management and airflow, which is essential for maintaining optimal operating temperatures in demanding environments. Meanwhile, the MSI MAG A550BN, although equipped with a low noise fan, lacks the advanced cooling features and power output of its counterpart. Thus, for users looking for robust performance, the Lian Li model is the clear winner.

Warranty and Reliability

The MSI MAG A550BN comes with a 5-year limited warranty, which provides a reasonable assurance of reliability for budget builds. This warranty is decent, especially for a power supply in this price range, but it may not be as reassuring for those investing in more expensive hardware.

On the other hand, the Lian Li SP850 V2 Gold offers a notable 10-year hardware protection guarantee. This extended warranty reflects the manufacturer's confidence in the product's durability and reliability over time. Furthermore, the upgraded components and ATX 3.1 certification imply that the Lian Li power supply is built to handle modern demands and potential power spikes. Therefore, for users prioritising warranty and reliability, the Lian Li SP850 V2 Gold is undeniably the superior option.

Noise Levels

Both power supplies are designed to operate quietly, but they achieve this in different ways. The MSI MAG A550BN features a low noise fan that allows for quieter operation, which is beneficial for users who prefer a silent computing environment. However, it lacks advanced cooling technologies.

Conversely, the Lian Li SP850 V2 Gold is equipped with a premium 92mm Fluid Dynamic Bearing fan, specifically engineered for efficient and quiet thermal performance. This design not only reduces noise levels but also enhances the overall longevity of the unit. As a result, while both units are designed with low noise in mind, the Lian Li model offers superior technology that ensures quieter operation, especially under load.

Modularity and Connectivity

The MSI MAG A550BN is a non-modular power supply, which means that all cables are fixed. This design can lead to cable clutter within the case, potentially obstructing airflow and making cable management more challenging. While it may suffice for simpler builds, it lacks the flexibility needed for more complex systems.

In contrast, the Lian Li SP850 V2 Gold features a fully modular design, allowing users to connect only the cables they need for their specific build. This not only reduces clutter but also enhances airflow, thereby improving overall cooling efficiency. Additionally, the inclusion of a two-tone 12V-2x6 power cable with visual cues further simplifies connections for high-performance components. In terms of modularity and ease of installation, the Lian Li model offers significant advantages over the MSI unit.

Value for Money

In terms of cost, the MSI MAG A550BN is much more affordable at C$84.99, making it an attractive option for users on a budget. It provides decent performance and reliability for basic builds, appealing to those who may not require high wattage or advanced features.

Conversely, the Lian Li SP850 V2 Gold, priced at C$194.23, represents a higher investment. However, it offers enhanced performance, modularity, and a longer warranty, catering to power users and gamers looking for a robust power supply. While the MSI MAG A550BN is a great value for money in its category, the Lian Li model justifies its premium price with superior features and performance, making it a worthy investment for serious builds.

Which should you buy?

Choosing between the MSI MAG A550BN and the Lian Li SP850 V2 Gold ultimately depends on your specific needs and budget. If you're building a basic system and want an affordable option, the MSI MAG A550BN at C$84.99 provides reliable performance without breaking the bank. However, for users looking to invest in a high-performance system with future-proofing capabilities, the Lian Li SP850 V2 Gold at C$194.23 is the better choice due to its higher wattage, modular design, extended warranty, and superior cooling capabilities.
