CORSAIR RM850e vs Lian Li SP850 V2 Gold 850 Watt SFX Form Factor Power Supply

Price Comparison

The CORSAIR RM850e is priced at C$184.99, while the Lian Li SP850 V2 Gold is slightly more expensive at C$194.23. The cost difference of C$9.24 may seem minimal, but it can influence budget-conscious buyers. Given that both power supplies offer similar wattage at 850 watts, the price can be a deciding factor for those looking to maximize value without compromising on quality.

Modular Design

Both power supplies are fully modular, allowing users to connect only the cables necessary for their systems. This feature not only helps reduce cable clutter but also enhances airflow within the case, leading to improved cooling performance. The CORSAIR RM850e touts its reliability and low-noise operation, while the Lian Li SP850 V2 Gold also emphasizes efficiency and quirk-free performance. The modular designs of both units are ideal for users looking to build a clean and efficient setup.

Certification Standards

The CORSAIR RM850e and Lian Li SP850 V2 Gold both boast ATX 3.1 certification, ensuring they meet the latest power standards. This certification is crucial for modern systems, especially those with high-performance graphics cards requiring stable power delivery. The CORSAIR unit supports PCIe 5.1, while the Lian Li version is compatible with PCIe Gen 5.0. The difference in compatibility may be relevant for users with cutting-edge components, although both units are equipped to handle transient power demands effectively.

Cooling Solutions

Cooling is a critical factor in power supply performance. The CORSAIR RM850e features a 120mm rifle bearing fan designed to minimize noise, even under full load. In contrast, the Lian Li SP850 V2 Gold utilises a 92mm Fluid Dynamic Bearing (FDB) fan for efficient and quiet thermal management. While both cooling solutions aim to reduce operational noise, the larger fan in the CORSAIR model may offer better airflow capabilities. This difference could be significant for users operating in noise-sensitive environments.

Capacitors and Electrical Performance

The CORSAIR RM850e is built with 105°C-rated capacitors, which are known for their reliability and performance under stress. On the other hand, the Lian Li SP850 V2 Gold employs high-quality Japanese electrolytic capacitors that are integral for stable and dependable power delivery. Both units focus on providing reliable electrical performance, but the choice of capacitor may appeal differently to users depending on their specific needs and preferences in terms of brand reputation and engineering.

Standby Power Features

Standby power capabilities play a significant role in modern power supplies. The Lian Li SP850 V2 Gold features an upgraded 5VSB rail that increases its current capacity from 2.5A to 3A, which is beneficial for supporting today's power-hungry peripherals. The CORSAIR RM850e, while modern standby compatible, does not specify its standby current capacity. This enhancement in the Lian Li model may offer an edge for users needing reliable power for devices in standby mode, making it particularly useful for gamers or content creators who use peripherals that demand consistent power.

Size and Form Factor

The Lian Li SP850 V2 Gold is specifically designed to meet the ≤63.5mm SFX size specification, making it an excellent choice for compact builds. The CORSAIR RM850e does not specify its size in the provided data, but it is typically designed for standard ATX cases. For users prioritizing space-saving solutions in smaller cases, the Lian Li model may be the better option. This form factor consideration is increasingly important as more builders opt for compact setups.

Which should you buy?

Choosing between the CORSAIR RM850e and the Lian Li SP850 V2 Gold ultimately depends on your specific needs and preferences. If you're looking for a more budget-friendly option with a larger cooling fan, the CORSAIR RM850e at C$184.99 might be the ideal choice. However, if you require advanced standby power capabilities and a compact design, the Lian Li SP850 V2 Gold at C$194.23 offers significant advantages worth the extra cost. Both power supplies are high-quality options, so your decision should align with your build requirements and personal preferences.
