NZXT C850 SFX Gold - 850W SFX ATX 3.1 Power Supply - 80 Plus Gold - Cybenetics P vs MSI MAG A1000GLS PCIE5 Power Supply Unit

Price Comparison

When considering price, the MSI MAG A1000GLS PCIE5 is more affordable at £104.99 compared to the NZXT C850 SFX Gold, which is priced at £129.98. This represents a difference of £25, making the MSI model a more budget-friendly option for those looking to save while still securing a reliable power supply. The lower price of the MSI unit does not compromise on efficiency, as both products are certified with an 80 PLUS Gold rating, ensuring high efficiency and performance.

Power Output

In terms of power output, both power supplies deliver substantial capabilities for modern systems. The NZXT C850 SFX Gold provides 850W of power, which is well-suited for high-performance builds requiring robust energy supply. On the other hand, the MSI MAG A1000GLS supports up to 1000W but is designed to deliver 600W through its native 12V-2x6 PCIe connectors. This makes both supplies ideal for powering high-demand components such as GPUs and CPUs, though the NZXT has a slight edge in overall wattage.

Design and Form Factor

The NZXT C850 SFX Gold is optimised for compact builds, featuring a small SFX form factor that maximises space efficiency in smaller cases. This is particularly useful for users who are building mini-PCs or have limited space. Conversely, the MSI MAG A1000GLS comes in a standard ATX form factor, measuring 150 mm in length and width, which may provide easier installation in larger cases. However, it is designed to fit comfortably in most PC cases, allowing for better cable management and airflow.

Efficiency Ratings

Both power supplies boast impressive efficiency ratings, with each receiving an 80 PLUS Gold certification. This ensures that both units operate at up to 90% efficiency under typical loads, translating to lower energy costs and reduced heat output. The NZXT C850 SFX Gold further enhances its efficiency with a Cybenetics Platinum rating, suggesting superior performance in reducing heat output. The MSI’s efficiency is also commendable, making both options excellent choices for energy-conscious consumers.

Noise Levels

When it comes to noise levels, both power supplies are engineered for low-noise operation. The NZXT C850 SFX Gold features a 92 mm fluid dynamic bearing (FDB) fan that ensures quiet operation, especially with its Zero RPM mode for silent cooling at lower loads. The MSI MAG A1000GLS, equipped with a 135 mm FDB fan, also maintains a low sound level, comparable to a peaceful night. This makes both units suitable for users who prioritise a quiet computing experience.

Cooling Solutions

Cooling solutions are critical for maintaining performance and longevity in power supplies. The NZXT C850 SFX Gold employs a 92 mm FDB fan that is designed for silent operation and efficient cooling. Additionally, it offers features like low ripple noise and tight voltage regulation, which contribute to overall system stability. The MSI MAG A1000GLS, with its larger 135 mm FDB fan, enhances durability and ensures effective cooling, making it equally competent at managing heat during intensive tasks.

Compatibility with Modern Hardware

The NZXT C850 SFX Gold is ATX 3.1 certified, which makes it suitable for the latest graphics cards, providing reliable GPU power through its 600W 12V-2x6 connector. This certification ensures that it meets the energy demands of modern hardware. Similarly, the MSI MAG A1000GLS is also equipped with native 12V-2x6 connectors, supporting PCIe 5.1 GPUs, making it a robust choice for cutting-edge builds. Both power supplies are well-suited for gamers and professionals utilising the latest technology.

Which should you buy?

Choosing between the NZXT C850 SFX Gold and the MSI MAG A1000GLS ultimately depends on your specific needs and budget. If you require a compact power supply that maximises space and offers slightly higher overall power, the NZXT model is an excellent investment. However, if you are looking for a more cost-effective solution without sacrificing performance, the MSI power supply is a compelling choice, especially considering its lower price of £104.99. Both units provide reliable performance and efficiency, making either choice suitable for modern builds.
