NZXT C850 SFX Gold - 850W SFX ATX 3.1 Power Supply - 80 Plus Gold - Cybenetics P vs MSI MPG A1000G PCIE5 Power Supply Unit

Price Comparison

The NZXT C850 SFX Gold is priced at £129.98, while the MSI MPG A1000G PCIE5 is more affordable at £104.99. This price difference of £25.00 may influence budget-conscious consumers. The MSI unit offers an appealing option for those looking to save on their power supply without sacrificing key features. However, the higher price of the NZXT unit is reflective of its specific features tailored for compact builds and its certification ratings. Depending on your budget, the MSI could be a more attractive choice, especially for users who do not require the additional benefits that the NZXT offers.

Design and Form Factor

The NZXT C850 SFX Gold is designed specifically for compact builds with its SFX form factor. This optimises space efficiency while still delivering full power capabilities, making it a prime choice for small form factor (SFF) cases. In contrast, the MSI MPG A1000G PCIE5 adheres to the ATX 3.0 standard, which allows for more flexibility in larger cases. The full modular design of the MSI power supply includes flat black cables that help reduce clutter, improving airflow inside the case. While both designs have their merits, the choice ultimately depends on the size of your build and whether you prioritise compactness or modular flexibility.

Efficiency Ratings

The NZXT C850 SFX Gold boasts an 80 PLUS Gold efficiency rating, indicating that it operates at up to 90% efficiency under typical loads. This high efficiency not only reduces energy consumption but also lowers thermal output, contributing to a quieter operation thanks to its Cybenetics A- noise rating. The MSI MPG A1000G PCIE5 also carries an 80 PLUS Gold certification, highlighting its ability to efficiently handle power-hungry hardware like high-end graphics cards. Both units are designed to minimise energy waste, which is crucial for gamers and creators alike, making them both excellent choices for efficient energy use.

Cooling Mechanism

The NZXT C850 SFX Gold features a 92 mm fluid dynamic bearing (FDB) fan with a Zero RPM mode that activates when the load is low, ensuring silent operation during less intense tasks. This is particularly beneficial for users who prioritise a quiet computing experience. On the other hand, the MSI MPG A1000G PCIE5 utilises a 135 mm FDB fan that also includes a 0% RPM mode to deactivate the fan when the thermal design power (TDP) is below 40%. While both cooling solutions aim to enhance efficiency and reduce noise, the choice between them may depend on the user's specific noise sensitivity and thermal management preferences.

Power Delivery and Compatibility

The NZXT C850 SFX Gold has a notable feature in its ATX 3.1 certification and a 600W 12V-2x6 connector, ensuring reliable power delivery for modern graphics cards. This is particularly important as graphical demands increase in contemporary gaming and rendering. Alternatively, the MSI MPG A1000G PCIE5 supports PCIe 5.0 GPUs with a native 16-pin (12VHPWR) connector capable of providing up to 600W of power. This makes it suitable for the latest high-performance graphics cards from both NVIDIA and AMD. Users will need to consider which specific power delivery features align best with their hardware requirements and future upgrade plans.

Build Quality and Warranty

The NZXT C850 SFX Gold is designed with low ripple noise and tight voltage regulation, contributing to overall system stability. This is complemented by its focus on quiet operation with a premium quality FDB fan. However, the MSI MPG A1000G PCIE5’s robust design includes a half-bridge LLC with a DC-to-DC converter and active PFC, ensuring reliable output and longevity. Moreover, it features Japanese 105°C capacitors for optimal stability and comes with an impressive 10-year warranty, which can offer peace of mind for long-term use. While both power supplies aim for durability, the warranty and build quality of the MSI may appeal to those looking for reassurance in their investment.

User Experience and Installation

Installation ease can vary between the two models. The NZXT C850 SFX Gold is compact and designed for SFF cases, which may present challenges in space-constrained environments. Its orientation is crucial for optimal airflow and efficient cable management. The MSI MPG A1000G PCIE5, being fully modular, allows users to connect only the cables they need, potentially simplifying the installation process and improving airflow within the case. This modularity can be particularly beneficial for users who frequently upgrade or modify their systems. Ultimately, user experience may hinge on the specific build and personal preferences regarding cable management and space.

Which should you buy?

Choosing between the NZXT C850 SFX Gold and the MSI MPG A1000G PCIE5 ultimately comes down to your specific needs and budget. The NZXT unit is ideal for compact builds and offers features that support high-efficiency operation and quiet performance, albeit at a higher price point of £129.98. Conversely, the MSI MPG A1000G PCIE5 provides excellent value at £104.99, with robust power delivery and a modular design that facilitates easier installation in larger cases. If budget is a primary concern and you desire a power supply suited for the latest GPUs, the MSI is a strong contender. However, for those prioritising compactness and premium efficiency, the NZXT may be worth the investment.
