MSI MAG A1000GLS PCIE5 Power Supply Unit vs SAMA G850 Power Supply - 850W Fully Modular 80 Plus Gold Certified ATX 3.1 & PCI

Price Comparison

When it comes to price, the SAMA G850 Power Supply is the more affordable option at £84.99, compared to the MSI MAG A1000GLS, which is priced at £104.99. This £20 difference may be significant for budget-conscious consumers looking for a reliable power supply. Both units offer 80 PLUS Gold certification, indicating high energy efficiency, but the SAMA model gives you a competitive edge in pricing while still maintaining quality and performance.

Efficiency Ratings

Both power supplies boast 80 PLUS Gold certification, which signifies high efficiency. The MSI MAG A1000GLS offers up to 90% efficiency, while the SAMA G850 claims up to 91.15% at typical load. This slight edge in efficiency for the SAMA power supply translates into reduced power waste and lower heat generation, which can be crucial for high-performance systems where energy consumption is a key consideration. Therefore, if you’re looking for a power supply that maximises efficiency, the SAMA G850 is the superior choice.

Power Output

The MSI MAG A1000GLS has a maximum power output of 1000W, providing ample headroom for high-performance hardware, including demanding GPUs and CPUs. In contrast, the SAMA G850 offers 850W of output, which is still sufficient for most gaming rigs and workstations. However, if you anticipate future upgrades or plan to run multiple high-powered components, the higher capacity of the MSI MAG A1000GLS could be a decisive factor for you.

Design and Modularity

Both power supplies feature a compact design, measuring 150 mm in length and width, allowing them to fit comfortably in most PC cases. However, the SAMA G850 is fully modular, which means you only use the cables you need, improving cable management and airflow within the case. The MSI model, while also well-designed, does not specify full modularity. For users prioritising a clean build and optimal airflow, the SAMA G850’s fully modular design stands out.

Cooling Solutions

Cooling is an important aspect of power supply performance, and both units have features aimed at maintaining low noise levels. The MSI MAG A1000GLS utilises a 135 mm fluid-dynamic bearing fan, designed for low-noise operation comparable to a peaceful night. Meanwhile, the SAMA G850 is equipped with a 140 mm ECO fan with Fluid Dynamic Bearing, which ensures quiet cooling and an extended lifespan. While both fans are designed to keep noise to a minimum, the SAMA G850’s slightly larger fan may provide better cooling performance.

Compatibility and Connectivity

The MSI MAG A1000GLS is equipped with native 12V-2x6 PCIe connectors, delivering up to 600W specifically for PCIe 5.1 GPUs, making it highly compatible with the latest graphics cards. The SAMA G850 also features a native 12V-2x6 connector, ensuring compatibility with NVIDIA’s latest RTX 50 and 40 series GPUs. Both power supplies are compliant with the latest standards, making them suitable for modern gaming and workstation builds. However, the MSI’s higher overall wattage may offer more flexibility for high-end configurations.

Protection Features

Both power supplies come with a suite of protection features designed to ensure safe operation. The MSI MAG A1000GLS includes OCP, OTP, OPP, SCP, UVP, SIP, and NLO protection, which are essential for preventing damage during extreme conditions. Similarly, the SAMA G850 boasts complete protections including OVP, OCP, OTP, OPP, SCP, and UVP. While both units provide robust safety features, their effectiveness will ultimately depend on the specific conditions and usage scenarios, but they are both reliable options in terms of safety.

Which should you buy?

In determining which power supply to purchase, budget, efficiency, modularity, and future-proofing capabilities should guide your decision. The SAMA G850 Power Supply offers a compelling price point of £84.99 with slightly higher efficiency ratings and a fully modular design, making it a great choice for those looking to keep costs down while still achieving high performance. On the other hand, the MSI MAG A1000GLS, priced at £104.99, provides a higher power output and may be the better option for users planning to build high-performance systems or who require additional capacity for future upgrades. Ultimately, your choice should reflect your specific needs and preferences in terms of performance and budget considerations.
