Cooler Master V850 SFX Gold vs Gigabyte UD850GM PG5 ICE 80 Plus Gold Fully Modular 850w PCIe 5.0 White Power Su

Price Comparison

The Cooler Master V850 SFX Gold is priced at £134.56, while the Gigabyte UD850GM PG5 ICE comes in at £99.61. This significant price difference of £34.95 may influence your purchasing decision, particularly if budget constraints are a concern.

While both power supplies are 80 PLUS Gold certified, indicating high energy efficiency, the Cooler Master offers a compact design tailored for small form factor builds, which might justify its higher price for users needing a specific form factor. Conversely, Gigabyte's more affordable model still provides essential features, making it an attractive option for those seeking a balance of performance and cost.

Design and Form Factor

The Cooler Master V850 SFX Gold is specifically designed for small form factor (SFF) mini-ITX PC cases, measuring 100 x 125 x 63.5 mm. Its compact dimensions cater to users who prioritise space-saving builds. In contrast, the Gigabyte UD850GM PG5 ICE offers a more traditional ATX size but maintains a compact design, making it versatile for various case configurations.

While the Cooler Master model can be adapted to ATX cases with a complementary bracket, the Gigabyte model’s form factor allows it to fit into a broader range of cases without additional components. This difference in design and intended use can significantly impact your decision based on your specific build requirements.

Modular Cabling

Both power supplies feature fully modular designs, allowing for optimal cable management. The Cooler Master V850 SFX Gold comes with a comprehensive set of cables, including ATX 24 Pin, EPS 4+4, and multiple PCI-e connectors, facilitating sophisticated and clean builds.

On the other hand, the Gigabyte UD850GM PG5 ICE also embraces a fully modular approach, which aids in reducing clutter and enhancing airflow within the case. The ability to connect only the necessary cables ensures that both power supplies cater to users who value a tidy and efficient setup, but the Cooler Master's broader cable offering may be more beneficial for complex builds.

Cooling Solutions

The Cooler Master V850 SFX Gold employs a 92mm fluid dynamic bearing fan, which is designed to keep noise levels and temperatures low, even under load. It also features a semi-fanless mode that activates when the PSU operates under 15% load, enhancing quiet operation during low-demand tasks.

Conversely, the Gigabyte UD850GM PG5 ICE utilises a larger 120mm smart hydraulic bearing fan. This fan is optimised for thermal performance, ensuring effective cooling even during high-performance use. The choice of fan size and technology can influence noise levels and cooling efficiency, making it essential to consider your system's cooling requirements and noise tolerance.

Efficiency and Performance

Both power supplies are 80 PLUS Gold certified, signifying an efficiency level of up to 90% under typical load conditions. This certification ensures that users can expect lower electricity bills and reduced heat generation during operation.

While both models excel in energy efficiency, the Cooler Master’s design is specifically aimed at compact systems with high energy demands, optimising performance in smaller builds. In contrast, the Gigabyte PSU's single +12V rail is designed to deliver stable power to high-performance components, making it suitable for a wide range of systems, from gaming rigs to workstations.

Component Quality

The Cooler Master V850 SFX Gold is built with high-quality components, boasting 100% Japanese capacitors, which are known for their reliability and longevity. This robust construction is backed by a 10-year warranty, ensuring peace of mind for users looking for a durable power supply.

Similarly, the Gigabyte UD850GM PG5 ICE also features 100% Japanese capacitors, indicating a commitment to quality. However, it does not explicitly state the warranty duration. The emphasis on reliable components in both models suggests that users can expect long-term performance, but the extended warranty of the Cooler Master may sway those prioritising durability.

Protection Features

Protection features are critical in power supply units to safeguard both the unit and connected components. The Cooler Master V850 SFX Gold offers a range of protective measures, although specific details are not provided in the data.

In comparison, the Gigabyte UD850GM PG5 ICE is explicitly equipped with multiple protection mechanisms, including Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), Over Current Protection (OCP), and Over Temperature Protection (OTP). These features provide a comprehensive safety net, making it a compelling option for users who want additional security for their high-performance systems.

Which should you buy?

Choosing between the Cooler Master V850 SFX Gold and the Gigabyte UD850GM PG5 ICE ultimately depends on your specific needs and build requirements. If you are looking for a compact power supply designed for small form factor builds with a longer warranty and superior cooling features, the Cooler Master may be the better choice despite its higher price of £134.56.

However, if budget is a significant factor and you require a reliable, fully modular PSU that is versatile enough for various builds, the Gigabyte UD850GM PG5 ICE at £99.61 presents an excellent value with solid performance and extensive protection features. Consider your priorities, whether they lean towards compactness, price, or a balance of both, to make the best decision for your system.
