Gigabyte UD850GM PG5 ICE 80 Plus Gold Fully Modular 850w PCIe 5.0 White Power Su vs Seasonic Prime TX-1600 Noctua Edition

Price Comparison

The Gigabyte UD850GM PG5 ICE is priced at £99.61, whereas the Seasonic Prime TX-1600 Noctua Edition comes in at a significantly higher price of £429.00. This stark difference of £329.39 highlights the budget-friendly nature of the Gigabyte model, making it an attractive option for users looking for a high-quality power supply without breaking the bank. On the other hand, the Seasonic's premium pricing reflects its high-end features and performance, tailored for more demanding setups.

Power Efficiency

The Gigabyte UD850GM PG5 ICE is 80 PLUS Gold certified, indicating a high level of efficiency in power usage, but it does not reach the efficiency level of the Seasonic Prime TX-1600 Noctua Edition, which is certified at the 80 PLUS Titanium level. The Seasonic unit boasts an impressive 94% efficiency at 50% load, ensuring minimal waste heat and lower power consumption. This superior efficiency can lead to reduced electricity bills over time, making the Seasonic a potentially more economical choice in the long run for energy-conscious users.

Noise Levels

When it comes to operational noise, the Seasonic Prime TX-1600 Noctua Edition stands out with its ultra-quiet Noctua NF-A12x25 fan, which is designed to operate at levels approximately 8-10 dB(A) quieter than the standard model. This makes the Seasonic ideal for users who favour a silent computing environment. In contrast, the Gigabyte UD850GM PG5 ICE features a 120mm smart hydraulic bearing fan but does not specify noise levels, suggesting it may not be as quiet as the Noctua-enhanced Seasonic.

Modular Design

Both power supplies offer fully modular designs, allowing users to customise their cable management for optimal airflow and aesthetics. The Gigabyte UD850GM PG5 ICE promotes a clean setup with its compact size, while the Seasonic Prime TX-1600 Noctua Edition features Noctua-themed cabling, enhancing the visual appeal of high-end builds. This modularity is beneficial for users who wish to minimise cable clutter and improve overall system airflow, making both products suitable for a tidy PC environment.

Compatibility

The Gigabyte UD850GM PG5 ICE is Intel ATX 3.1 and PCIe Gen 5.1 ready, ensuring compatibility with the latest hardware. The Seasonic Prime TX-1600 Noctua Edition also meets these standards and includes a 12V-2×6 connector specifically for powering high-end graphics cards like the NVIDIA GeForce RTX 4090 series. This makes the Seasonic particularly advantageous for users planning to build or upgrade to cutting-edge gaming or workstation setups, as it provides a robust solution for future-proofing their systems.

Cooling Solutions

Both units incorporate advanced cooling solutions to maintain optimal thermal performance. The Gigabyte UD850GM PG5 ICE features a 120mm smart hydraulic bearing fan, while the Seasonic Prime TX-1600 Noctua Edition employs a specially designed, highly optimised fan grill to reduce noise levels and improve airflow. The Seasonic's semi-passive operation allows the fan to remain off until 50% load, which further enhances its quiet operation. This difference in cooling strategies may appeal to users prioritising either performance or silence in their builds.

Protection Features

In terms of safety and reliability, the Gigabyte UD850GM PG5 ICE includes multiple protection features such as OVP (Over Voltage Protection), OPP (Over Power Protection), SCP (Short Circuit Protection), UVP (Under Voltage Protection), OCP (Over Current Protection), and OTP (Over Temperature Protection). The Seasonic Prime TX-1600 Noctua Edition also boasts robust protection mechanisms, ensuring steadfast power delivery and highly regulated voltage. This makes both models reliable choices for safeguarding sensitive components, although the comprehensive protections of the Gigabyte model may appeal to users prioritising safety.

Which should you buy?

In conclusion, the choice between the Gigabyte UD850GM PG5 ICE and the Seasonic Prime TX-1600 Noctua Edition largely depends on your specific needs and budget. The Gigabyte model is an excellent choice for users seeking a cost-effective, efficient, and reliable power supply for gaming or general use, priced at £99.61. Conversely, the Seasonic Prime TX-1600 Noctua Edition, with its premium features, ultra-quiet operation, and exceptional power efficiency at £429.00, is better suited for high-end builds where performance and silence are paramount. Ultimately, your decision should consider both your performance requirements and financial constraints.
