Asus ROG Strix 1200W Platinum PSU vs Gigabyte UD850GM PG5 ICE 80 Plus Gold Fully Modular 850w PCIe 5.0 White Power Su

Price Comparison

When it comes to price, the Gigabyte UD850GM PG5 ICE is significantly more affordable at £99.61, compared to the Asus ROG Strix 1200W Platinum PSU, which is priced at £179.99. This notable difference of £80.38 positions the Gigabyte model as a budget-friendly option for those looking for a reliable power supply without breaking the bank. The Asus model, while more expensive, offers advanced features that might justify the higher price for power users looking for top-tier performance.

Power Output

In terms of power output, the Asus ROG Strix 1200W Platinum PSU boasts a remarkable capacity of 1200 watts, making it suitable for high-performance gaming rigs and demanding applications. On the other hand, the Gigabyte UD850GM PG5 ICE offers a solid 850 watts, which is still adequate for most gaming and productivity systems. The additional 350 watts from the Asus unit might be crucial for users who need to power multiple high-end graphics cards or extensive peripheral setups, giving it a distinct advantage in power-hungry scenarios.

Efficiency Ratings

The efficiency ratings of these power supplies highlight their performance capabilities. The Asus ROG Strix model holds a Platinum certification, indicating superior efficiency, while the Gigabyte UD850GM PG5 ICE is certified 80 PLUS Gold. The difference in efficiency can be significant; Platinum-rated units typically deliver up to 90% efficiency or more under typical loads, compared to around 87% for Gold-rated units. This means that the Asus PSU not only runs more efficiently but also generates less heat and consumes less power over time, which could translate into savings on electricity bills for high usage.

Design and Modularity

The design and build quality differ notably between the two products. The Gigabyte UD850GM PG5 ICE features a fully modular design, allowing for a cleaner build and easier cable management, which is especially beneficial in compact cases. In contrast, the Asus ROG Strix 1200W Platinum PSU is designed with large heatsinks and innovative internal layouts to ensure cooler operation. While both have their merits, the fully modular feature of the Gigabyte model can appeal to users who prioritise an organised and efficient setup.

Cooling Solutions

Cooling solutions are critical for maintaining performance and longevity in power supplies. The Asus ROG Strix 1200W Platinum PSU incorporates dual ball fan bearings, which can last up to twice as long as standard sleeve bearings. This contributes to reduced noise levels and improved durability. The Gigabyte UD850GM PG5 ICE, however, utilises a 120mm smart hydraulic bearing fan, which also optimises thermal performance. While both units are designed to manage heat effectively, the superior longevity of the Asus fan could provide an edge in long-term reliability.

Protection Features

Protection features are essential in safeguarding your components. The Gigabyte UD850GM PG5 ICE includes multiple protection mechanisms, such as Over Voltage Protection (OVP), Over Power Protection (OPP), and Short Circuit Protection (SCP), ensuring comprehensive safety for your system. Meanwhile, the Asus ROG Strix 1200W Platinum PSU focuses on delivering stable voltage with its patented intelligent voltage stabiliser, enhancing voltage delivery by up to 45% to your graphics card. Both power supplies offer robust protections, but the range of features in the Gigabyte model may appeal more to users concerned about potential electrical issues.

Brand Reputation and Warranty

Brand reputation can heavily influence purchasing decisions. Asus is well-known in the gaming community for its high-performance products, while Gigabyte has built a solid reputation for reliability and value. The Asus ROG Strix line, in particular, is celebrated for its performance and premium build quality. Gigabyte, meanwhile, emphasises durability and efficiency in its offerings. Both brands typically offer competitive warranties, but checking specific terms may be beneficial, especially for high-investment components like power supplies.

Which should you buy?

Ultimately, the decision comes down to your specific needs and system requirements. If you seek maximum power output and efficiency, the Asus ROG Strix 1200W Platinum PSU is the superior choice, albeit at a higher cost. However, for users on a budget or with less demanding power needs, the Gigabyte UD850GM PG5 ICE provides excellent value with its effective performance and modular design. Consider your long-term power demands and budget constraints to determine which power supply aligns best with your setup.
