Dimension comparison
Overview
In the realm of power supplies, the Cooler Master V850 SFX Gold and the Asus ROG Strix 1200W Platinum PSU stand out as two compelling options, each catering to distinct user needs. Priced at £134.56, the Cooler Master focuses on compact efficiency for small form factor builds, while the Asus, at £179.99, aims to deliver exceptional power for high-performance gaming systems.
Design and Build Quality
The Cooler Master V850 SFX Gold is engineered specifically for small form factor mini-ITX cases, boasting compact dimensions of 100 x 125 x 63.5 mm. This design allows it to fit seamlessly into tight spaces, while the included SFX-to-ATX bracket ensures compatibility with larger cases as well. In contrast, the Asus ROG Strix 1200W Platinum utilises a more robust design, incorporating GaN MOSFET technology which enhances power efficiency and promotes a cooler internal layout. The inclusion of large ROG heatsinks is aimed at reducing temperatures and noise, making it suitable for high-demand environments.
Efficiency and Performance
The Cooler Master V850 SFX Gold achieves an impressive 80 PLUS Gold certification, indicating a minimum efficiency of 90% under typical load conditions. This level of efficiency not only saves on power costs but also reduces heat accumulation, which is essential in compact builds. On the other hand, the Asus ROG Strix 1200W Platinum takes efficiency a step further with its GaN technology, claiming up to 30% superior power efficiency compared to traditional designs. This enhanced efficiency results in better performance, particularly for high-end graphics cards, where voltage delivery can be improved by up to 45%.
Cooling Solutions
A standout feature of the Cooler Master V850 SFX Gold is its quiet operation, facilitated by a 92mm fluid dynamic bearing fan that ensures low noise levels during operation. Additionally, it includes a semi-fanless mode, allowing the PSU to operate silently under light loads. In comparison, the Asus ROG Strix 1200W Platinum also prioritises cooling, featuring dual ball fan bearings that can last up to twice as long as traditional sleeve bearings. Its 0dB technology allows for silent operation during light gaming, making it a strong competitor in noise reduction.
Cable Management
The Cooler Master V850 SFX Gold excels in cable management with fully modular cabling, including a variety of connectors such as ATX 24 Pin, EPS, and PCI-e options. This feature is particularly beneficial for users looking to optimise airflow within their builds by eliminating unnecessary cables. The Asus ROG Strix 1200W Platinum does not specify its modularity, but its focus on internal organisation through GaN technology suggests an effort to maintain a tidy and efficient setup. However, without explicit details on cable management, the Cooler Master holds an advantage in this area.
Warranty and Longevity
When it comes to warranty, the Cooler Master V850 SFX Gold offers a generous 10-year standard warranty, reflecting confidence in its long-term reliability and performance. This warranty covers the PSU against defects, providing peace of mind for users. The Asus ROG Strix 1200W Platinum does not specify its warranty duration in the provided data, which might raise concerns for potential buyers who prioritise long-term support and durability in their components.
Target Audience
The Cooler Master V850 SFX Gold is tailored for users who require a powerful yet compact PSU for small form factor builds, making it ideal for mini-ITX gaming rigs or office PCs. Its affordable price point of £134.56 further sweetens the deal for budget-conscious builders. Conversely, the Asus ROG Strix 1200W Platinum is designed for enthusiasts and gamers who demand high performance and are willing to invest in superior technology, as evidenced by its price of £179.99. Its features make it particularly appealing for high-end gaming setups where power delivery and thermal efficiency are critical.
Which should you buy?
Choosing between the Cooler Master V850 SFX Gold and the Asus ROG Strix 1200W Platinum boils down to specific needs and budget. If you require a compact, efficient power supply for a small form factor build and appreciate superior cable management, the Cooler Master at £134.56 is the clear choice. However, if your focus is on maximising performance for high-demand gaming applications and you’re willing to invest more for advanced technology, the Asus ROG Strix 1200W Platinum, priced at £179.99, may be the better option. Ultimately, understanding your requirements will guide you to the right decision.
