NZXT C850 Gold ATX 3.1 - Fully Modular Low-Noise PC Gaming Power Supply - 850 Wa vs Asus ROG Strix 1200W Platinum PSU

Overview of the NZXT C850 Gold and Asus ROG Strix 1200W Platinum PSUs

The NZXT C850 Gold and the Asus ROG Strix 1200W Platinum are both high-performance power supplies, but they cater to different segments of the gaming market. The NZXT C850 Gold is priced at £84.90 and offers an 850W output, while the Asus ROG Strix 1200W Platinum, at £179.99, provides a more robust 1200W. This price difference reflects their target audiences and intended use cases, with the NZXT model being more budget-friendly and the Asus model designed for enthusiasts requiring higher power delivery.

Power Output Comparison

The most noticeable difference between the NZXT C850 Gold and the Asus ROG Strix 1200W Platinum is their power output. The NZXT C850 Gold delivers 850 watts, which is ample for most high-performance gaming builds. However, the Asus ROG Strix significantly exceeds this with a maximum output of 1200 watts, making it suitable for extreme gaming setups that include high-end components such as multiple graphics cards or extensive cooling solutions. This power surplus ensures that users can push their systems without worrying about power constraints.

Efficiency Ratings

Efficiency is a key consideration for power supplies, and both the NZXT C850 Gold and Asus ROG Strix 1200W Platinum exhibit high-performance ratings. While the NZXT C850 Gold is compliant with the ATX 3.1 standard, which ensures stability and efficiency, the Asus ROG Strix boasts a Platinum certification. This certification indicates that the ROG model operates with superior efficiency, reducing wasted energy by up to 30% due to its GaN MOSFET technology. This difference not only impacts energy consumption but also translates to lower electricity bills over time, making the ROG Strix an attractive option for prolonged usage.

Noise Levels and Cooling Solutions

When it comes to noise levels, the NZXT C850 Gold features an ultra-low noise fan that remains silent under 50% load, ensuring a quiet gaming environment. In contrast, the Asus ROG Strix employs advanced cooling solutions, including large heatsinks and dual ball fan bearings that enhance cooling efficiency while reducing noise. Both power supplies incorporate technologies that cater to quieter operations, but the NZXT C850 Gold’s Zero Fan Mode may appeal more to users who prioritise silence during light workloads, while the ROG Strix’s robust cooling design is ideal for high-performance scenarios.

Build Quality and Component Selection

The build quality of both power supplies reflects their intended markets. The NZXT C850 Gold uses 100% premium Japanese capacitors, which improve hold-up time and reduce ripple noise, contributing to reliable power delivery. On the other hand, the Asus ROG Strix 1200W Platinum features a more intricate internal layout aided by GaN technology, which not only enhances efficiency but also allows for cooler operation. The focus on high-quality components in both models suggests that they will perform well over time, but the ROG Strix’s emphasis on premium materials indicates a potential for longevity under high loads.

Connectivity Options

Both the NZXT C850 Gold and the Asus ROG Strix 1200W Platinum offer fully modular designs, allowing users to connect only the cables they need, thus promoting a clean build. However, the Asus model stands out with its GPU-FIRST voltage sensing technology, which enhances voltage delivery to the graphics card by up to 45%. This feature is particularly beneficial for gamers looking to maximise performance. The NZXT C850 Gold is also prepared for high-performance components, being compatible with NVIDIA GeForce RTX 50 Series graphics cards, but it does not feature the same level of voltage optimisation as the ROG Strix.

Pricing and Value Proposition

There is a significant price difference between the two power supplies, with the NZXT C850 Gold retailing at £84.90 and the Asus ROG Strix 1200W Platinum priced at £179.99. The NZXT model offers a compelling value for gamers on a budget or those with mid-range setups, while the Asus model justifies its higher cost with enhanced features and capabilities, particularly for high-end users who demand maximum performance and efficiency. The choice ultimately boils down to the user's specific needs and budgetary constraints.

Which should you buy?

Choosing between the NZXT C850 Gold and the Asus ROG Strix 1200W Platinum ultimately depends on your gaming needs and budget. If you are a gamer seeking a reliable power supply for a mid-range system at an attractive price of £84.90, the NZXT C850 Gold is an excellent choice. However, if you are an enthusiast with a high-performance setup that demands superior power delivery and efficiency, the Asus ROG Strix 1200W Platinum, despite its higher price of £179.99, offers features that can significantly enhance your gaming experience.
