ASUS ROG Strix 1200W Platinum vs NZXT C850 Gold Core - 850W ATX 3.1 Power Supply -

Price Comparison

The ASUS ROG Strix 1200W Platinum is priced at $264.99, while the NZXT C850 Gold Core comes in significantly lower at $99.99, making it about 62% cheaper. This substantial price difference makes the NZXT a more attractive option for budget-conscious consumers or those looking to save on power supply costs. However, the higher price of the ASUS ROG Strix reflects its premium features and capabilities, appealing to high-performance gaming setups. Ultimately, the choice comes down to what features are deemed necessary for your specific needs.

Power Output

The ASUS ROG Strix offers a robust 1200W power output, suitable for high-end gaming rigs and multiple graphics cards. In contrast, the NZXT C850 Gold Core provides 850W, which is adequate for most single-GPU systems and mid-range builds. The difference in wattage means that the ASUS power supply can support more demanding setups, allowing for future upgrades. If you plan on running multiple high-performance components, the ROG Strix will serve you better, but for standard gaming needs, the NZXT's output is often sufficient.

Efficiency Ratings

Efficiency is crucial when evaluating power supplies, as it affects both performance and electricity costs. The ASUS ROG Strix is 80 Plus Platinum certified, indicating superior efficiency in converting AC to DC power and minimizing wasted energy. Meanwhile, the NZXT C850 Gold Core holds an 80 Plus Gold certification, which is still excellent but slightly less efficient than its platinum counterpart. The difference in efficiency could translate to lower electricity bills over time for the ASUS, especially under heavy use, which is an essential consideration for long-term gamers.

Features and Technology

In terms of technology, the ASUS ROG Strix boasts a GaN MOSFET design, which enhances power efficiency by up to 30%. It also features a "GPU-First" intelligent voltage stabilizer that improves voltage delivery by up to 45% to your graphics card, ensuring smoother gameplay. On the other hand, the NZXT C850 Gold Core offers Cybenetics Platinum efficiency and a zero RPM fan mode for whisper-quiet operation during light workloads. While both power supplies come with advanced features, the ASUS's focus on optimizing power for gaming performance gives it an edge in specialized scenarios.

Build Quality and Warranty

The build quality of both power supplies is commendable, but they cater to different priorities. The ASUS ROG Strix includes large heatsinks and dual ball fan bearings, promising lower temperatures and longer lifespan compared to sleeve bearings. Additionally, it comes with a generous 10-year warranty. Conversely, the NZXT C850 is backed by a 7-year warranty, which, while still substantial, is shorter than that of the ASUS. The longer warranty period of the ROG Strix indicates a higher confidence in its durability and reliability, making it a better choice for long-term investments.

Noise Levels

Noise levels are an important consideration for many users, particularly for those who prefer quieter systems. The NZXT C850 Gold Core is specifically designed for near-silent operation, earning a Cybenetics A++ rating for its noise levels. It features a fluid dynamic bearing fan that operates in zero RPM mode under low loads, ensuring that noise remains minimal. In contrast, while the ASUS ROG Strix employs 0dB technology for silent light gaming, it may still generate more noise under heavier loads compared to the near-silent operation of the NZXT. If maintaining a quiet environment is a priority, the NZXT could be the better option.

Compatibility and Future-Proofing

Both power supplies are designed to be compatible with next-gen GPUs, but they differ in their specifications. The ASUS ROG Strix features a native 12V-2x6 connector for PCIe 5.0, ensuring it can handle the latest graphics cards without issue. Meanwhile, the NZXT C850 Gold Core also supports PCIe 5.1 with its dual-color 12V-2x6 connector, making it suitable for modern systems as well. While both are future-proof to an extent, the higher wattage and advanced features of the ASUS may better accommodate future upgrades, particularly for high-performance gaming setups.

Which should you buy?

Choosing between the ASUS ROG Strix 1200W Platinum and the NZXT C850 Gold Core ultimately depends on your specific needs and budget. The ASUS ROG Strix is an excellent choice for gamers seeking top-tier performance, advanced features, and a longer warranty, but it comes at a premium price of $264.99. In contrast, the NZXT C850 Gold Core, at $99.99, offers solid performance for standard gaming setups with efficient operation and quieter performance. If you’re building a high-end rig, the ASUS may be worth the investment, whereas the NZXT serves well for those seeking quality without breaking the bank.
