CORSAIR HX1500i vs NZXT C850 SFX Gold - 850W SFX ATX 3.1 Power Supply - 80 Plus Gold - Cybenetics P

Pricing Comparison

When it comes to pricing, the CORSAIR HX1500i is significantly more expensive than the NZXT C850 SFX Gold. The HX1500i is priced at £229.00, while the C850 SFX Gold retails for £129.98. This represents a difference of £99.02, making the NZXT option a more budget-friendly choice for consumers looking for a reliable power supply. For those who are building a cost-effective system or working within a limited budget, the NZXT C850 SFX Gold presents a compelling alternative without compromising on essential features.

Power Output and Efficiency

In terms of power output, the CORSAIR HX1500i boasts an impressive 1500W capacity, making it suitable for high-end systems with multiple graphics cards or demanding components. The NZXT C850 SFX Gold, on the other hand, provides 850W of power, which is also ample for most gaming and productivity setups. Despite the lower wattage, the C850 SFX Gold maintains a premium efficiency rating, achieving 80 PLUS Gold status, while the HX1500i offers similar efficiency but does not specify a rating. This suggests that while the HX1500i can support more demanding setups, the C850 SFX Gold is efficient enough for standard builds, reducing electricity costs and heat output.

Form Factor and Design

The form factor of the NZXT C850 SFX Gold is specifically designed for compact builds, optimising space efficiency in small form factor (SFF) cases. In contrast, the CORSAIR HX1500i adheres to the standard ATX size, which may not fit into tighter spaces as easily. This fundamental design difference means that users with limited space should consider the NZXT option, while those with more room can take advantage of the higher power output from the CORSAIR model. The C850 SFX Gold's smaller size does not come at the expense of performance, as it still delivers full-power capabilities.

Cooling Solutions

The cooling solutions of both power supplies prioritise quiet operation, but they differ in fan size and technology. The CORSAIR HX1500i features a robust 140mm Fluid Dynamic Bearing (FDB) fan that allows for extremely quiet performance and long-lasting durability. The NZXT C850 SFX Gold, however, utilises a smaller 92mm FDB fan, which also includes a Zero RPM mode for silent operation. While both fans are designed for quiet performance, the larger fan in the HX1500i may offer superior cooling capabilities under heavy load. Users who value a silent computing experience will appreciate the efforts both brands put into their cooling technologies.

Certification and Reliability

Both the CORSAIR HX1500i and the NZXT C850 SFX Gold are ATX 3.1 certified, ensuring they meet modern power standards and support the latest components. However, the C850 SFX Gold includes a specific 600W 12V-2x6 connector, which is particularly beneficial for reliable GPU power delivery. This added feature can be crucial for users running high-performance graphics cards. Additionally, the NZXT model is noted for its low ripple noise and tight voltage regulation, which help protect components and maintain system stability. This reliability can be a decisive factor for users who prioritise the longevity and stability of their systems.

Software and Customisation

The CORSAIR HX1500i stands out with its powerful CORSAIR iCUE software, allowing users to create custom fan curves and monitor power settings. This level of customisation can be particularly appealing to enthusiasts who want to optimise their systems for performance or acoustics. In contrast, the NZXT C850 SFX Gold does not mention any software customisation options, focusing instead on delivering a straightforward, reliable experience. For users looking to fine-tune their power supply performance, the HX1500i offers a significant advantage, while the C850 SFX Gold prioritises simplicity and ease of use.

User Experience and Community Trust

Both brands, Corsair and NZXT, have established reputations for reliability in the gaming and PC building communities. The CORSAIR HX1500i, with its high wattage and advanced features, is often favoured by gamers and PC builders who require robust power solutions for high-performance builds. The NZXT C850 SFX Gold appeals to a different segment, attracting users who need a reliable power source for compact systems while maintaining excellent efficiency. Ultimately, the choice may come down to community trust and personal preference, as both brands offer quality products backed by positive user reviews.

Which should you buy?

Deciding between the CORSAIR HX1500i and the NZXT C850 SFX Gold largely depends on your specific needs and budget. If you require a high-capacity power supply for a demanding system and are willing to invest more, the HX1500i is an excellent choice with its features and software customisation. However, if you are looking for a more affordable option that still delivers reliable performance in a compact form factor, the NZXT C850 SFX Gold is a fantastic alternative. Ultimately, your decision should align with your power requirements, space constraints, and budget considerations.
