NVVV MDR-20-12 AC to DC DIN-Rail Power Supply 12V 1.67 Amp 20W vs CORSAIR CX550 80 Plus Bronze Non Modular Low-Noise ATX 550 Watt Power Supply - N

Introduction to Power Supplies

When it comes to powering your electronic devices or computer systems, choosing the right power supply is crucial. In this comparison, we will explore two distinct products: the NVVV MDR-20-12 AC to DC DIN-Rail Power Supply and the CORSAIR CX550 80 Plus Bronze Non Modular Low-Noise ATX Power Supply. While both serve the fundamental role of providing power, they cater to different needs and applications.

Price Comparison

The NVVV MDR-20-12 is priced at C$21.41, making it an economical choice for those who require a specific low-power supply. In contrast, the CORSAIR CX550 comes with a significantly higher price tag of C$84.99. This substantial difference reflects the capabilities and features of each product. If budget constraints are a primary concern, the NVVV power supply is the more affordable option. However, those looking for robust performance in a more powerful unit may find the higher cost of the CORSAIR model justified.

Power Output and Efficiency

The NVVV MDR-20-12 provides a maximum output power of 20 watts with a primary output voltage of 12 volts and an output current of 1.67 amps. In comparison, the CORSAIR CX550 offers a much higher power supply capability of 550 watts. This dramatic difference in power output means the CORSAIR can manage much more demanding systems, making it ideal for gaming rigs or high-performance PCs. The efficiency of the CORSAIR is also noteworthy; it is 80 PLUS Bronze Certified, ensuring that it operates at an efficiency of up to 88%, which can lead to lower energy costs over time.

Design and Form Factor

The NVVV power supply is designed for DIN-rail mounting, making it suitable for industrial or commercial applications where space and installation type may differ from standard PC cases. On the other hand, the CORSAIR CX550 features a compact casing that fits comfortably into most modern PC cases, with a length of only 125mm. This design consideration makes it versatile for home and office setups. If you are building a custom PC, the more traditional form factor of the CORSAIR may be more appealing.

Noise Levels and Cooling

Noise levels can significantly impact user experience, especially in a home or office environment. The NVVV power supply does not specify any noise levels; it is generally assumed that its industrial application will not require low-noise features. In contrast, the CORSAIR CX550 is equipped with a 120mm thermally controlled low-noise cooling fan. This fan operates quietly during low loads and only increases speed under heavy stress, ensuring a quieter operation overall. For users sensitive to noise, the CORSAIR's design offers a considerable advantage.

Compatibility and Use Cases

The NVVV MDR-20-12 is tailored for specific applications that require a 12V output at lower wattages, making it ideal for powering smaller devices or industrial systems. Conversely, the CORSAIR CX550 is designed for general-purpose and gaming PCs, providing ample power for high-performance components. If your needs are more aligned with powering basic electronics or small systems, the NVVV is suitable; however, for gaming or intensive computing tasks, the CORSAIR is the clear winner in terms of versatility and power.

Warranty and Support

Warranty and support are essential factors when investing in a power supply. The NVVV product lacks specific warranty details, which may raise concerns regarding reliability and service. In contrast, the CORSAIR CX550 comes with a three-year warranty, backed by the support of CORSAIR’s global technical team. This assurance can provide peace of mind for users investing in a more expensive unit, as it indicates a commitment to customer satisfaction and product reliability.

Which should you buy?

In summary, choosing between the NVVV MDR-20-12 and the CORSAIR CX550 ultimately depends on your specific needs. If you require a cost-effective solution for low-power applications, the NVVV is an excellent choice at C$21.41. However, for those who need a reliable and efficient power supply for a gaming or high-performance PC, the CORSAIR CX550 at C$84.99 provides significant advantages in power output, efficiency, noise control, and customer support. Assess your requirements carefully to make the best decision for your power supply needs.
