ESGAMING SFX 500W / Mini ITX/Micro ATX vs CORSAIR CX750M

Price Comparison

The ESGAMING SFX 500W is significantly more affordable than the CORSAIR CX750M, priced at C$54.99 compared to C$124.99. This represents a price difference of C$70, making the ESGAMING option attractive for budget-conscious consumers. While the lower price of the ESGAMING power supply may entice those looking to save money, it is essential to consider the additional features and power capacity offered by the more expensive CORSAIR model.

Power Output

When comparing power output, the CORSAIR CX750M offers a substantial advantage with its 750W capacity, compared to the 500W provided by the ESGAMING SFX. This higher wattage allows the CORSAIR unit to support more demanding components, especially high-performance graphics cards. The CX750M can effectively deliver up to 600W of GPU power through a single cable, which is more than adequate for the latest Nvidia RTX 50-series and older 40-series GPUs. This makes the CORSAIR a better choice for users planning to build a powerful gaming rig.

Efficiency and Design

The ESGAMING SFX 500W features an Active PFC design, which contributes to improved efficiency and reduced energy waste. This can be particularly beneficial for users in areas with unstable power grids, as it handles voltage fluctuations better than traditional power supplies. In contrast, the CORSAIR CX750M adheres to the latest ATX 3.1 and PCIe 5.1 standards for power delivery, ensuring reliable performance over its lifespan. Both units focus on efficiency, but the CX750M’s adherence to contemporary standards may offer a slight edge in long-term reliability.

Cooling Solutions

Cooling solutions vary significantly between the two power supplies. The ESGAMING SFX is equipped with an 80mm silent fan that operates with auto-thermal control, ensuring quiet operation. Meanwhile, the CORSAIR CX750M boasts a larger 120mm low-noise fan, designed to run cool and quietly under low to medium loads. This larger fan could provide more effective cooling, particularly during heavy usage, potentially leading to improved longevity for the components inside the case.

Modular Design

The CORSAIR CX750M features a semi-modular design, which allows users to attach only the cables they need, reducing cable clutter and improving airflow within the case. This is particularly advantageous for those who favour a clean build aesthetic. In contrast, the ESGAMING SFX does not mention a modular design, implying that all cables are fixed. While this could simplify installation for some users, it may lead to a more cluttered interior for those who do not require all the provided connections.

Connector Variety

In terms of connector variety, the ESGAMING SFX 500W provides a wide range with multiple connections, including 1 x 24-pin Main Power, 2 x PCI 6+2pin for GPUs, and 4 x SATA connections. This variety ensures compatibility with numerous components. On the other hand, the CORSAIR CX750M is explicitly designed to support the latest high-performance GPUs without the need for adapters, thanks to its native 12V-2x6 cable. This makes it particularly appealing for gamers looking to future-proof their builds with new hardware.

Durability and Protection Features

Both power supplies come with essential protection features, but the ESGAMING SFX 500W boasts a comprehensive array of protections including Short-Circuit, Over-Current, Over-Voltage, Over-Power, Under-Voltage, and Over-Temperature protections. These features can safeguard connected components from damage. The CORSAIR CX750M, while not detailing as many protective features, focuses on delivering stable power and reliability over time, thanks to its adherence to modern power delivery standards.

Which should you buy?

Choosing between the ESGAMING SFX 500W and the CORSAIR CX750M largely depends on your specific needs and budget. If you are looking for an affordable option that provides essential features for a lower-powered system, the ESGAMING SFX is a solid choice at C$54.99. However, if you plan to build a high-performance gaming rig that demands more power and features, the CORSAIR CX750M is worth the investment at C$124.99, offering superior wattage, modular design, and enhanced cooling capabilities. Ultimately, your decision should hinge on the power requirements of your system and how much you are willing to invest in your build.
