Efficiency and Form Factor Comparison
Efficiency rating
The EVGA SuperNOVA NEX750B carries an 80PLUS Bronze certification, achieving up to 85% efficiency under typical loads. This standard is reliable for general desktop builds. The Cooler Master V750 SFX Gold offers a higher Gold efficiency rating. Gold units typically convert more electricity into usable power with less waste heat. Higher efficiency often means lower electricity bills over time and reduced strain on internal components. While both units provide 750W of output, the Cooler Master’s Gold rating gives it a clear advantage in energy conservation and thermal management for users who prioritize performance per watt.
Form factor
These power supplies target completely different chassis sizes. The EVGA unit follows the standard ATX12V specification, measuring 7.1 inches in length, 5.9 inches in width, and 3.4 inches in height. It fits standard mid-tower and full-tower cases. The Cooler Master V750 is an SFX unit, designed specifically for small form factor (SFF) builds. It measures only 3.94 inches in length, 4.92 inches in width, and 2.5 inches in height. If you are building a compact ITX system, the Cooler Master is the only viable option. For standard ATX cases, the EVGA fits without modification.
Modularity
The EVGA SuperNOVA NEX750B features a hybrid modular design. This allows you to connect only the cables you need, reducing clutter inside the case and improving airflow. Fully modular units let you remove all non-essential cables, while non-modular units have everything permanently attached. The hybrid approach offers a balance between cable management flexibility and simplicity. The data for the Cooler Master V750 SFX does not explicitly state its modularity type, though SFX units in this class often include customized short cables to reduce clutter. Without explicit confirmation, the EVGA’s hybrid modularity is a confirmed feature for cable management.
ATX version
The Cooler Master V750 supports the ATX 3.1 standard, which is the latest iteration for modern PC builds. This version ensures compatibility with the newest motherboards and power delivery requirements. The EVGA SuperNOVA NEX750B is certified for ATX12V/EPS12V standards but does not list ATX 3.1 or ATX 3.0 support in its specifications. For users building a system with the latest hardware, the Cooler Master’s adherence to the newer ATX 3.1 standard provides better future-proofing and compatibility with modern components compared to the older ATX12V certification of the EVGA unit.
PCIe connector
The Cooler Master V750 is ready for PCIe 5.1, featuring a 12VHPWR connector that can deliver up to 450W to high-end graphics cards. It includes 90-degree durable cables to improve electrical safety and reduce stress on the connector. This is essential for modern GPUs that require high power draws. The EVGA SuperNOVA NEX750B does not list PCIe 5.1 or 12VHPWR support in its specifications. It likely relies on standard PCIe connectors or older adapters. If you are using a modern, power-hungry GPU, the Cooler Master’s native PCIe 5.1 support is a significant advantage for direct, safe power delivery.
Build and protections
The EVGA SuperNOVA NEX750B lists extensive heavy-duty protections, including OVP, UVP, OCP, OPP, SCP, and OTP. It also uses Japanese brand capacitors for long-term reliability and a 2-ball bearing fan for quiet operation. These features ensure stability and safety for the entire system. The Cooler Master V750 mentions enhanced dissipation with an amorphous metal transformer and EMI inhibition, which aids in cooling and performance. However, it does not explicitly list the same suite of electrical protections in the provided data. The EVGA provides a more detailed list of safety features for component protection.
Which PSU fits your specific build needs
You are building a compact mini-ITX system
The Cooler Master V750 SFX Gold is designed specifically for small form factor cases. Its SFX dimensions fit into tight spaces where standard ATX units will not. You get Gold efficiency and PCIe 5.1 support in a package that prioritizes space saving without sacrificing power output for your components.
You prefer a standard ATX desktop tower
The EVGA SuperNOVA 750B is a standard ATX size unit that fits easily into most mid-tower and full-tower cases. It offers hybrid modularity to manage cable clutter and uses Japanese capacitors for reliability. This makes it a straightforward choice for traditional builds where size constraints are not an issue.
You need PCIe 5.1 readiness for new GPUs
The Cooler Master unit is explicitly PCIe 5.1 ready with a 90-degree 12VHPWR connector. This ensures compatibility with the latest graphics cards that draw up to 450W. The ATX 3.1 cables and enhanced dissipation design provide the necessary power delivery and thermal management for high-end modern hardware.
