Comparing EVGA NEX750B Alternatives
EVGA 500 BQ 500W Semi-Modular Power Supply
The EVGA 500 BQ offers 500W of power, which is significantly less than the NEX750B’s 750W. It uses semi-modular cabling rather than the hybrid design found in the NEX750B. This unit is smaller, measuring 5.51 inches in length compared to the 7.1-inch NEX750B. It features a 120mm fluid dynamic bearing fan, whereas the NEX750B uses a 2-ball bearing fan. You should choose this option if your build has lower power requirements and needs a more compact chassis. It retains the 80 Plus Bronze efficiency rating but sacrifices wattage and some modularity flexibility for a smaller footprint.
Corsair CX-M Modular Power Supply
The Corsair CX-M Modular PSU provides modular cabling instead of the hybrid modularity of the NEX750B. It shares the same 80 Plus Bronze efficiency rating. The primary difference lies in the cabling management; the Corsair unit requires you to connect all cables manually if you do not need them, unlike the semi-modular NEX750B which has essential cables permanently attached. This unit is presented as a renewed package, suggesting it is a refreshed version of standard desktop power supplies. It is a suitable alternative if you prefer full modular flexibility and do not need the specific hybrid design or Japanese capacitors highlighted in the NEX750B.
FSP 300W Flex ATX Power Supply
The FSP 300W Flex ATX PSU is designed for Mini ITX systems, making it much smaller than the standard ATX NEX750B. It measures 3.2 inches wide and 1.6 inches high, fitting into tight spaces where the NEX750B cannot. While it has lower wattage, it offers 80 Plus Gold efficiency, which is superior to the NEX750B’s Bronze rating. This unit is ideal for low-draw builds that require high electrical efficiency in a compact form factor. You would pick this over the NEX750B if your case size is restricted and your components do not require 750W of power delivery.
The EVGA 650 BQ provides 650W of power, which is 100W less than the NEX750B. It uses semi-modular cabling rather than the hybrid design of the NEX750B. This unit features a larger 140mm fan compared to the NEX750B’s fan, potentially affecting noise profiles. It includes a five-year warranty, which is a specific coverage term not explicitly detailed in the NEX750B’s provided specifications. It shares the 80 Plus Bronze efficiency rating. You should consider this alternative if you need slightly less power but want a different fan size or specific warranty terms, while accepting the reduction in maximum wattage output.
The Thermaltake Toughpower Grand RGB 850W PSU offers 850W of power, which is 100W more than the NEX750B. It is a semi-passive thermal control unit with digital PFC regulation. The enclosure depth is 6.3 inches, which is shorter than the 7.1-inch length of the NEX750B. It is designed for full-size ATX builds that require higher wattage. This unit is a better choice if your system demands more power than 750W and you prefer a shorter chassis depth. It lacks the explicit efficiency rating details in the provided data but offers higher capacity and different thermal management features.
SilverStone 700W SFX 80 Plus Gold Power Supply
The SilverStone 700W SFX PSU is built for small cases, using the SFX form factor instead of the standard ATX size of the NEX750B. It offers 80 Plus Gold efficiency, which is higher than the NEX750B’s Bronze rating. This unit is fully modular, providing more cabling flexibility than the hybrid design of the NEX750B. It measures 3.94 inches wide and 2.5 inches high, fitting into compact builds where the larger NEX750B will not fit. You should choose this option if you need high efficiency and full modularity in a small form factor, accepting the SFX size constraint.
