EVGA PSU vs Be Quiet Cable
product type
You are comparing two very different items. Product A is the EVGA SuperNOVA NEX750B, a complete 750W power supply unit. It delivers primary power to your entire system. Product B is a Be Quiet! CPU power cable, model BC060. It is a single component, measuring 0.45 meters long. It does not generate power. It simply connects a CPU connector to your existing supply. One is a core component. The other is an accessory. This is a fundamental difference in what you are buying.
efficiency rating
Efficiency matters for your electricity bill and heat output. The EVGA SuperNOVA NEX750B carries an 80PLUS Bronze certification. This means it achieves up to 85% efficiency under typical loads. You get better energy conversion. The Be Quiet! cable has no efficiency rating. Cables do not have efficiency ratings because they do not convert AC to DC. They just conduct electricity. For efficiency, the EVGA unit is the only relevant choice here. The cable cannot compete on this metric.
modularity
Modularity helps with cable management and airflow. The EVGA SuperNOVA NEX750B features a hybrid modular design. You can connect only the cables you need. This reduces clutter inside your case. The Be Quiet! cable is a single, fixed-length wire. It is not modular. It is a dedicated cable for one specific connection. You cannot detach it from a modular system because it is not part of one. The EVGA design offers flexibility. The cable offers fixed utility.
protection features
Protection features keep your components safe. The EVGA SuperNOVA NEX750B includes heavy-duty protections. These include Over Voltage Protection, Under Voltage Protection, Over Current Protection, Over Power Protection, Short Circuit Protection, and Over Temperature Protection. The Be Quiet! cable has no listed protection features. Cables do not have active protection circuits. They are passive conductors. Only the EVGA unit provides these safeguards for your hardware. This is a critical advantage for system stability.
physical size
Size affects fit in your case. The EVGA SuperNOVA NEX750B measures 7.1 inches in length, 5.9 inches in width, and 3.4 inches in height. It weighs 7 pounds. The Be Quiet! cable is much smaller. It is 9.06 inches long, 3.54 inches wide, and 1.18 inches high. It weighs only 3 ounces. The EVGA unit is a large box. The cable is a thin wire. You need a case with enough space for the EVGA unit. The cable fits anywhere.
Which PSU fits your build needs
Users needing a complete 750W power source
You need a full power supply unit. The EVGA SuperNOVA NEX750B delivers 750W of power. It holds 80PLUS Bronze certification for efficiency. This hybrid modular design helps manage cable clutter. The included protections safeguard your components against voltage or current issues. This is the only complete unit in this comparison.
Owners replacing a single CPU cable
You are looking for a replacement cable, not a power supply. The Be Quiet! BC060 is a 0.45-meter CPU power cable. It fits standard ATX cases. The black color matches most builds. This item does not provide power to your system. It only extends the connection from the PSU to your processor socket.
Builders prioritizing component protection and efficiency
You want reliable power delivery and safety features. The EVGA unit includes over-voltage, under-voltage, and over-current protection. It uses Japanese capacitors for longevity. The 85% efficiency rating reduces wasted energy as heat. The quiet 2-ball bearing fan maintains stable temperatures. These specs support a stable and efficient system build.
