Corsair PSU vs Be Quiet Cable
Product category
You need a power supply unit to run your PC, not an accessory. Product A is the Corsair SF1000, a 1000-watt power supply. It converts wall power for your system. Product B is the Be Quiet! BC060. This is a CPU power cable. It connects a component to a power source. It is not a power supply itself. You cannot compare a PSU to a cable directly. They serve different roles in your build. One powers the system. The other delivers power to the CPU.
Wattage capacity
Your system needs sufficient power headroom. Product A provides 1000 Watts of continuous power. This high output supports demanding components and future upgrades. Product B does not list a wattage rating. It is a cable, so it carries power rather than generating it. The cable likely supports the wattage of the PSU it connects to, but it has no independent output capacity. For building a complete system, you need the unit with the wattage spec. The Corsair SF1000 offers clear power delivery capabilities that the cable lacks.
Modularity
Cable management affects airflow and aesthetics. Product A is fully modular. You only connect the cables you need. This reduces clutter inside your case. Product B is a single cable. It is not a modular unit itself. It is an accessory that might be part of a modular system. However, as a standalone item, it offers no modularity features. If you are looking for a power supply with flexible cable options, Product A is the only choice here. The cable cannot be managed independently of the PSU.
Efficiency rating
Efficiency impacts electricity bills and heat. Product A holds an 80 Plus efficiency rating. This means it converts AC power to DC power with minimal loss. Higher efficiency means less waste heat. Product B has no efficiency rating listed. Cables do not have efficiency ratings in the same way power supplies do. They have resistance, but that is not an 80 Plus standard. For energy-conscious building, the PSU rating matters most. The Corsair unit provides verified efficiency data. The cable provides no such data point for comparison.
Physical dimensions
Case compatibility depends on size. Product A measures 9.4 inches wide, 11.3 inches high, and 7.6 inches long. It weighs 2.31 pounds. This is a small form factor unit. Product B measures 9.06 inches long, 3.54 inches wide, and 1.18 inches high. It weighs 3 ounces. The cable is much smaller and lighter. However, the cable fits inside a case easily because it is flexible. The PSU requires specific clearance. Both fit in standard cases, but in different ways. The PSU is a component. The cable is an accessory.

Users needing a complete power supply unit
Product A is a 1000-watt power supply. It converts wall power for your system. Product B is a cable, not a PSU. You need the Corsair unit to run your computer. It features full modularity and an 80 Plus efficiency rating. The Be Quiet item is merely an accessory for your existing power supply.
Owners of existing Be Quiet power supplies
Product B is a Be Quiet! CPU power cable. It measures 0.45 meters in length. It is designed to connect to your existing power supply unit. Product A is a separate 1000-watt Corsair unit. If you already have a working PSU, you need this cable instead of a new power supply.
People building a new high-wattage PC
Product A provides 1000 watts of power. It is a fully modular unit with an 80 Plus rating. This allows you to manage cables easily. Product B is just a short cable. It cannot power your components on its own. You require the Corsair SF1000 to build a system with high power demands.
