Wattage output

Edge: Apevia 300W TFX Power Supply

The Apevia TFX-AP300W delivers a maximum of 300W of power. It provides specific rails, including +12V at 20A and +5V at 12A. The Be Quiet! cable does not have a wattage rating. It is a passive component. It carries power from a supply to the CPU. It does not generate or limit wattage on its own. The Apevia is the only item here that provides electrical output. You need the Apevia to power your system components.

Fan cooling

Edge: Apevia 300W TFX Power Supply

The Apevia power supply includes a single 80mm fan for forced air ventilation. This helps manage heat during operation. The Be Quiet! cable has no moving parts. It does not have a fan. It relies on the power supply and case airflow for cooling. The Apevia requires power to run its fan. The cable requires no power for itself. The Apevia handles thermal management actively. The cable is passive. This is a key difference in how they operate.

Voltage regulation

Edge: Apevia 300W TFX Power Supply

The Apevia specifies a 5% tolerance for its 5V, 3.3V, and 12V outputs. This ensures stable voltage levels for your components. The Be Quiet! cable does not regulate voltage. It simply conducts electricity. It has no internal circuitry for adjustment. The Apevia manages power quality. The Be Quiet! cable transfers it. If you need stable voltage regulation, the Apevia provides that feature. The cable offers no regulation capabilities.

Physical dimensions

Edge: Tie

The Apevia power supply is larger, measuring 6.75 inches long, 3.23 inches wide, and 2.5 inches high. It is built to fit inside a case. The Be Quiet! cable is smaller in volume but longer in length. It measures 9.06 inches long. The cable is thin and flexible. The Apevia is a rigid box. You must choose based on your case size. The Apevia needs a TFX slot. The cable needs routing space. They serve different physical roles in your build.
