SIWOAXA 4 Pin P4 CPU Extension

The SIWOAXA 4-pin P4 CPU power extension cable adds 8 inches of reach between a 12 V power supply and the motherboard CPU connector. It suits desktop builders whose stock cable falls short in larger or tightly routed cases. The male-to-female design plugs in without tools and a safety lock helps prevent accidental disconnection.

Thermals noise and power draw

Copper core conductors carry the 12 V supply with minimal resistance so the extension does not add measurable heat or voltage drop during normal operation. The solid connectors maintain a tight fit that avoids intermittent contact and the associated power interruptions. No active cooling or fan is involved so the assembly is completely silent.

Sustained load behaviour

Under continuous CPU load the copper conductors and secure locking plugs keep power delivery stable without degradation over time. The 8-inch length is suited to compact chassis where cable routing space is limited and helps keep internal wiring tidy. Builders needing longer runs or multiple CPU power connectors will need a different solution.

Questions about this item

How do I attach the 4-pin P4 CPU power extension cable and which step do people often miss?

Plug the male end into the PSU 12V connector and the female end onto the motherboard 4-pin CPU header until the safety lock clicks; the step most people miss is not pushing far enough to engage that lock.

What upkeep or replacement will the 8-inch copper-core extension need over time?

No scheduled maintenance is required; inspect the connectors if you rebuild the system and replace the cable only if the safety lock breaks or the pins show corrosion.

What limit appears first when the 4-pin P4 extension runs continuously under load?

The 8-inch length and copper conductors are rated for the CPU 12V rail, so the first practical limit is the PSU or motherboard header rating, not the cable itself.
