SMUGDESK 0.3M 16AWG PCIe 5.0 12VHPWR 16Pin to Dual 8Pin Power Splitter Cord for Gaming Chassis Modding

PCIe 5.0 12VHPWR Splitter Cable

This 0.3 metre 16AWG power splitter converts two standard PCIe 8Pin outputs into one 12+4 Pin 12VHPWR male connector. It is built for RTX 40 and RTX 50 series graphics cards that require the new PCIe 5.0 power interface. The heavy-gauge oxygen-free copper conductors reduce voltage drop and overheating risk under full load.

PSU Modular Port Check

Verify that your modular power supply provides at least two free PCIe 8Pin ports and that its cables are detachable at the PSU side. The splitter only works with modular units; non-modular PSUs cannot accept the required dual 8Pin inputs. Ensure the PSU’s total wattage meets the graphics card manufacturer’s specification.

Thermals Noise And Power Draw

The 16AWG copper wires and dense braided sleeve minimise heat buildup and voltage loss during sustained high-current operation. The short 0.98 foot length keeps resistance low and improves airflow inside the chassis. A locking 12VHPWR connector prevents accidental loosening that can cause connector melting. No active cooling or moving parts are present, so the cable adds no audible noise.
