Description

This assembly is a high‑current 12VHPWR (12+4 pin) power cable designed to link a 3.0/PCIe 5.0 power supply directly to a graphics card equipped with a 12VHPWR receptacle. Both ends use locking 16‑pin plugs with molded strain reliefs to ensure full engagement at the PSU and GPU. The 30 cm length helps move the bend point away from the connector housing to reduce heat build‑up from tight bends, supporting reliable delivery of 12 V power and sense signals for modern high‑draw accelerators such as NVIDIA RTX 40‑series.

Farsince builds the harness with high‑strand copper conductors and low‑resistance crimp terminations to support up to 600 W per the ATX 3.0 specification when used with compliant PSUs and GPU connectors. Individual conductor grouping maintains flexibility while a flat profile eases routing behind trays or past radiators. Installation is straightforward: insert each plug fully until the latch engages and avoid sharp bends within a few centimeters of the housing. OEM customization is available for length, sleeving, angled overmolds and project‑specific labeling.
