## Summary description

Thermalright TG-WV-P38H1R is a power cable adapter that converts a single 12VHPWR connector to three 8‑pin PCIe connectors with reverse wiring. Intended for GPU power delivery, it enables connection of multiple 8‑pin PCIe cables to GPUs requiring a 12VHPWR interface. Useful when upgrading graphics cards while reusing existing PSU cables to maintain compatibility and supply required power.

## Long description

Thermalright TG-WV-P38H1R is a power cable adapter that converts one 12VHPWR connector into three 8‑pin PCIe connectors using reverse wiring. Designed for GPU power delivery, the adapter allows systems with existing 8‑pin PCIe power cables to connect to graphics cards that use the newer single 12VHPWR plug. The compact cable assembly preserves pin mapping required for reverse-wired configurations and supports practical reuse of power supply cabling when upgrading or replacing a graphics card.
Advantages
The adapter provides a straightforward way to bridge legacy 8‑pin PCIe cabling with modern 12VHPWR GPU inputs without modifying the power supply. Reverse wiring ensures compatible pin assignment for specific GPU designs and helps avoid custom splicing or purchasing new modular cables. The compact design reduces cable clutter inside the chassis while enabling distribution of current across three 8‑pin connectors for stable GPU power delivery.
Suitable for
Systems where an existing PSU has multiple 8‑pin PCIe cables but the GPU requires a 12VHPWR connector
Upgrades to a new graphics card while reusing compatible PSU cabling
Building or testing rigs that need flexible GPU power routing without replacing the PSU
Key specifications
Input: 1 × 12VHPWR (female) to 3 × 8‑pin PCIe (male) via reverse wiring
Purpose: GPU power adapter for 12VHPWR to multiple 8‑pin PCIe connections
Cable arrangement: compact multi-branch assembly intended for internal PC use
Compatibility: designed for systems using standard 8‑pin PCIe power cables and GPUs with 12VHPWR sockets
Connector orientation: reverse-wired pin mapping to match specified GPU power pinout
How to use
Power off the system and disconnect it from mains power prior to installation. Insert the adapter’s 12VHPWR plug into the GPU’s 12VHPWR socket, then connect up to three 8‑pin PCIe power cables from the PSU to the adapter’s PCIe outputs. Ensure each 8‑pin cable is fully seated and that cable routing does not place strain on connectors. After all connections are secure, reconnect mains power and power on the system. Verify stable operation and monitor GPU power draw during initial use.
Usage recommendations
Use the adapter only with power supplies and cables that meet the required current and safety specifications for your GPU. Distribute the GPU’s power across all three 8‑pin cables to reduce load on individual wires. Do not use the adapter if any connector or cable shows damage, and consult the GPU and PSU documentation to confirm compatibility with reverse-wired adapters.
