CableMod 12VHPWR to 3×PCIe ModMesh cable 45cm red for PSU to GPU connections

CableMod 12VHPWR to 3×PCIe ModMesh cable 45cm red is a sleeved power cable that converts a single 12VHPWR plug to three PCIe 8‑pin connectors. With a 45 cm length and red ModMesh sleeving, this cable lets you connect multiple graphics cards or PCIe power adapters to a compatible modular power supply that provides a 12VHPWR output. The design balances compact routing with sufficient reach for common ATX and larger chassis layouts while preserving secure electrical contact for high-power GPU setups.

Advantages

The ModMesh sleeving provides durable abrasion resistance and a uniform appearance for custom builds, while the cable’s internal conductors are sized to support stable power delivery to multiple PCIe devices. The single 12VHPWR to triple 8‑pin configuration reduces the number of separate cables running from the PSU, improving airflow and cable management. Red sleeving offers a clear visual accent for themed systems without affecting compatibility with standard 12VHPWR and PCIe 8‑pin power interfaces.

Suitable for

• Powering multiple GPUs or GPU + PCIe-powered adapters from one 12VHPWR PSU output
• Custom gaming PCs and workstations requiring neat cable routing and aesthetics
• Systems where a single high-current PSU connector must be split into several standard 8‑pin PCIe plugs

Key specifications

• Cable type: 12VHPWR (single) to 3 × PCIe 8‑pin
• Length: 45 cm (end‑to‑end)
• Sleeving: ModMesh red sleeving
• Connector orientation: standard inline 12VHPWR plug to three separate right/straight 8‑pin PCIe plugs (manufacturer default orientation)
• Application: internal PSU to GPU/PCIe power distribution inside PC chassis

How to use

Ensure your power supply supports 12VHPWR output and that the combined current draw of connected PCIe devices does not exceed the PSU or connector rating. Connect the single 12VHPWR plug to the matching PSU output, then route the sleeved cable through the case to each graphics card or adapter and attach the individual PCIe 8‑pin plugs securely. Avoid sharp bends near connector ends and confirm all connections are fully seated before powering the system. Follow the GPU and PSU manufacturers’ guidelines for multi‑GPU power arrangements and required power capacity.

Recommendations

Use this cable only with compatible modular power supplies that provide a 12VHPWR output and ensure the PSU’s total available current matches the needs of all connected PCIe devices. For best cable management, plan routing to minimize crossing other components and keep the ModMesh sleeving clear of hot exhaust paths.
