CableMod RT-Series PRO ModMesh 12VHPWR to 3x PCI-e cable for ASUS/Seasonic, 60 cm, black/light green

The CableMod RT-Series PRO ModMesh 12VHPWR to 3x PCI-e cable for ASUS/Seasonic is a sleeved adapter designed to convert a single 12VHPWR (16-pin) power supply output into three standard PCI‑Express power connectors. At 60 cm length, the cable provides reach for varied internal layouts while the ModMesh sleeving in black with light green accents offers a balance of flexibility and cable protection for tidy routing in ATX desktop cases and custom builds.

Advantages

This adapter enables distribution of a single high‑current 12VHPWR output to multiple PCI‑e devices without requiring additional PSU connectors. The ModMesh sleeving improves airflow clearance and reduces cable snagging during installation. A 60 cm overall length allows routing behind motherboards or along case edges, and the sleeved finish helps maintain a consistent aesthetic in black/light green systems compatible with ASUS and Seasonic power designs.

Suitable for

• Systems using a single 12VHPWR PSU output that need to power multiple PCI‑Express graphics cards or devices
• Custom PC builds where cable management and visual coordination are important
• Upgrading or adapting power distribution for high‑power GPUs requiring 12VHPWR connectors

Key specifications

• Cable type: Adapter, 12VHPWR (16‑pin) to 3 × PCI‑Express power connectors
• Length: 60 cm (overall)
• Sleeving: ModMesh fabric, black with light green accents
• Compatibility: Designed for use with ASUS and Seasonic compatible graphics cards and PSUs supporting 12VHPWR
• Connector orientation: Standard male 12VHPWR input with three female PCI‑e outputs

How to use

Power off the system and disconnect the PSU from mains before installing the adapter. Plug the 12VHPWR end into the corresponding PSU output, ensuring a secure, fully seated connection. Route the sleeved cable along the case interior to minimize obstruction to fans and airflow, and connect the three PCI‑e outputs to the graphics card(s) or PCI‑e devices following the device manufacturer’s connector arrangement. Verify all connections are firm before powering the system on.

Recommendations

Use this adapter only with power supplies and devices that support the 12VHPWR standard and observe the total power draw limits of your PSU. Avoid forcing connectors and ensure cable routing does not pinch or excessively bend the sleeving. For multi‑GPU setups or high‑power cards, confirm thermal and power requirements with the GPU manufacturer and monitor voltages and temperatures after first use.
