Connector Goobay CAK S-15 2x 5.25 > 8 pin PCI-Expr

The Connector Goobay CAK S-15 2x 5.25 > 8 pin PCI-Expr is a multicolour internal cable that converts two 5.25" female power connectors into a single male 8‑pin PCI-Express power plug. Designed for use inside desktop PCs, the cable enables connection of power supply outputs to PCI Express graphics cards or other components that accept an 8‑pin PCIe power input. The product is offered under the PREMIUMCORD brand and is intended for upgrades, repairs or custom builds where a native 8‑pin PCIe power lead is not available.

Advantages

This adapter provides a compact and flexible solution for delivering power from two standard 5.25" peripheral connectors to an 8‑pin PCIe input. The multicolour cable construction assists with visual routing and identification inside the case. Its design focuses on ensuring a secure mating of connectors and compatibility with typical desktop power supply outputs and PCIe devices. The cable helps avoid the need to replace a power supply when an extra 8‑pin connector is required.

Suitable for

• Connecting a graphics card that requires an 8‑pin PCIe power plug when only 5.25" peripheral outputs are available
• Custom PC builds and system upgrades where additional PCIe power is needed
• Repairing or adapting older power supplies for modern PCIe components
• Temporary or test-bench setups where flexible cabling is helpful

Key specifications

• Cable type: adapter from two 5.25" female power connectors to one 8‑pin PCIe male connector
• Connector orientation: male 8‑pin PCI‑Express on one end, two female 5.25" on the other
• Use: internal PC power connection
• Colour: multicolour
• Brand: PREMIUMCORD

How to use

Switch off the PC and disconnect it from mains power before installation. Locate two free 5.25" peripheral power outputs from the power supply and plug them firmly into the female ends of the adapter. Route the cable inside the case to avoid obstructing fans or other components, then insert the male 8‑pin PCIe connector into the target device’s power socket until it seats securely. Reconnect mains power and power on the system to verify that the connected device receives power and operates normally.

Usage recommendations

Check the power requirements of the target PCIe device and the combined current rating of the two 5.25" outputs before using the adapter. Use this cable when the power supply can safely deliver sufficient current via the peripheral connectors; if in doubt, consider a power supply with native PCIe connectors. Avoid forcing connectors and keep cable routing clear of hot or moving parts.
