Connector GOOBAY CAK S-15 2x 5.25 to 8‑pin PCI-Express, multicolour

GOOBAY CAK S-15 is a power adapter cable that converts two 5.25" female peripheral (Molex) power plugs into a single 8‑pin PCI-Express (PCIe) male connector. The cable is intended to provide a stable power feed to PCIe devices such as graphics cards or other expansion cards when a dedicated 8‑pin output is not available from the power supply. The multicolour design makes cable routing and identification inside the PC case easier during installation and maintenance.

Advantages

The adapter allows the use of legacy peripheral power connectors to supply modern PCIe devices without modifying the power supply. It provides a compact single-cable solution that reduces the need to install a new PSU or additional adapters. The cable is straightforward to connect and helps maintain tidy cable management thanks to its clearly distinguishable multicolour wiring.

Suitable for

• Supplying 8‑pin PCIe power to a graphics card when only 5.25" peripheral outputs are available
• Upgrading or repairing older systems with limited native PCIe power connectors
• Temporary or test bench builds where a dedicated PCIe cable is not present

Key specifications

• Input: two 5.25" female peripheral (Molex) power connectors
• Output: one 8‑pin PCI-Express (PCIe) male power connector
• Compatibility: standard PC ATX power supplies with peripheral outputs and PCIe devices requiring an 8‑pin connector
• Colour: multicolour wiring for easy identification
• Connector orientation: standard straight-fit connectors for typical PC cases

How to use

Power down the system and unplug it from mains before connecting the adapter. Locate two available 5.25" peripheral power sockets from the power supply and connect the female ends of the adapter to them, ensuring firm seating. Route the cable to the graphics card or expansion card and plug the 8‑pin PCIe male connector into the device's power socket. After verifying secure connections and clear cable routing, restore power and power on the system. Monitor the system for stable operation and check device power indicators or system diagnostics as appropriate.

Usage recommendations

Use the adapter only as intended: to adapt existing peripheral power outputs to an 8‑pin PCIe input. Avoid using the cable as a permanent solution if the total power draw of the PCIe device approaches or exceeds the safe current capability of the source peripheral connectors; in such cases consider a PSU with native PCIe outputs or a dedicated high-current cable. Ensure good airflow and secure cable routing to prevent contact with moving parts or heat sources inside the case.
