8-Pin to Dual 4-Pin Molex GPU Power Cable – 25cm | OULLX

8-Pin PCIe to Dual 4-Pin Molex Graphics Card Power Cable

Keep your graphics card running at peak performance with the OULLX 8-Pin Male to Dual 4-Pin Molex Male Power Cable. This 25cm adapter cable bridges your PC power supply's existing Molex connectors to your GPU's 8-pin PCIe power port, delivering stable, uninterrupted power for smoother, more reliable graphics performance.

Made in Mainland China.

Key Features

• Stable GPU Power Delivery: Converts two standard 4-pin Molex connectors into a single 8-pin PCI Express output, ensuring your graphics card receives consistent, adequate power for stable operation.
• High-Quality Thick-Core Wiring: Built with premium, heavy-gauge wire for reliable conductivity and durability — minimizing resistance and heat build-up during operation.
• Smart Wiring Design: Uses IDE 4-pin interface adapters — one port with 3 cores (5 wires output) and one port with 2 cores (3 wires output) — combining for exactly 8 wires to correctly power an 8-pin GPU connector.
• Compact 25cm Length: Short enough to keep your cable management tidy inside any mid-tower or full-tower case, with just enough reach for a clean build.
• No Assembly Required: Plug-and-play design — no tools or modifications needed. Simply connect the two Molex ends to your power supply and the 8-pin end to your graphics card.
• Safe Series Connection: Designed for auxiliary series connection. Ensure your power supply has at least 2 active Molex lines for correct operation.

Frequently Asked Questions

Q: What does the 8-pin to dual 4-pin Molex power cable do?

A: This cable allows you to connect two standard 4-pin Molex connectors from your PC power supply into a single 8-pin PCI Express power port on your graphics card. It ensures your GPU receives adequate power for stable, high-performance operation — especially useful when your PSU lacks a dedicated 8-pin PCIe connector.

Q: Is this cable compatible with all 8-pin PCIe graphics cards?

A: This cable is designed for graphics cards that use a standard 8-pin PCI Express power connector. Always verify your GPU's power requirements and ensure your power supply can deliver sufficient wattage through at least 2 active Molex lines before use.

Q: How long is this GPU power adapter cable?

A: The cable measures 25cm (approximately 9.8 inches) in length, making it ideal for neat cable management inside most PC cases while providing enough reach to connect your power supply to the graphics card comfortably.

Q: Do I need any tools to install this cable?

A: No tools are required. The cable is a plug-and-play solution — simply power down your PC, unplug it from the wall, connect the two 4-pin Molex ends to your PSU and the 8-pin end to your GPU, then power your system back on.
