## Summary description

PREMIUMCORD KN-9 is a power adapter cable that converts a 5.25" Molex connector to a 6‑pin PCIe plug for graphics cards. It enables powering older PSUs without native PCIe rails, supporting standard 6‑pin PCIe power delivery. Suitable for installing or testing GPUs in desktop systems where only Molex outputs are available.

## Long description

PREMIUMCORD KN-9 is a compact power adapter cable that converts a standard 5.25" Molex connector into a 6‑pin PCIe plug to supply power to graphics cards. The cable allows systems with older power supplies that lack native PCIe power rails to connect GPUs requiring a 6‑pin PCIe connector. Designed for internal desktop use, this adapter provides a straightforward physical interface between Molex peripheral outputs and the PCIe power input on graphics cards.
Advantages
The adapter provides a simple and space-saving solution to power a GPU from existing Molex outputs without modifying the power supply. It supports standard 6‑pin PCIe power pinout so the graphics card receives the expected voltage lines. The cable’s compact form factor and fixed wiring reduce setup time when installing or testing graphics cards in systems where native PCIe connectors are absent.
Suitable for
Installing a graphics card in a desktop PC with an older power supply that only has Molex peripheral connectors
Testing or benching GPUs on systems or test rigs without dedicated PCIe power rails
Temporary or diagnostic connections when troubleshooting GPU power issues
Key specifications
Input connector: single 5.25" Molex peripheral connector
Output connector: standard 6‑pin PCIe power plug
Purpose: converts Molex power to 6‑pin PCIe for graphics cards
Cable length: compact internal cable suitable for short routing inside desktop cases
Usage environment: internal desktop PC use only
How to use
Power off the computer and unplug the power supply before installing the adapter. Locate a free 5.25" Molex peripheral connector from the power supply and firmly connect it to the adapter’s Molex end. Route the cable inside the case to the graphics card and insert the 6‑pin PCIe plug into the card’s power socket until it clicks. After ensuring all connections are secure and no cables obstruct fans or other components, reconnect mains power and power on the system. Verify that the graphics card receives power and the system posts before normal operation.
Usage recommendations
Use this adapter only as a temporary or compatibility solution with older power supplies. Ensure the PSU can supply adequate 12V current on the Molex rail for the GPU’s power draw; if the graphics card’s power requirement approaches or exceeds the PSU’s capacity, use a modern power supply with native PCIe connectors. Do not modify the cable or connectors; avoid using the adapter in wet or dusty environments and ensure proper cable routing to prevent strain on connectors.
