Computer Cable Adapters

Finding the exact computer cable adapters and power cords is crucial for system stability and hardware safety. Whether you need a standard IEC C13 power cord for a desktop PC, a Molex to SATA splitter for internal storage expansion, or an industrial RS232 serial adapter, we have the precise connectivity solution. Backed by 20 years of IT retail experience, Sun Cheong Computer (新昌電腦) provides on-site component matching and ready-stock availability in Sham Shui Po to ensure your devices connect flawlessly without signal loss or power failure.

PC Connectivity & Industrial Cable Specifications

Selecting the correct cable involves matching connector types, voltage ratings, and data transfer protocols. Here is a technical breakdown of our core computer cable inventory:

Cable Category Key Technical Specifications Best Use Case
IEC Power Cords C13 (Kettle), C5 (Mickey Mouse), C7 (Figure-8) Powering desktop PC power supplies (PSUs), laptop chargers, and monitors.
Internal PC Cables SATA III (6Gbps), 4-Pin Molex to SATA, 3-Pin Fan Extensions Expanding motherboard storage (SSD/HDD) and optimizing PC case cooling.
Industrial Serial Adapters USB to RS232 (DB9), FTDI / CH340 Chipsets Connecting modern laptops to legacy CNC machines, PLCs, and network switches.
Display & Video Adapters DVI-D to HDMI, Micro HDMI, DisplayPort Converters Setting up dual-monitor workstations and connecting to legacy projectors.

Important Note (Hardware Limitation & Fire Hazard): When expanding internal PC storage, be extremely cautious with "Molex to SATA" power adapters. Cheaply manufactured "molded" adapters are notorious for causing electrical shorts and fires because the injection molding process can shift the internal wires too close together. We strongly recommend using "crimped" SATA adapters or relying on the native SATA power cables from your ATX power supply to prevent catastrophic hardware damage.

Frequently Asked Questions (FAQ)

Q: Are all IEC C13 computer power cords the same?
A: No. The safety and capacity of a power cord depend entirely on its internal wire gauge (measured in AWG or mm²). A standard 18AWG cord is sufficient for a regular office PC or monitor. However, if you are powering a high-end gaming rig with a 1000W+ PSU or an enterprise server, you must use a thicker 14AWG or 1.0mm² heavy-duty cord to prevent the cable from overheating and melting.

Q: I bought a USB to RS232 cable online, but Windows 11 says "Driver Error". Why?
A: This occurs because many cheap serial cables use counterfeit Prolific (PL2303) chips, which modern Windows updates actively detect and block. For professional and industrial environments, you must use an adapter with a genuine FTDI chipset or a verified CH340 chip. We stock Z-TEK industrial-grade serial adapters that guarantee plug-and-play compatibility across Windows, Mac, and Linux systems.
