Pci Express Cable(542)

PCIe cables on this page generally serve two roles:

• Power delivery: 6‑pin and 8‑pin (6+2) PCI Express power cables connect your power supply to a graphics card or other PCIe devices. You’ll also see splitters and adapters (for example, 8‑pin to dual 6+2, or SATA/Molex to 6‑pin) to match different setups.
• Slot extension: PCIe riser/extension cables (x16, x1, etc.) relocate a card away from the motherboard slot for airflow or unique builds.

Before you buy, check your device’s connector type, cable length and orientation (straight or 90‑degree), and make sure the cable fits your power supply and case layout.

They do different jobs in a PC build:

• VGA cable: A display cable that runs from your graphics card to a monitor. It carries video signals.
• PCIe cable: Cables used inside the case to power a graphics card (6‑pin/8‑pin) or extend a PCI Express slot with a riser.

They aren’t interchangeable. If you’re connecting a display, use the video port your monitor supports (VGA, HDMI, or DisplayPort). If you’re powering or relocating a card, look for PCIe power or riser cables sized for your hardware and case.

PCIe and Ethernet serve different purposes:

• PCIe: An internal expansion interface for devices like graphics cards and add‑in cards. Cables here include power leads and riser/extension ribbons used inside the case.
• Ethernet: A networking standard and cable used to connect your computer to a router or switch for internet and local network access.

They aren’t substitutes. A network card may plug into a PCIe slot, but the Ethernet cable still connects from that card’s port to your network hardware. Choose PCIe cables for internal power/extension needs and Ethernet cables for networking.

You’ll plug the PCIe power cable into two places:

1. Graphics card (or PCIe device): Align the 6‑pin or 8‑pin (6+2) connector with the matching socket(s) on the card. Don’t force a fit; the notches should line up.
2. Power supply: On a modular unit, use the PCIe‑labeled outputs; on non‑modular models, use the dedicated PCIe leads.

Power down and unplug the PC before working inside. Avoid using CPU/EPS cables in PCIe sockets—they look similar but are wired differently. If you’re unsure, checking the manuals for your card and power supply can help confirm the right connection.

Start by checking the power connectors on your graphics card:

• 6‑pin or 8‑pin (6+2): Match the plug style and the number of sockets on the card. Some cards require multiple connectors.
• PSU compatibility: For modular supplies, use PCIe‑labeled cables that fit your unit’s outputs. It’s generally best not to mix cables across different power supplies.
• Length and layout: Pick a length that reaches comfortably; right‑angle or 90‑degree options can help in tight spaces.
• Adapters/splitters: These can be helpful in certain builds, but it’s wise to consider your device’s power needs and the limits of the source connector before using them.

If you’re relocating the card, consider a PCIe riser/extension that matches your slot type and version.
