Here are some details about a PCI 4 pin 1+16 raiser card:
- **Functionality:** The PCI 4 pin 1+16 raiser card is used to extend or raise a PCI Express (PCIe) slot for expansion cards, typically in situations where space is limited or for better cable management.
- **Connector:** It features a 4-pin Molex connector for power input and provides one PCIe x1 slot and one PCIe x16 slot for expansion cards.
- **Compatibility:** Compatible with various motherboards and chassis that support PCIe expansion slots.
- **Raising Capability:** The raiser card elevates the expansion cards, allowing for more flexibility in system design and better airflow within the chassis.
- **Installation:** Typically installed into an available PCIe slot on the motherboard and secured with screws or clips. The expansion cards are then connected to the raiser card.
- **Usage:** Commonly used in small form factor (SFF) or compact PC builds, such as mini-ITX or micro-ATX systems, where space is limited and traditional PCIe slots may not fit.
- **Benefits:** Allows for the installation of expansion cards in unconventional orientations or positions, optimizing the use of available space and improving system aesthetics.
- **Power:** Requires a 4-pin Molex power connector for operation, which provides power to the expansion cards connected to the raiser card.
Overall, the PCI 4 pin 1+16 raiser card offers a practical solution for expanding the capabilities of a system with limited space while maintaining compatibility with standard PCIe expansion cards.
