HOOCCC P2A PCIe 4.0 x16 to Dual x8 Split Card, Gen4 Bifurcation Riser with Clock Chip, 6-Layer PCB 5µm Gold Plated, SATA/4-Pin Power, Low-Profile for Dual GPUs NVMe SSDs

HOOCCC P2A PCIe 4.0 x16 to Dual x8 Split Card Product Description

Maximize your systems expansion potential with the HOOCCC P2A PCIe 4.0 x16 1-to-2 split card. Designed for enthusiasts, miners, workstations, and server builders, this bifurcation riser lets you turn a single PCIe x16 slot into two independent x8 channelseach running at full PCIe Gen4 x8 bandwidth. Whether youre running dual GPUs, NVMe RAID cards, capture cards, or other high-throughput PCIe devices, the P2A delivers the connectivity and signal stability you need.

True PCIe 4.0 x8/x8 Performance

The card accepts a PCIe x16 host connection and splits it into two x16 physical female sockets, each electrically wired as x8. Both ports operate simultaneously at PCIe 4.0 x8 speeds, ensuring minimal latency and maximum throughput for supported devices.

Built-In Clock Bifurcation IC

An integrated 1-to-2 clock bifurcation chip manages reference clock distribution between the two downstream ports, improving compatibility and stability. A dedicated power indicator LED provides instant visual confirmation that the card is receiving auxiliary power.

Server-Grade Build Quality

Constructed on a high-density, low-impedance 6-layer PCB, the P2A features gold-finger contacts with thickened 5-micron immersion gold plating for superior conductivity, oxidation resistance, and repeated insertion durability. New-generation LOTES Gen4 connectors keep high-speed signals clean and reliable.

Flexible Power & Compact Footprint

Choose from SATA-power or CPU 4-pin auxiliary power variants (the 4-pin version ships with a Large 4D-to-4-pin power cable included). The low-profile PCB design keeps the dual slots just 41 mm (2 cm) apart with 20 mm spacing, allowing comfortable installation of two full-size PCIe cards even in space-constrained builds.

Broad Compatibility

Tested and verified with multi-GPU setups (e.g., NVIDIA GeForce RTX 3060 Ti / 5060 Ti configurations) and other standard PCIe add-in cards. Note: Proper operation requires a CPU/chipset and motherboard BIOS that support PCIe bifurcation (x16 to x8/x8); some platforms may need manual BIOS adjustment.

Package Includes:

1 × HOOCCC P2A PCIe 4.0 x16 to Dual x8 Split Card (SATA or 4-Pin power version as selected); 4-Pin power version includes the 4D-to-4-Pin auxiliary cable.

Upgrade your rig with the HOOCCC P2A and unlock true dual-device PCIe Gen4 expansion without sacrificing bandwidth.
