PCIe 5.0 x16 to x8+x4+x4 splitter card

The HOOCCC P1L converts a single PCIe 5.0 x16 slot into three independent channels: a PCIe 5.0 x8 slot for a graphics card, an M.2 Key M slot running at PCIe 4.0 x4 for NVMe storage, and an additional PCIe 4.0 x4 interface for other expansion cards. It targets enthusiasts and professionals who need simultaneous GPU and high-speed storage expansion from one motherboard slot.

6-layer gold-plated PCB with dual brackets

A 6-layer circuit board uses immersion gold on the gold fingers and connectors to preserve signal integrity at high bandwidth. The card ships with both full-height and low-profile mounting brackets, allowing installation in standard ATX chassis or compact small-form-factor builds without modification.

Adds GPU and NVMe capacity to one x16 slot

This adapter replaces the need for a motherboard with multiple full-length PCIe 5.0 slots by splitting one x16 connection into graphics and storage pathways. The upgrade is worth it when your platform offers only a single x16 slot but you require both a discrete GPU and an additional NVMe drive or expansion card at the same time.

Questions about this item

Does the PCIe 5.0 x16 slot split into a 5.0 x8 link for the graphics card?

Yes, the single x16 slot is divided into one PCIe 5.0 x8 lane for a GPU, one PCIe 4.0 x4 M.2 NVMe slot, and one PCIe 4.0 x4 interface, all running simultaneously.

What bracket heights are included for the chassis?

Both a full-height bracket and a low-profile bracket are supplied, so the card fits standard ATX cases and slim small-form-factor builds.

Is any driver or BIOS setup required to activate the M.2 NVMe slot?

No extra driver is needed; the slot appears as a native PCIe 4.0 x4 link once the card is seated in a PCIe 5.0/4.0/3.0 x16 slot and the M.2 drive is secured with its screw.
