Green circuit board with two white PCIe slots spaced 20mm apart and a 4-pin power connector

Vszerda

Vszerda PCI-E 4.0 x16 to 2 x8 Bifurcation Card 20mm Spaced Slots CPU4P Power

SKU CH-BGDX-ZT38E

Adds two PCIe 4.0 x8 slots from a single x16 slot with 20 mm spacing and CPU 4-pin auxiliary power

  • Full PCIe 4.0 x16 bandwidth splits to dual x8 slots
  • Gold fingers thickened to 5U for reliable contact
  • Gen4 connectors include dust plugs and locking snaps
  • 20 mm slot spacing fits wider expansion cards
  • CPU 4-pin auxiliary power port with included cable

PCIe 4.0 x16 bifurcation card

This PCIe 4.0 x16 to dual x8 bifurcation card splits a single full-bandwidth slot into two x8 lanes. It targets builders whose motherboard BIOS supports x8/x8 mode switching and who need two expansion cards spaced closely together. The gold fingers use a 5U thickness for reliable contact.

Thermals noise and power

The card draws auxiliary power through a CPU 4-pin connector and includes a 4-pin cable for the connection. A power-on LED indicator shows when the auxiliary supply is active. No active cooling is present so the card adds no fan noise to the system.

Sustained load behaviour

A clock-splitting IC manages signal integrity across both x8 links during continuous data transfers. The Gen4 connectors include dust plugs and snap retention to maintain contact under vibration. The 20 mm slot spacing is fixed and limits the physical width of cards that can be installed side by side.

Questions about this item

How do I install the Vszerda PCIe 4.0 bifurcation card and what BIOS setting is required?

Insert the card into a PCIe x16 slot, connect the CPU 4-pin power cable, then set the motherboard BIOS to split the slot into x8/x8 mode.

What maintenance or replacement will the Vszerda bifurcation card need later?

The gold fingers use a 5U gold-plated finish for durability, and the Gen4 connectors include dust plugs to protect unused ports.

What limit appears first on the Vszerda card under sustained use?

The card requires the motherboard to support x8/x8 bifurcation; without that BIOS option the second slot will not function.
