Green PCB PCIe 4.0 x16 to dual x8 card with 20mm slot spacing and CPU4P power connector

Vszerda

Vszerda PCIe 4.0 x16 to x8x8 Split Card 20mm Spaced Slots CPU4P Power

SKU CH-WEBD-0082E

Splits one PCIe 4.0 x16 slot into two x8 slots spaced 20 mm apart with a CPU 4-pin power connector

  • Full PCIe 4.0 x16 bandwidth for two devices

  • 20 mm slot spacing fits dual-width cards
  • Gold-plated 5U contacts improve signal integrity
  • Gen 4 connector with dust plug protects pins

PCIe 4.0 x16 to Dual x8 Split Card

This Vszerda expansion card converts a single PCIe 4.0 x16 slot into two x8 lanes for multi-device configurations. It requires a motherboard BIOS that supports PCIe bifurcation to x8x8 mode. Gold fingers feature a 5U thickness for reliable contact. A CPU 4-pin power connector supplies auxiliary power to attached devices.

20mm Slot Spacing for Dual Expansion

The two x8 slots are spaced 20mm apart to accommodate dual-slot cards or riser cables without physical interference. Each slot uses a Gen 4 connector with a dust cover and retention latch. An onboard clock-splitting IC manages signal distribution across both lanes. A power-on LED provides immediate visual confirmation of activity.

Sustained Operation With Auxiliary Power

The dedicated CPU 4-pin port delivers supplemental current so both downstream devices maintain stable performance under continuous load. Gen 4.0 signalling remains compatible with Gen 3 hardware when bifurcation is enabled. The sinking gold process resists oxidation during extended use. This card suits builders adding a second accelerator or storage controller where slot clearance is limited.

Questions about this item

Will a single x16 slot deliver full PCIe 4.0 bandwidth to both x8 slots?

The card splits one x16 link into two x8 links, so each slot runs at PCIe 4.0 x8 speeds provided the motherboard BIOS enables x8/x8 bifurcation mode.

What does the CPU 4-pin power connector actually supply?

The auxiliary CPU 4-pin port feeds extra power to devices installed in the two slots, reducing load on the motherboard slot itself.

How much clearance do I need between the two expansion cards I plug in?

The slots are spaced 20 mm apart, so cards up to a dual-slot thickness will fit side by side without touching.
