Revitol PCI-E 1 to 4 USB 3.0 Expansion Card with 4× PCIe 1x to 16x Riser Cables 60 cm

PCI-E 1 to 4 USB 3.0 Expansion Card

This PCI-E 1 to 4 USB 3.0 expansion card adds four riser slots to a single PCIe x1 lane, targeting mining rigs or multi-GPU workstations that need more graphics-card connections than the motherboard provides. It includes four 60 cm USB 3.0 cables and matching 1x-to-16x riser boards for flexible placement.

Three solid capacitors and MOLEX 4-pin power

Each riser board uses three solid capacitors to smooth power delivery to the attached graphics card, while a large 4-pin MOLEX connector draws current directly from the PSU instead of the motherboard slot. The plug-in design lets the main board seat directly in the x1 slot and be screwed to the chassis for a secure fit.

Expands one x1 slot into four x16 mechanical slots

The kit replaces the need for multiple motherboards or specialised mining boards when the build only has a single free PCIe lane. The jump is worth it when the platform has spare PSU MOLEX leads and physical space for four cards, but it cannot increase total PCIe bandwidth beyond the single x1 link.
