Splits one PCIe slot into four 16x connectors with USB 3.0 shielded cables and an IC heat radiator for GPU mining rigs
The Vszerda PCIe 1x to 16x riser splits a single PCI Express lane into four x16 slots for graphics cards used in bitcoin mining. It plugs directly into the motherboard without an extender cable and can be secured to the chassis. An integrated IC heat radiator helps manage component temperature during operation.
The board supports four high-speed PCIe 16x cards over shielded USB 3.0 cables that suit 1U, 2U and 3U chassis. Each slot accepts PCI-EX4, X8 or X16 devices, but total bandwidth remains limited to the upstream x1 link. Power for the floppy connector must be attached before use.
Flexible USB 3.0 shielded cables allow tidy routing inside compact server cases while reducing signal interference. The onboard IC heat radiator dissipates heat from the bridge chip without requiring active cooling. Correct insertion order — power first, then data — protects socket pins from damage.

No published specifications for this item yet.
Yes, the adapter is applicable to PCI-E x4, x8 and x16 slots, so it can be installed in any of those existing motherboard connectors.
The board includes an IC heat radiator; after powering on, check that the radiator warms slightly and that each of the four connected GPUs is detected by the mining software.
The package provides the 1x to 4-slot riser board with integrated USB 3.0 shielded cables; you will need to supply a floppy power cable and the four graphics cards yourself.
