Frequently Asked Questions about our products before you buy
Unfortunately, the Thunderbolt card we make only works as a target device. While it has a PCIe card edge connection it is a slightly custom pin-out and the device on the card is set in downstream mode. The Thunderbolt spec makes it difficult and costly to make a Thunderbolt certified host card. Many parameters of Thunderbolt are tied directly to motherboard resources that are not part of the PCIe slot.
For PCIe Gen 1 and Gen 2 products, cable lengths run from .5m to 7m. Gen 3 products operate best on cable lengths up to 1m. The CUBE-PCIe x4 is a Gen 2 product that ships with a 1m PCIe x4 cable. You can order an additional PCIe x4 .5m, 1m, 2m, 3m, 5m, or 7m cable cable separately if you need a longer cable.
The Cube allows any PCIe peripheral to plug into a laptop via PCIe Express Card slots or Thunderbolt slots including GPUs for video or GP GPU rendering. While there are no hardware restrictions on this connection, the laptop BIOS may limit the types of hardware supported over the PCIe or Thunderbolt link. In addition, some peripheral drivers may not support the operating system of some laptops or embedded products with ExpressCard or Thunderbolt ports.
Expansion products including The CUBE offer added functionality and performance, and they are also reliable and cost-effective. The CUBE provides a solution to some common I/O obstacles like your PC not having enough slots, power, or cooling to support some large cards. The CUBE really provides the most valuable solution with the growing market for GPUs. GPUs often require greater bandwidth, power, and cooling that The CUBE can provide with PCIe expansion.
The CUBE enclosures support up to PCIe x16 add-in cards including the latest Gen3 GPUs. However the speed at which any card operates is dependent on the speed of the bus connecting them to the host computer. In the case of Thunderbolt the data connection operates at 10Gb/s.
Yes, each One Stop Systems cable adapter just needs its own PCIe x16 host interface, so if the host system has available slots it’s ready to go.
