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. You can expect the same performance from these cards as if they were located on the workstation chassis and it will operate just as it would if installed on the motherboard.
