Xpander Desktop Elite
Gen 3 User Guide
Xpander Desktop Elite (see the image at the
right) is a portable PCI Express (PCIe)
expansion enclosure that enables connection of
graphics processing units (GPUs) or other
controllers to a host computer. The host must
provide one PCIe x16 expansion slot available
for the host interface controller (HIC).
Install the x16 HIC and cable in a PCIe Gen 3
x16 slot to provide a theoretical 128Gbps
connection to Desktop Elite with four slots.
Desktop Elite provides four PCIe Gen 3 x16
slots on one mainboard for double-wide GPUs
that are NVIDIA® Compute Unified Device
Architecture (CUDA) or OpenCL-enabled.
Desktop Elite supports other PCIe adapters as
well. It supports applications that exploit
multiple GPUs, including rendering graphics or
high-performance computing (HPC).
Desktop Elite standard version features a 1,500Watt power supply, 4 x 8P + 8P auxiliary power
connectors and a fan that cools 4 x double-wide, actively-cooled GPUs. Optional versions
feature either a 1,600Watt power supply or a 1,200Watt power supply with 4 x 8P + 6P auxiliary
power connectors and a fan that cools 4 x double-wide, actively-cooled GPUs or other PCIe
cards. Adjustable fan settings (see page 8) allow quieter operation if fewer GPUs or single-wide
GPUs or other PCIe cards are installed.
