Single-slot workstation GPU

The NVIDIA RTX A4000 is a professional graphics card built on the Ampere architecture for workstation workloads. It provides 16GB of GDDR6 memory in a single-slot form factor measuring 4.4 inches tall by 9.5 inches long. The card connects via a PCI Express Gen 4 x16 interface and draws auxiliary power through one 6-pin PCIe connector. It is intended for professionals who need compute density in compact chassis.

Four DisplayPort 1.4 outputs

This card suits users driving up to four DisplayPort 1.4 displays from a single slot, such as multi-monitor CAD, simulation or visualisation stations. It is not aimed at gaming-focused builds or systems that require dual-slot cooling capacity. Buyers needing more video memory or higher thermal headroom for sustained double-precision compute should consider larger form-factor alternatives.

Fits slim workstations

The single-slot profile frees adjacent expansion slots for additional I/O cards, capture devices or storage controllers in dense workstations. A 6-pin PCIe power cable from the supply is required, and the 9.5-inch length must clear the chassis interior. The four DisplayPort 1.4 connectors support high-resolution panels without adapters, simplifying cable routing in tight enclosures.

Questions about this item

What power supply connector does the RTX A4000 need to run?

The card draws auxiliary power through a single 6-pin PCIe connector, so your power supply must provide that cable.

Will the RTX A4000 fit and run in a PCI Express Gen 3 motherboard slot?

Yes, the PCI Express Gen 4 x16 interface is backward compatible and will operate at Gen 3 speeds in an older slot.

How can I verify the four DisplayPort 1.4 outputs are active after installation?

Connect a monitor to each port; the OS should detect four separate displays and the NVIDIA control panel will list all four as enabled.
