Compact workstation GPU

The PNY RTX 4000 SFF Ada 20GB is a dual-slot half-height graphics card built on the Ada Lovelace architecture. It delivers 6144 CUDA cores, 48 RT cores and 192 Tensor cores for professional visualization and AI workloads. The board draws 70W and connects via a PCIe 4.0 x16 interface.

Suited for dense multi-display rigs

This card targets users who need four 5K outputs at 60Hz from a small chassis, such as medical imaging stations, broadcast walls or industrial control rooms. The 20GB GDDR6 ECC frame buffer protects data integrity in long-running compute tasks. Buyers needing full-height brackets, higher power limits or more than four display connectors should consider other models.

Build integration notes

A 70W TDP means a modest power supply and minimal auxiliary cabling are sufficient. The half-height profile fits 2U rack cases and compact workstations without blocking adjacent slots. Four Mini DisplayPort connectors drive quad 5K panels directly, freeing up CPU graphics outputs for other duties. The 160-bit memory bus and 280GB/s bandwidth keep data flowing for GPU-accelerated applications.

Questions about this item

What slot and power budget does the RTX 4000 SFF Ada 20GB need to run?

The card uses a PCIe 4.0 x16 slot and draws 70W, so the slot and board power must cover that.

Will the four Mini DP outputs on the RTX 4000 SFF Ada 20GB drive my existing 5K monitors at 60Hz?

Yes, each of the four Mini DP ports supports 5K at 60Hz for a four-display setup.

How can I confirm the RTX 4000 SFF Ada 20GB is operating correctly after installation?

Check that the driver shows 6,144 CUDA cores, 20GB GDDR6 ECC memory and a PCIe 4.0 x16 link running at full width.
