Low-profile workstation card with 1 GB DDR3, 192 CUDA cores, DVI and DisplayPort 1.2 up to 3840×2160 at 60 Hz
The PNY Quadro K420 is a new professional graphics card built on the NVIDIA Quadro K4200 chipset with 192 CUDA cores and 1 GB of DDR3 memory on a 128-bit interface. It targets users who need certified drivers and stable output for CAD, DCC or multi-display office work rather than heavy compute or modern gaming. The low-profile form factor suits compact chassis where full-height cards cannot fit.
The card installs in any PCI Express 2.0 x16 slot and draws power solely from the bus, leaving external connectors free. DisplayPort 1.2 drives up to 3840 x 2160 at 60 Hz while the dual-link DVI supports 2048 x 1536 at 85 Hz, enabling two digital monitors without adapters. An ultra-quiet active fansink keeps thermals in check inside space-constrained enclosures.
Professionals maintaining older ISV-certified workflows on Windows or Linux will appreciate the DirectX 11 and OpenGL 4.4 support. Buyers who want more storage for textures, higher memory bandwidth, or modern APIs such as Vulkan should look at something else, as the 1 GB DDR3 frame buffer and Kepler-era feature set limit performance in current creative applications.

The 128-bit DDR3 memory bus and 1 GB frame buffer limit sustained throughput, so extended 3D workloads will hit bandwidth and capacity constraints before the 192 CUDA cores do.
The ultra-quiet active fansink is designed for low acoustic output, but continuous full-load operation will raise temperatures and fan speed above idle levels.
Yes, the board plugs directly into any PCI Express 2.0 x16 slot; no adapter or additional power connector is required.
