Professional workstation GPU with 3 GB GDDR5

The PNY Quadro K4000 delivers 768 CUDA cores and a 192-bit memory interface for certified professional applications. It targets engineers, designers and scientists who need reliable viewport performance in CAD, DCC and visualisation workflows. The single-slot form factor suits dense workstation chassis where expansion space is limited.

Thermals and power in daily use

Maximum power draw is rated at 80 W and the card draws auxiliary power through a supplied 6-pin adapter cable. A single-slot cooler exhausts heat toward the rear bracket, keeping internal case temperatures manageable in typical workstation airflow. Noise remains low during standard modelling and rendering tasks.

Build integration and display connectivity

The board measures 240 mm long by 110 mm high and installs in a PCI Express 2.0 x16 slot. Two DisplayPort 1.2 outputs and one dual-link DVI-I port support up to three monitors with the included DP-to-DVI and DVI-to-VGA adapters. Buyers who need more than 3 GB of frame buffer or four native display outputs should consider other solutions.

Questions about this item

How do I install the VCQK4000-PB and what is the step people get wrong?

Insert the card into a PCI Express 2.0 x16 slot, connect the included 6-pin power adapter, and secure the 240 mm long bracket; the missed step is forgetting the auxiliary power cable.

What maintenance or replacement will the Quadro K4000 need later?

The 80 W design relies on a single fan, so plan to clean dust from the heatsink periodically and be ready to replace the fan if it becomes noisy or fails.

What limit shows up first under sustained load on this 3 GB GDDR5 card?

The 3 GB frame buffer and 134 GB/s bandwidth will saturate before the 768 CUDA cores, capping large-model performance in extended renders.
