HP NVIDIA RTX A400 4GB GDDR6 Graphics Card with Mini Bracket & 4x Mini DisplayPort

The HP NVIDIA RTX A400 4GB (AV8J3AA) is a professional-grade graphics card designed for small form factor workstations and business computing environments. Built around 4 GB of GDDR6 video memory, it delivers dependable throughput for professional workflows including CAD visualisation, multi-display productivity, and enterprise graphics tasks that demand driver stability over raw gaming performance. The card ships with a mini bracket, making it directly compatible with SFF and slim desktop chassis where a full-height card would not fit. This design consideration means IT managers and system integrators can deploy it across a wider range of HP and compatible business towers without additional hardware modification. Connectivity is handled by four mini DisplayPort outputs, enabling multi-monitor configurations from a single card. Whether driving a dual-screen productivity setup or an extended four-display workspace, the outputs provide flexible cabling options with standard mini DisplayPort to DisplayPort adapters. The PCIe 4.0 interface ensures the card operates with modern platform bandwidth, reducing any bottleneck between the GPU and the host CPU in contemporary workstation builds. Professional driver support — distinct from the consumer GeForce driver stack — provides a stable, certified software environment well-suited to business-critical applications.
