Description
The Leadtek NVIDIA RTX A400 brings the power of the Ampere architecture to a remarkably small footprint. Featuring 768 CUDA cores and 4GB of GDDR6 memory, this single-slot card is designed for professionals who require reliable performance without the thermal or spatial demands of high-end GPUs. Its 50W TDP ensures compatibility with almost any workstation power supply while providing a significant uplift in computational efficiency.
This product is for:
This card is engineered for specific professional demographics:
- CAD and BIM designers requiring stable drivers for 2D and entry-level 3D modeling.
- Financial analysts and traders who need to drive up to four 5K displays simultaneously from a single low-profile slot.
- Small Form Factor (SFF) enthusiasts building compact workstations for media playback or edge computing.
- Content creators utilizing AV1 hardware decoding for efficient high-resolution video workflows.
- IT professionals seeking a long-lifecycle, certified GPU for corporate deployments.

In practice, the RTX A400 excels in stability and multi-tasking. The active cooling system maintains optimal temperatures even during sustained rendering tasks, while the four mini-DisplayPort 1.4a connectors provide flexible display configurations. Users will find the installation seamless in both standard ATX and slimline chassis, thanks to the included full-height and low-profile brackets. The addition of AV1 decoding support significantly improves the experience of streaming and viewing high-quality video content.
Compared to previous generation entry-level cards like the NVIDIA T400 or T600, the RTX A400 introduces dedicated RT and Tensor cores, enabling real-time ray tracing and AI-augmented features that were previously unavailable at this power tier. Unlike consumer-grade GeForce cards, the Leadtek RTX A400 uses professional drivers certified for stability in applications like AutoCAD, SolidWorks, and Adobe Creative Cloud, ensuring fewer crashes during critical projects.
Q&A:
Frequently Asked Questions:
- Does the RTX A400 require an external power connector? No, it draws all necessary power (50W) directly from the PCIe slot.
- Can this card drive 8K displays? Yes, it supports up to two 8K displays at 60Hz or four 5K displays at 60Hz via mDP 1.4a.
- Is the RTX A400 suitable for gaming? While it can run light titles, it is optimized for professional applications and stability rather than high-frame-rate gaming.
- What is the benefit of the Ampere architecture in this model? It provides 2nd Gen RT Cores and 3rd Gen Tensor Cores, bringing AI and ray-tracing capabilities to the entry-level professional segment.
- Does it support AV1? The RTX A400 includes a dedicated NVDEC engine that supports AV1 hardware decoding for modern video formats.
