PNY RTX A400 4GB GDDR6 workstation
The Ampere-based RTX A400 fits into a single-slot, low-profile design with a 50W power draw, making it viable for compact workstations where space is at a premium. Its quad Mini DisplayPort 1.4a outputs enable multi-monitor setups for productivity, while the active fan cooling sustains clock speeds up to 2540MHz. This card is best for office professionals and financial analysts needing reliable, multi-display support in small-form-factor PCs, not for AI or content creation workloads.
