Desktop graphics cards from CSSi South Africa drive gaming, content creation, CAD, AI on-device inference and workstation visualisation. As an authorised distributor for NVIDIA GeForce, AMD Radeon and ASRock partner cards, CSSi supplies discrete GPUs across the full price-performance spectrum with ZAR pricing, a best-price guarantee and Africa-wide delivery.
Buyer’s guide
Match the GPU to display target and workload. 1080p high refresh and 1440p gaming run comfortably on mid-range cards; 4K gaming, ray-tracing and AI workloads need higher-tier silicon with more VRAM (16 GB+). Confirm PCIe slot generation, physical card length against your case, recommended PSU wattage and 8-pin or 12V-2x6 power connectors. For content creation and AI inference, prioritise VRAM capacity and CUDA/ROCm support; for esports and competitive gaming, prioritise high frame-rates and low latency over absolute resolution.
Use cases
Gaming at 1080p/1440p/4K, 3D rendering (Blender, V-Ray), video editing (DaVinci Resolve, Premiere Pro), AI image and language inference (Stable Diffusion, local LLMs), CAD and engineering visualisation, streaming and broadcast, and VR. For datacentre AI training and VDI, see Server GPUs. Pair with Desktop CPUs and Memory for balanced builds.
Why buy GPUs from CSSi
Authorised-channel stock with full manufacturer warranty (typically 3 years on NVIDIA partner cards and AMD Radeon), ZAR invoicing, channel rates for resellers, and pre-sales advice on PSU sizing, case fitment and platform compatibility.
Frequently Asked Questions
How much VRAM do I need?
8 GB is the floor for 1080p gaming in 2026; 12 GB is comfortable for 1440p; 16 GB+ is recommended for 4K, modern ray-tracing and any AI inference work. For local LLMs, 24 GB unlocks larger models.
What PSU wattage do I need?
Match to the GPU’s recommended minimum and add 100–150 W headroom. High-end cards typically require 750–1000 W 80 PLUS Gold or better PSUs with the correct 12V-2x6 cable.
Will the card fit my case?
Modern flagship cards are 320–360 mm long and 3 to 4 slots thick. Measure your case’s maximum GPU clearance and check slot count before ordering. Compact cases may need a smaller model.
What warranty applies?
Typically 3 years manufacturer warranty on NVIDIA partner cards and AMD Radeon, with RMA handled by CSSi in South Africa.
