VoltTech Computer Co is a professional PC repair and technology services provider based in Pretoria. We specialise in PC repairs, performance optimisation, hardware upgrades, virus and malware removal, and custom gaming PC builds. Whether your computer is slow, overheating, infected, or simply not performing the way it should, we deliver reliable, honest service with clear communication and workmanship you can trust.

VoltTech was built from a lifelong obsession with technology — starting in audio engineering and signal processing, and evolving into high-performance PC design, optimisation, and tuning. For over 25 years, we’ve worked hands-on with hardware at the component level, building and refining systems for demanding 3D modelling, mechanical engineering workloads, content creation, and competitive gaming. We don’t just assemble PCs — we engineer them. Every system is approached like a performance lab: thermals analysed, airflow optimised, power delivery stabilised, overclocks dialled in properly, undervolts tuned for efficiency, and stress-tested for real-world stability — not just synthetic numbers. From workstation reliability to record-chasing gaming benchmarks, VoltTech delivers measured, benchmarked, and properly tuned performance. No guesswork. No bottlenecks. Just hardware pushed to its full, stable potential.
