Thor’s reputation and technical leadership culminated in a landmark partnership in 2019 with Harvey Norman, Australia and New Zealand’s largest electronics retailer. This collaboration led to the design of the Apex and Alpha ranges, now comprising over a dozen models tailored to consumer needs.

These included slim inline filters for TVs and soundbars — products that resonated with modern home entertainment trends — and full-sized boards for more demanding setups. Harvey Norman also stocked the Prodigy range, Thor’s premium line featuring patented non-sacrificial surge circuits.
