The construction of domestic intelligent computing centers is accelerating, computing power chip performance continues to leap, and power consumption per device is rising sharply in tandem. AI server power supply systems need higher power density, more stringent dynamic load response, smaller space occupation, while also taking into account overall system energy consumption metrics.

On September 22, 2026, Intel Connection 2026 grandly opened. As an Intel ecosystem partner, IVS brought multiple EVM Boards for AI servers and other computing platforms to the conference’s “Computing Power - AI Factory Power Supply” exhibition area, joining global industry chain partners to explore the development path of underlying power supply for AI infrastructure.
