AI datacenters explore higher voltage power distribution systems

• Datacenters are testing 800VDC power systems as an alternative to current 48V setups, which could reduce energy lost as heat during conversion from grid power to computer chips.
• The shift would require less copper wiring and special semiconductors called silicon carbide and gallium nitride to manage the higher voltage safely.
• Implementation across the industry could take years because it requires redesigning how power flows through entire datacenter facilities.

AI datacenters are assessing the shift from 48V to 800VDC power distribution architectures. The transition streamlines conversion from grid AC to silicon, reducing heat losses and copper cabling needs, but requires silicon carbide and gallium nitride semiconductors and could take years to implement across datacenter designs.
