The savings over alternating current (AC), the current power standard, are considerable. With AC, there are 4 wires while DC has two. So there is considerable wiring savings in an all-DC facility. Also, with higher voltage comes a lower current and current is what generates heat. So data centers that can run on 800VDC can run cooler.
That translates to a 50% to 80% reduction in copper usage and an 8% to 12% reduction in annual energy-related OpEx through lower conversion and distribution losses. AI-first facilities can see a $4 million to $8 million in CapEx savings per 10 MW build by reducing upstream AC. For a one-gigawatt data center, you’re saving a several million pounds of copper wire.
The push reflects a fundamental change in data-center power requirements. AI accelerators are being deployed in increasingly dense configurations, driving power consumption per rack higher and making traditional low-voltage AC distribution more difficult to scale.
