The Power Chain: Grid to Chip

Before a data centre executes a single instruction, its electricity has already been transformed, switched, converted to DC, converted back to AC, distributed and converted again, and every one of those stages takes a cut. The power chain exists for good reason: servers need clean, uninterruptible power, and the availability guarantees that define the sector are delivered here. But the chain's losses run 24 hours a day at the site's full load, and, less obviously, the redundancy that protects uptime quietly pushes every stage toward its least efficient operating point. This lesson follows the electricity from the grid to the chip and shows where the percent-after-percent goes.
