Tired of the rat's nest of AC adapters behind your rack? There's a better way. This episode breaks down how to build a centralized DC distribution system for your homelab — one high-quality power supply feeding a fused distribution panel, with tiny DC-DC converters handling oddball voltages. We crunch the numbers on efficiency (88% vs 65% for wall-warts), heat reduction, UPS runtime gains, and total cost. Plus we cover the gotchas: ground loops, inrush current, and how to make sure your setup is safe, not sketchy. If you've got Raspberry Pis, switches, and routers all running on individual bricks, this architecture saves money, space, and your spouse's patience with fan noise.
