Powering 4x 1200W GPUs: why a 15A outlet barely cuts it and you need a PDU
TheZachMueller · x · 2026-09-25
For developers running multiple 1200W-class GPUs locally, the author explains PDU selection: a standard 15A/120V outlet tops out around 1440W continuous — barely (and sketchily) enough for 4x RTX 6000 Max-Q GPUs plus accessories. The safer route is 20A or 30A 240V circuits feeding a PDU. He shares photos of the PDU he uses versus the one he actually wants.
