When I created my digital imaging setup, power provisioning was part of the workflow. My machines, custom-built Wintel workstations, ran hot, loud, and often. They thrived on amperage. Parallel MATLAB jobs, multi-threaded Lightroom tasks, Helicon Focus stacks, and panoramic stitching operations were all hungry in the same way: they wanted every CPU core lit up, every fan spinning, and every watt accounted for.
To keep them happy, I fed them accordingly: 20 amp outlets, 2500 KVA UPSs, and an ambient hum that said “server room” more than “studio.” The UPSs weren’t just insurance—they were load-bearing infrastructure.
Then I moved to Apple Silicon. I started with the M2 Ultra, then the M3 Ultra, and now the M4 machines. The transition was motivated by curiosity more than necessity, but the result has been quietly transformative. My code still runs in parallel. My images still get stacked, stitched, and sorted. But the electrical load has vanished into a kind of silent efficiency.
I haven’t needed to think about amperage draw. The UPSs now seem theatrical. Apple’s chips don’t just sip power—they treat it like a precious commodity. And yet, they deliver—often faster than the machines they replaced, and always with less fuss.
The lights no longer flicker when I launch a job. The fans stay off unless summoned by something truly arcane. This shift doesn’t feel like a compromise. It feels like an overdue liberation—from BTUs and from the notion that performance must be noisy and power-hungry to be real.
I still run the same jobs. I just no longer need a substation to do it.
