I don’t need to build a datacenter, i’m fine with building a rack myself in my garage.

During the last GPU mining craze, I helped build a 3-rack mining operation. Gpus are unregulated pieces of power-sucking shit from a power management perspective. You do not have the power requirements to do this on residential power, even at 300amp service.

Think of a microwave’s behaviour ; yes, a 1000w microwave pulls between 700 and 900w while cooking, but the startup load is massive, almost 1800w sometimes, depending on how cheap the thing is.

GPUs also behave like this, but not at startup. They spin up load predictively, which means the hardware demands more power to get the job done, it doesn’t scale down the job to save power. Multiply by 58 rx9070. Now add cooling.

You cannot do this.
