> single DC rack might use (max 25kW, someone correct me)

25kW? Don't tell me your engineers used that number in their calculations.

Reality:

GB200 NVL72 - 120 kW per rack

GB300 NVL72 - 150 kW per rack

Weight - 3,000–3,500 lbs per rack

Cost of liquid cooling on Earth - $50,000 per rack

by 2027 the new 800V-HVDC will be deployed - 1 MW per rack

I'd never imagined I'd be providing free engineering consultations to billionaires.

Thanks!

There's a reason why I phrased it as uncertainly as I did:

I (ironically given context) googled something like "maximum power draw of data center rack" and the first few results all agreed with each other at 25 kW.

I never thought I'd be mistaken for a billionaire, but there we go.

I'm kinda curious now, which billionaire did you mistake me for?
