What is the power budget for that DGX. The power budget for ISS is 75–90 kW. If your DGX fridge needs more power, it will need similar capacity of solar and radiators.
> In 2027, the unified approach will almost certainly be taken to new levels as NVIDIA's “Kyber” system will launch, with 576 GPUs in a single rack requiring a whopping 600 kW, equivalent to delivering enough power for 500 US homes into the space of a filing cabinet.
That fridge needs 600 kW of power. That will require 6x more solar panel space than the ISS and 6x more radiators. It's not about the volume of the object but rather its power and heat budgets.
If that fridge can reject all of the heat from the rack in space, it will work much better on earth and all the data centers would be using that fridge instead of their cooling towers and AC.
DGX is only 10,2 kW. But also only 8 H200s. Kyber seems a bit more power efficient (per-GPU) but requires much more power for a single unit. With that power requirement it doesn’t seem like it will fly.
10 kW is something that could be household load (a backup generator for a home when there's a power outage).
If one could put a DGX in my basement without issue (there's an idea - would you trust me with a DGX rack in my basement for six months for winter heating? https://www.cnbc.com/2026/01/27/data-centers-ai-district-hea... ), what is the value of shipping it into space? Granted, I couldn't afford a DGX in my basement... but it's not one DGX that you're putting in a datacenter, but rather racks upon racks of aisles upon aisles.
