Power, In Real Terms

Watts are an abstract unit until you compare them to something you already know. Here's every product's power draw next to two references: an average home, and an EV battery pack.

Our two reference points:
🏠 An average home draws about 1,200 watts continuously (fridge, HVAC cycling, electronics, lighting — all running at once).
🔋 An EV battery pack holds about 90 kWh of energy — enough to drive roughly 250–300 miles.

Item	Power Draw	Vs. an Average Home	Runtime on One EV Battery
NVIDIA GeForce RTX 4090	450 W	38% of a home's continuous draw	200 hours (8.3 days)
NVIDIA RTX 6000 Ada Generation	300 W	25% of a home's continuous draw	300 hours (12.5 days)
NVIDIA L40S	350 W	29% of a home's continuous draw	257.1 hours (10.7 days)
NVIDIA H100 SXM5	700 W	58% of a home's continuous draw	128.6 hours (5.4 days)
NVIDIA H200 SXM	700 W	58% of a home's continuous draw	128.6 hours (5.4 days)
AMD Instinct MI300X	750 W	63% of a home's continuous draw	120 hours (5 days)
8-GPU Rack Server Chassis (dual EPYC, NVLink backplane)	1,600 W	133% of a home's continuous draw	56.3 hours (2.3 days)
InfiniBand NDR Switch (400 Gb/s per port, networking for real clusters)	750 W	63% of a home's continuous draw	120 hours (5 days)
Dual AMD EPYC 9005 Server, up to 6 TB DDR5 ECC RAM	900 W	75% of a home's continuous draw	100 hours (4.2 days)

What About a Full Build?

Startup Build (CPU/RAM server + 1 GPU)

1,350 W total — a little more than one average home's continuous draw.

One 90 kWh EV battery could run it for about 66.7 hours (~2.8 days).

Mid-Size Build (2-node, 16x H100 cluster)

15,150 W total — about the continuous draw of 12.6 average homes running at once.

One 90 kWh EV battery would only run it for about 5.9 hours — real clusters need real, continuous grid power, not batteries.
