Small startup build
Running DeepSeek V4 Pro
DeepSeek · MIT · 1,600B parameters
The memory math:
1,600B parameters × 2 GB/B = 3,200 GB baseline,
+ 20% overhead for KV cache/context = 3,840 GB minimum required.
Recommended build
4x NVIDIA DGX H200
At 1.6 trillion parameters, even the cheapest workable setup is four full 8-GPU servers. We're showing the honest number rather than a cheaper one that wouldn't actually run the model.
Combined GPU memory
4,512 GB
Total price
$1,396,000
Combined power draw
40.8 kW
Monthly electricity
$5,523
4 × NVIDIA DGX H200 at 10,200 W each = 40,800 W total. Run 24/7, that's 979.2 kWh/day — about the same continuous draw as 33.8 average U.S. homes (~29 kWh/day/home, EIA). Monthly cost assumes 18.8¢/kWh, the 2026 U.S. residential average.
Why more than one unit? This model needs 3,840 GB
of GPU memory, and a single NVIDIA DGX H200 only has 1,128 GB — so
4 of them are cabled together into what's called a cluster: multiple
servers networked together so they act like one much bigger computer than any single box could be.
