GPU host finder
Pick the card you want to run and we list the cheapest used servers whose chassis is confirmed to host it: full-height/full-length PCIe slots, aux GPU power, and PSU headroom. By default these are bare hosts (bring your own card); use the toggle to include servers that already ship with a GPU.
4× RTX 4090 (24 GB · 450 W · 3-slot). 24GB Ada flagship, the fastest consumer local-LLM card. Up to 450W via 12VHPWR (needs a 3x/4x 8-pin adapter or an ATX 3.0 PSU); most AIB coolers are 3.5-4 slots, so clearance is tight -- rare in rack chassis, better in a tower.
Host needs: ≥12 full-length PCIe slots · aux GPU power · ≥2650 W PSU. 3-slot card: 3 slot positions reserved, verify physical clearance.
Idle power below is the empty chassis. Add ~1800 W under load once the cards are installed (4× 450 W), roughly $1,892/yr extra at full tilt 24/7.
No live listings currently confirm all of these requirements. Try fewer cards, or browse the GPU-ready lens.
Compatibility is from the platform spec database (slot geometry, aux power, PSU rating). Always verify the exact riser/slot configuration of the specific unit before buying. Power cost shown at 12¢/kWh idle, 24/7.
