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. Servers are sold without the GPU; this finds the host.
4× RTX 3090 (24 GB · 350 W · 3-slot) — 24GB consumer flagship. 3-slot: verify physical clearance in 2U.
Host needs: ≥8 full-length PCIe slots · aux GPU power · ≥2150 W PSU. 3-slot card: adjacent slots reserved, verify physical clearance.
