Cited public information, not purchasing advice. Onboard NIC silicon and BIOS can differ between production batches of the same model name — confirm the revision you receive (
lspci -nn) before relying on a NIC or passthrough claim. Idle draw depends on OS, mains voltage (120 V vs 240 V) and power tuning (powertop).
