Frequently asked questions
Does the HP EliteDesk 800 G3 Mini or the HP EliteDesk 800 G4 Mini use less idle power?
The HP EliteDesk 800 G3 Mini idles at ~12 W idle (120 V); ~51 W max load on its 65 W adapter (wall-measured); the HP EliteDesk 800 G4 Mini idles at ~11–12 W idle (six-core config, 120 V wall) (wall-measured). On the cited lower-bound figures, the HP EliteDesk 800 G4 Mini draws less. Idle varies with OS, 120 V vs 240 V mains and power tuning, so treat these as the third-party measured numbers, not a guarantee for your exact unit.
HP EliteDesk 800 G3 Mini vs HP EliteDesk 800 G4 Mini: which has the better NIC for Proxmox?
HP EliteDesk 800 G3 Mini NIC: 1× 1GbE Intel I219 (rated solid). HP EliteDesk 800 G4 Mini NIC: Intel i219LM 1GbE (vPro/AMT) (rated solid). Intel i226 is the chipset to want; i225 has a documented dropout history and Realtek RTL8125 works on Linux/Proxmox but not VMware ESXi. Confirm the silicon on the unit you receive with lspci -nn.
Which is the better homelab / Proxmox box, the HP EliteDesk 800 G3 Mini or the HP EliteDesk 800 G4 Mini?
HP EliteDesk 800 G3 Mini: 7th-gen HP 1L; ~12 W idle right in the expected band, solid I219 NIC. HP EliteDesk 800 G4 Mini: Six-core 8th-gen Intel idling at a wall-measured 11–12 W with a solid Intel i219LM NIC and dual M.2 slots makes a tidy, low-power Proxmox node. These are our editorial verdicts derived from the cited fields above — not a spec.
Cited public information, not purchasing advice. Idle draw depends on OS, mains voltage (120 V vs 240 V) and power tuning (powertop); onboard NIC silicon can differ between production batches of the same model — confirm with
lspci -nn before relying on a NIC or passthrough claim. Full per-model detail and every source on the model pages.
