| AMD reset bug | — | AMD APU — the Radeon 680M iGPU is subject to the AMD reset bug for VFIO passthrough (GPU fails to reset on VM restart until host reboot). Workaround is gnif's vendor-reset DKMS module; not all APUs are fixed by it. source · 2020-11 |

| Proxmox fit (editorial) | good — Cheap, very efficient ~5–8 W idle Zen3 box for a lightweight Proxmox node, but only 1GbE networking limits it for storage/VLAN-heavy homelab use. | good — 8C/16T of real compute at 20–35 W idle — much more grunt than N100, but higher idle and the AMD reset bug if you want iGPU passthrough. |

Frequently asked questions
Does the Beelink SER5 Pro or the Beelink SER6 Pro use less idle power?
The Beelink SER5 Pro idles at ~5.3–8.2 W idle (wall-measured); the Beelink SER6 Pro idles at 20–35 W idle (wall-measured). On the cited lower-bound figures, the Beelink SER5 Pro 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.
Beelink SER5 Pro vs Beelink SER6 Pro: which has the better NIC for Proxmox?
Beelink SER5 Pro NIC: Gigabit Ethernet (1 GbE) (rated unknown). Beelink SER6 Pro NIC: not independently confirmed. 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 Beelink SER5 Pro or the Beelink SER6 Pro?
Beelink SER5 Pro: Cheap, very efficient ~5–8 W idle Zen3 box for a lightweight Proxmox node, but only 1GbE networking limits it for storage/VLAN-heavy homelab use. Beelink SER6 Pro: 8C/16T of real compute at 20–35 W idle — much more grunt than N100, but higher idle and the AMD reset bug if you want iGPU passthrough. 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.
