New fanless PoE for a UniFi house, not a used 48-port Catalyst: Switch Ultra
If the house is already UniFi, buy new fanless PoE instead of a used 48-port Catalyst. The Ultra 60W is the quiet eight-port box on the UI store.
This is not a rewrite of cheap PoE for two APs. That piece still defaults to the TL-SG1005P. This note is the UniFi-already-in-the-house replacement for a used Catalyst PoE.
USW-Ultra-60W: $159 / $171 surcharge-incl. on store.ui.com, 22 Aug 2026. 52 W PoE with the 60 W adapter; 42 W on PoE++ in; 17 W on PoE+ in; 8 W on PoE in (Streakwave / UI note). Fanless. Device draw is small; the PoE budget is the wall number. USW-Lite-8-PoE is the smaller sibling: $109 / $117 surcharge-incl. UI store. Datasheet: max device 8 W, 52 W PoE budget, fanless, external 54 V / 60 W. Already in the cheap-PoE guide, not the hero here. USW-Ultra without PSU: Micro Center $129.99 (SKU 861328). PSU not included. Easy to get wrong.

Skip
Skip the used 48-port Catalyst PoE. The ports are lovely. The fans, the 208 V aisle, and the SmartNet story are not. See used vs new, brick rule. Skip the Micro Center Ultra if you don't already have the PSU. Skip this whole page if you are not already UniFi; go back to cheap PoE.
