Part numberUSW-Flex-XG
The same part under other regional numbers: USW-Flex-XG-EU, USW-Flex-XG-UK
The short answer
4 10GbE ports in a managed, fanless case are what the Ubiquiti UniFi Flex 10 GbE (US), part number USW-Flex-XG, offers. It is a network switch for a mini PC owner who wants wired 10GbE links between machines, and it has no PoE power to hand out.
Specifications
There are 4 ports at 10GbE and no 2.5GbE or SFP+ ports, so every connection on the switch is a 10GbE port. It is managed, so you can configure it rather than just plug it in. It is fanless, so there is no fan inside it. The PoE budget is 0 W, which means it cannot power PoE devices.

Which mini PCs it fits
The switch has 4 ports at 10GbE and none at 2.5GbE, so what decides fit is the LAN speed of the mini PC you plug into it.
We have not confirmed it fits the Lenovo ThinkStation P3 Tiny Gen 2, because that machine's LAN speed is not confirmed. The same applies to the MINISFORUM AI X1 Pro, whose LAN speed is also not confirmed. Check the LAN speed on each machine's own spec page before you plan around this switch.
Checked against every mini PC sold on amazon.com, from the specifications we hold for each machine.

Before you buy
Before buying, check your mini PC's LAN speed, because we have not confirmed it for the two machines named above. The PoE budget is 0 W, so any PoE device needs another power source. Ubiquiti's own specification page is the place to look for further details.
Common questions
Can this switch power PoE devices?
No. Its PoE budget is 0 W, so it carries data only, and any device that relies on PoE needs a different power source.
Is the Ubiquiti UniFi Flex 10 GbE managed, and does it have a fan?
It is a managed switch, so you can configure it, and it is fanless, so there is no fan inside the case.
Does it fit the MINISFORUM AI X1 Pro?
We have not confirmed it. That machine's LAN speed is not confirmed, so we cannot say whether it fits the switch's 10GbE ports.
