UniFi Pro 24 PoE vs Pro Max 24 PoE

Both switches occupy the same slot in a UniFi rack: a 1U, 24-port, Layer 3 PoE access switch with dual 10G SFP+ uplinks. The Pro 24 PoE is the all-gigabit default; the Pro Max 24 PoE is the multi-gig variant of the same design. They are not aimed at different network sizes — they are aimed at different port-speed needs.

If you are still mapping the lineup, start with how to choose a UniFi switch or browse the Switches hub. The decision here comes down to one question: do any of your devices need more than a gigabit?

This is the entire reason the Pro Max exists. Wi-Fi 6E and Wi-Fi 7 access points routinely push past a single gigabit on the wired side, and a 2.5 GbE uplink to the AP removes that bottleneck. The same applies to 2.5 GbE NAS boxes and workstations. If none of your devices exceed 1 Gbps, the all-gigabit Pro 24 PoE loses nothing by comparison.

Note that only a third of the Pro Max's ports are 2.5 GbE — it is a mixed switch, not an all-multi-gig one. If your multi-gig footprint is small and you do not need 24 ports, a compact Flex 2.5G 8 PoE can cover it instead; that trade-off is laid out in Flex 2.5G vs Pro Max 24 PoE.

The headline 400 W is the same number, so total PoE capacity is not the differentiator. What changes is how many ports can each pull the top PoE++ tier at once. With 16 PoE++ ports versus 8, the Pro Max suits installs dense with power-hungry endpoints; the Pro 24's eight PoE++ ports are plenty for a typical mix of APs, cameras, and phones. Either way, add up your devices' draw against that shared 400 W — it is the real ceiling, as the buying guide explains.

The 112-vs-88 Gbps gap simply tracks the 2.5 GbE ports — a bigger fabric is needed to switch faster ports at line rate, and it is not a reason to buy the Pro Max on its own. The part that matters for your topology is the uplinks, and there both are the same: two 10G SFP+ ports feeding a 10G core or an aggregation switch. Neither switch is your aggregation layer — both are access switches that uplink at 10G.

This is the clarifying point. Because Layer 3, the 10G uplinks, the 400 W budget, and the 1U form factor are shared, the Pro 24 PoE is not a "lesser" switch — it is the same switch without multi-gig access ports. If you do not have multi-gig devices, you give up nothing by saving the $100. If you do, the Pro Max is the only one of the two that serves them.

The two switches rarely compete for the same buyer once you have written down whether anything on your network exceeds a gigabit. Here is how the decision breaks.

Buy the Pro 24 PoE if:

• Your network is gigabit. Every wired device tops out at 1 GbE, so 24 gigabit PoE ports cover the floor with nothing wasted.
• You want Layer 3 and 10G uplinks at the lowest 24-port price. Routing, dual 10G SFP+, and a 400 W budget for $699.
• Your PoE mix is typical. APs, cameras, and phones sit comfortably inside eight PoE++ ports and the shared 400 W.

Buy the Pro Max 24 PoE if:

• You run Wi-Fi 6E or Wi-Fi 7 APs. Their wired throughput can exceed 1 Gbps; the eight 2.5 GbE ports remove that bottleneck.
• You have 2.5 GbE clients or NAS. Multi-gig workstations and storage get their full speed.
• You pack in high-draw PoE devices. Sixteen PoE++ ports drive more 60 W endpoints at once.
