Dell OptiPlex 3080 Micro

The OptiPlex 3080 Micro (2020) is Dell's entry 10th-gen Comet Lake Micro, built on the Intel B460 chipset. Dell lists only 35 W T-series chips, from the Celeron G5900T up to the eight-core, sixteen-thread Core i7-10700T, and raises the official memory ceiling to 64 GB across two DDR4 SO-DIMMs (2666 MHz, or 2933 MHz with the i7). Storage is one M.2 2230/2280 NVMe slot plus a 2.5-inch SATA bay. It runs from a 65 W adapter with a 4.5 mm barrel, uses a Realtek RTL8111HSD gigabit NIC, and has no vPro. Front USB is 5 Gbps Type-A only, and the rear has HDMI 1.4 and DisplayPort 1.4 plus an optional VGA/DP/HDMI 2.0/serial module. A good quiet host for containers or a media server when you do not need Intel AMT, an Intel NIC or a second M.2 slot.

Buying guide

Which one to buy

Oct 4, 2026

265 OptiPlex 3080 Micros are listed, and most complete units sell for about $160–220 delivered. The six-core i5-10500T is the common, sensible config; check the CPU, since dual-core Celeron and quad-core i3 units share the same case, and look for 8 GB or more plus an NVMe SSD. Every 3080 Micro runs a 35 W T-series chip from Dell's 65 W adapter with a 4.5 mm barrel, which many off-lease units leave out. Treat 'Win 11 Pro' in a title as a claim to confirm, and be wary of identical titles from different sellers.
