Lenovo ThinkCentre M90s G3 (Intel Core i7) Desktop PC

Description

Enterprise-Class 12th Gen Performance

The Core i7-12700 brings 12 cores (8 performance + 4 efficiency), 20 threads, and a boost frequency of 4.9 GHz, backed by Intel UHD Graphics 770 and a 25MB Intel Smart Cache. This is a full-desktop 12th Gen Alder Lake processor — substantially more capable under sustained multi-threaded load than H-series mobile chips used in competing SFF machines, and well-suited to demanding business applications, local virtualisation, and data-intensive workloads. The 16GB DDR5 ships across two of four U-DIMM slots with a generous ceiling of 128GB maximum.

Exceptional Expandability for an SFF Machine

Where most SFF desktops offer one or two expansion slots, the M90s Gen 3 provides four: one PCIe 4.0 x16 full-bandwidth slot, one PCIe 4.0 x16 (x4 signal) slot, and two PCIe 3.0 x1 slots — all low-profile. Storage is equally well-provisioned: two M.2 SSD slots (up to 2TB each), a 2.5″/3.5″ HDD bay, and an additional 2.5″ HDD bay, supporting up to four simultaneous storage devices. A DVD-RW optical drive is included. The 380W 92%-efficient internal PSU provides ample headroom for a discrete GPU or additional drives.

Connectivity & I/O

Front ports include 1x USB-C 3.2 Gen 2 (data transfer and 15W charging), 2x USB 3.2 Gen 2 Type-A, 2x USB 3.2 Gen 1 Type-A, a headphone/mic combo jack, and a dedicated microphone port. The rear adds 4x USB 3.2 Gen 1 Type-A, HDMI 2.1, 2x DisplayPort 1.4, Gigabit Ethernet (RJ-45), and a line-out jack — supporting three simultaneous displays from the onboard video outputs. Wi-Fi 6 and Bluetooth 5.1 are built in, with a Wi-Fi 6E vPro-compatible adapter available on the platform for organisations requiring Intel AMT remote management.

Security, Manageability & Build

ThinkShield covers the full enterprise security stack: discrete TPM 2.0, Smart USB Protection, individual USB port disablement, hard disk password, power-on password, cover tamper detection, Kensington lock slot, and padlock loop. The platform supports Intel vPro with Intel AMT when paired with a vPro-compatible wireless adapter, enabling out-of-band remote management for IT deployments. MIL-STD-810H military durability testing is passed across all major environmental stress categories.

💡 The four PCIe expansion slots and four-drive storage bays make this one of the most expandable SFF machines in its class — businesses needing a capture card, RAID controller, dedicated NIC, or discrete GPU can accommodate all of these simultaneously.

⚠️ All expansion slots are low-profile (max 155mm length, 70mm height). Full-height or double-slot cards will not fit. Confirm GPU dimensions before purchasing a discrete card for this machine.
