Dell OptiPlex 3050 Small Form Factor upgrades

Released 2017 · on sale

SFF chassis: only half-height (low-profile) PCIe cards fit (1x PCIe x16 Gen 3 + 1x PCIe x1). The ~200 W PSU is Dell-proprietary, so gaming GPU upgrades are severely limited. Chassis 290 x 93 x 292 mm. Intel Optane acceleration needs a 7th-gen Core CPU, Intel RST 15.5+ and Windows 10 64-bit. No SD card reader.
