TechSellerUSA supplies genuine Supermicro hardware - server motherboards, barebone chassis, complete systems, backplanes, power supplies and spare components. New and certified refurbished, tested, for custom builds, storage servers and GPU platforms.

Why Supermicro for Custom Builds

Supermicro is the platform of choice when an off-the-shelf server from a tier-one vendor does not fit the requirement. Its motherboards follow standard and proprietary form factors across an unusually wide range of socket, drive bay and expansion configurations, which makes it the practical option for storage-dense builds, multi-GPU systems and appliances. It is also the most cost-effective route to a given specification when vendor support contracts are not required.

Board, Chassis and Backplane Matching

A Supermicro build is only as correct as the match between motherboard form factor, chassis, backplane and power supply. Drive backplanes in particular determine whether a chassis supports SAS or SATA, expander or direct-attach, and this cannot be changed later. Browse all server motherboards and servers, or contact us with your requirement for a verified build list.
