AM4, mATX, DDR4, 4 Memory slots
Budget Motherboards
8 budget motherboards from MSI, GIGABYTE, ASUS and more. Most cost $83 to $126, and half cost less than $99.
Boards whose listing states DDR4 memory and a micro ATX layout. DDR4 is the cheaper memory and a smaller board is the cheaper board, so this is where a build saves money without losing a graphics slot.
We do not pick by hand: a motherboard is here because its listed specs pass the checks.
