Frequently asked questions
ATX, micro-ATX or mini-ITX?
ATX gives the most expansion slots and fits mid and full towers. Micro-ATX is shorter and fits smaller cases while keeping four RAM slots on most boards. Mini-ITX is for compact builds and usually has two RAM slots and one PCIe slot.
Do I need a BIOS update for a new CPU?
Sometimes. If a board shipped before the CPU launched, it may need a BIOS update. Most current AM5 and LGA1851 boards support BIOS flashback without a CPU installed. The listing links to the manufacturer support page so you can check.
What is the difference between B850 and X870E?
Both are AM5 chipsets. X870E boards offer more PCIe 5.0 lanes, more USB4 ports and more M.2 slots; B850 covers most gaming builds at a lower price. Compare the slot counts on each listing.
