Gigabyte B850M AORUS STEALTH (AM5/AMD B850/Micro-ATX/Reverse-Connector Design/DDR5 OC/PCIe 5.0/WiFi 7) Review
The Gigabyte B850M AORUS STEALTH, introduced in July 2026, brings Gigabyte's reverse-connector Project STEALTH design to a Micro-ATX form factor for the first time in this generation, following the full-size ATX B850 and X870 STEALTH boards shown earlier in the year. The core concept carries over unchanged at the smaller size: every major connector sits on the back of the board rather than the front, letting cables route behind the tray in a compatible case. This is aimed at small form factor builders who want the same cableless aesthetic the ATX STEALTH boards offer without stepping up to a full-size case.
Gigabyte's specific per-component specifications for this Micro-ATX board weren't broken out in the same detail as the ATX STEALTH models at the time of writing; expect a scaled-down VRM and connectivity set appropriate to the smaller form factor, following the same B850 STEALTH design language as its ATX sibling.
Compatibility and Case Requirements
As with every board in the STEALTH line, this Micro-ATX version requires a case built with matching reverse-connector cutouts and standoffs; a standard Micro-ATX case will not accept the reversed connector layout. Confirm case compatibility specifically for the Micro-ATX form factor before buying, since a case supporting the ATX STEALTH boards doesn't automatically support this smaller version, and vice versa.
Memory and Expansion
Four DDR5 DIMM slots with overclocking support and PCIe 5.0 storage and graphics connectivity carry over from the ATX STEALTH design philosophy, scaled to fit the smaller Micro-ATX footprint with a reduced slot count relative to the full-size ATX boards in the same family.
Design and Build
The reverse-connector layout is identical in concept to the ATX STEALTH boards: cables connect behind the board rather than across its visible face. Fitting this into a Micro-ATX footprint is a genuine engineering challenge Gigabyte hadn't previously solved in this generation, making this board notable specifically for extending the cableless concept into small form factor builds rather than only full-size ATX cases.
