Nobody appeared better-prepared for Intel's upcoming 6th-generation CPU launch than ASRock, with a total of six Z170 models on display and a few B's and H's in the mix. The Z-models include advanced features, such as USB 3.1 on all but the low-cost Pro4.

Top models including the Z170 Extreme7 provide top features such as triple 32 Gb/s M.2 connectors, which implies that additional parts such as third-party PCIe bridges are in play. Unlike its competitors, ASRock targets gamers with an optimized feature set at reduced cost. The Fatal1ty Z170 Gaming K6 topped a list that also includes the Wi-Fi-enhanced Fatal1ty Z170 Gaming-ITX/ac and lower-model Fatal1ty H170 Performance.

ASRock even had something on the budget menu for LGA 1151 business system builders in the B150M-HDS/D3 and H110M-HDS/D3. Both of these boards are one slot shorter than the Micro ATX standard, but they still bear that name because people have long forgotten Flex-ATX.
