Verdict

The ASRock Z87 OC Formula/ac is a high-performance E-ATX motherboard designed for extreme overclocking, featuring a robust 12-phase power delivery system, 802.11ac Wi-Fi, and a hybrid 'Twin-Power' cooling solution that supports both air and water cooling for the VRMs. Key specifications include support for Intel 4th Gen Haswell processors (LGA 1150), four DDR3 slots reaching up to 3000MHz+ (OC), and four PCIe 3.0 x16 slots for multi-GPU setups. Its primary advantages are the unique waterproof Conformal Coating, a built-in Status OLED for real-time monitoring, and specialized 'NickShih' overclocking profiles. However, notable drawbacks include its large E-ATX footprint, which limits case compatibility, and the lack of support for more than dual-card SLI despite having four x16-length slots.
