How well does Supermicro's "pint-sized Powerhouse" stand up to scrutiny? The mini-ITX form factor continues to get more powerful as competition between AMD and Intel has driven up processor core counts over the past few years. With Intel’s newest Core i9 9900K it is now possible to pack 8 cores and 16 threads into a diminutive mini-ITX motherboard. More cores mean more power consumption so concerns about reliable power delivery and quality construction are paramount, concerns Supermicro hopes to allay with the SuperO C9Z390-CG-IW.
