We finally have a confirmation of Z390 chipset supporting existing Coffee Lake S CPUs. SuperMicro Z390 This is the first trace of SuperMicro's upcoming Z390 motherboard (C9Z390-CG-IW). What is particularly interesting about this leak is the fact that this motherboard was equipped with Core i7-8700T processor, the low-power 6-core CPU already available in stores. Update: we also have a proof of Z390 supporting Core i7-8700K (added below). This means that Z390 will support both upcoming 8-core and existing 6-core 8th Gen Core CPUs. In other words, the Z390 has the same LGA1151 socket as other 300-series motherboards.
