Intel's Z390 platform continues to be a firm favourite with the DIY enthusiast audience, in large part because of the excellent performance delivered by the Core i9 9900K. That processor, however, is more power-hungry than its predecessors and motherboard vendors have necessarily responded with higher-end power circuitry. MSI's Enthusiast Gaming (MEG) ACE motherboard crystallises this approach with 12 phases purely aimed at powering all eight cores with overclocking.
The MSI MEG Z390 ACE is designed to be a high-end performer loaded with connectivity and features, leading MSI to make bold design decisions. One of those is completely doing away with the integrated graphics to maximise board space for connectivity and CPU VRMs; things MSI believes the overclocking audience demands.
MSI hasn't just got tunnel vision on VRMs though, MSI has gone all out on connectivity with a hefty eight USB 3.1 10Gbps ports, three M.2 slots, four RGB headers and both wired and wireless networking solutions. Troubleshooting and overclocking features have been implemented generously as well: a clear CMOS button, onboard diagnostic LEDs, debug code reader, BIOS flashback and VRM monitoring sensors all come included.
MSI has managed all of the above while still coming to market at a lower or similar price point to many of its rivals. On paper at least, MSI looks to have pulled it off, but let's find out how the MEG Z390 ACE stands up to scrutiny.
