Review on 🎮 High-performance MSI MPG Z590 Gaming Carbon WiFi Motherboard: ATX, 11th/10th Gen Intel Core, LGA 1200 Socket, DDR4, PCIe 4, CFX, M.2, USB 3.2 Gen 2, Wi-Fi 6E, DP/HDMI, Mystic Light RGB by Robert Grimm

I bought two of these motherboards. Both have the same problem. I am using a Corsair H115i liquid cooler. You must use a USB cable to connect to the JUSB connector on the motherboard. However, it sometimes disconnects and reconnects after logging in. If the CPU is heavily loaded, this situation is more likely. So I think the USB power supply of this motherboard is unstable. And I also replaced the H115i with a new one. The same problem still exists. So I can be sure it's a motherboard issue. Since it won't be that random, both motherboards have this problem. The second problem is that when I use a portable hard drive to write large files, because the USB port is used, there is a heavy load on the hard drive. During this time, my wireless mouse and wireless headset (USB connection) experience intermittent problems. I contacted MSI and they asked me to try the beta version of BIOS version 1.3. I still can't solve this problem. In the end they asked me to send it to them for repair. But I don't do that, because this is not an isolated case. That's why I choose to return.
