Oh look … I wonder where they took the idea from?
Taken from TPU … BIOSTAR today introduced a pair of Socket LGA1200 motherboards based on the Intel Z490 chipset, the Racing Z490A-SILVER (ATX) and Racing Z490T-SILVER (Mini-ITX). Both appear to be middle-of-the-market products positioned below the Racing GT EVO series from the company, competing with the likes of the ASRock Steel Legend and ASUS TUF Gaming series. Z490A-SILVER draws power from a combination of 24-pin ATX and 8+4 pin EPS power connectors, conditioning power for the CPU using a 12+2+2 phase VRM. You get a pair of reinforced PCI-Express 3.0 x16 slots (electrical x16/x4), two M.2-2280 slots with PCI-Express 3.0 x4 wiring, and connectivity that includes a 1 GbE interface pulled by an Intel i219-V controller, and a 6-channel HD audio solution based on the Realtek ALC1150 codec.
The Racing Z490T-SILVER Mini-ITX motherboard features a conventional 24-pin + 8-pin power input, a 7+2+1 phase CPU VRM, a pair of DDR4 DIMM slots, a reinforced PCI-Express 3.0 x16 slot, and connectivity that includes four SATA 6 Gbps ports, an M.2-2280 slot (SATA 6 Gbps + PCI-Express 3.0 x4 wiring) on the reverse side of the PCB, 1 GbE based on Intel i219-V, and preparation for Wi-Fi 6 (you drop in your own Intel AX200-series card on a CNVi slot). The comapny didn’t reveal pricing.
