MSI outs 'world's first' ATX 3.1-ready mobos with extra PCIe juice for power-crazed next-gen GPUs

MSI ATX 3.1.

MSI has outed its new X870 and X870E motherboards for AMD AM5 processors, including the new Ryzen 9000-series chips. The big news is ATX 3.1 support and a big boost in PCIe power supply.

MSI says the boards' new supplemental PCIe Power feature delivers a major boost in overall board and GPU power supply. That could well come in handy, what with expectations of ever greater power draw from upcoming GPUs, particularly Nvidia graphics cards like the rumoured 550 W RTX 5090.
