Power Supply for MSI MAG274UPF

My monitor randomly lost power yesterday and I can not get it to turn back on. I believe it's the power adapter and not the monitor itself. I have had no issues in the year I've had this monitor.

Can you advise which USB C power item you use on your monitor or a regular power adapter you can buy online? All the ones I can find are over $100 that can't be right?!
