Question about MSI Z270 Tomahawk

I don't know why this is of interest, but MBs usually consume very little power (10-25W). According to the data sheet, the Intel Z270 has a TDP of 6W + a few other components, so I would estimate 10-15W. I don't think you can really check this anywhere.

here you can calculate the consumption of your computer and you will know if your power supply is sufficient or if you need a new one...look here: https://www.enermax.outervision.com/
