Does MoBo wattage affect wattage.

[GeneralMercer]

My mother board-ga b250m ds3h shows 700 in front of wattage(no unit mentioned) is it in watts ?do I require a more than 700W psu?

this is what the box looks like normally, if not the same take a picture because I never seen a "wattage" indicator on the front of a motherboard box.
Note: the only indicator of wattage would be the Max TDP it can handle and there is no 700w cpus yet

In the olden days you could find boards that used ~25W. This was back when there was a north and south bridge. Now, nearly everything is on the CPU and there is no north/south bridge on the board. There is a "media hub" that handles the USB and other ports, but it can't use that much power. More so if they are using a better process technology compared to back than. I haven't seen any hard numbers on the boards power draw, but I would expect the draw to be closer to 5-10W, not 25W. There is no way you have a board that needs 700W.
