A silly power question

Apologies, this probably seems like a silly question but as I'm not 100% sure, I thought i'd ask.

I'm building a new homelab based on a ultra low voltage Xeon processor (25w TPD!) - it'll be on 24/7.

The lowest wattage PSU's I can find are circa 300W.

If my server is say, consuming 30W's of juice, from the 300W PSU, does the PSU only draw 30W from the wall, or does it draw 300W regardless of how power hungry the components are?

Cheers,

David
