Does a oversized PSU still draw all power?

[ricno]

Hello,

I have a question in general, perhaps a stupid one!

If I buy a too large power supply unit for my system, and the components does only need, say half, of the power available from the PSU, will my system still draw all power, and wasting energy and money?

Nothing to worry about. Your system will draw as much power as it needs, no more.
