Don't state something is "not true" without providing an explanation
to back your point.

Do higher powered PSUs cost more to run because they consume more power?

No, more powerful PSUs will consume around the same amount of power as
lower powered PSUs in any given PC system. Your electricity bill will
not be higher when using a more powerful power supply!

That's what the 80+ rating was all about ; a PSU is over 80% efficient
at any given load.
Most tests will also show that the lighter the load, the more
efficient a PSU is likely going to be.

"Even so, Is Higher Power Better?

Without getting into technical details, the nature of a switching
power supply is that it delivers as much power as is demanded by the
components. This means that when installed in a PC whose components
require 200W, a 400W PSU and a 250W PSU will each deliver 200W."
