Yeah it does 280w or something like that.
If it's really ~ 280w, that would be over 90% of max - generally it's good
practice to keep the power supply operating below, say, 70% of max. Many
will say it should be in the 50% range.
General, the efficiency of a PS is best around 50% [just means that for the
power requirement for your system, the PS will generate less heat than one
that is operating less efficient].
If nothing else, operating close to the max exposes your system to effects
of spikes in power requirements pushing the load over max. [As noted below,
'max' is really only relevant by 'rail' i.e., 5v, 3.3v, 12 volt rails.]
Here's a calculator to estimate your power requirements.
