this is kind of a noob question:
I have a power strip (extension cord from my wall AC outlet) that is rated for 250V 10A. Over this power strip i'm connecting a power supply that gives an output of 12V 20A.
What's the relation between the power strip current rating and the PSU one?. I mean, how could you state the needed value for the power strip based the PSU current rating?
It's enough to just calculate the power consumption in Watts on the PSU (Vout * Output current) being lower than the one rated for the power strip?
(I'm not connecting anything else besides the PSU on it).
