May not be the safest bet for the computer you connect to it if you forget and shut off power via the switch ... power draw however will most likely not be a problem.
AH, so what do you mean here--the power switch on the computer? (or the PSU main switch on the back?). I basically have the same setup--a wall splitter at the outlet, which turns the 2 outlets into 6, with the computer/PSU main, display, various peripherals, speakers, phone charger, all plugged in. ...though I also have a separate outlet (which I know to be on a different circuit, though it is shared with some outlets in the main kitchen below...because an earlier owner was nuts) which I can, and sometiems do, use for the computer/PSU alone.
oh, you mean how the OP has that outlet powered through a wall switch. ...what I understood is that the top port on the outlet is not switched, but the bottom one is, somehow? (this confuses me), or the lamp has a seperate on/off switch, located in the floor cable--I think I see it in the photo--which shouldn't be that relevant, I think.
I mean, what is a "welcome light switch?" Is that what people call a wall switch that controls an outlet, usually used for a floor or wall lamp, somewhere on the other side of a room, that isn't the main room light?
