Are these too many devices to be running in one outlet?

I have two outlets (each with two plugs) in a bedroom of my house. I'm going to be grounding them and replacing them with outlets with 3-prong plugs. One caveat is that I have an AC that needs to be in a plug by itself, otherwise if I have a surge protector in the same outlet (different plug obv), I can't be running too many more devices when the AC is running.

Anyhow, so I have 6 devices (PS3, PS4, XBox One, a Wii U, a Samsung Tv, and a Vizio Soundbar) in the surge protector that's currently going into the outlet where the AC will be.

I was thinking about moving those 6 devices into a 12 outlet surge protector on the opposite wall, with my computer (300W-400W computer, nothing fancy), my router and modem plugged into it.

Is it safe to have 9+ devices in one surge protector plugged into one outlet? I won't be running all of the devices at once, but it's not uncommon for me to have a game console, my computer, my router, my modem, my tv, and my soundbar on all at once - and I don't know if that's too much power for one U.S. outlet?

That's more than I'd be comfortable with, with that many of them being major electronics. At the very least I'd try to keep the TV and consoles shut off when the PC is on.

The only way to figure it out for sure, though, would be to check your circuit breakers and figure out how much the circuits that run to that room can handle (bearing in mind that some houses have more than one room, or parts of more than one room, that are served by the same circuit; and also that ceiling and wall lamps may also be on the same circuit as a wall outlet,) then look up the manufacturer documentation for each device to find out how much power it draws, and do the math. Or you could pick up something like a Kill A Watt meter and measure their power...

Or you could pick up something like a Kill A Watt meter and measure their power consumption directly.

A 15-amp breaker has a rating of 1800w before it trips, and a 20-amp breaker, 2400w; but you want to try to keep them below 80% of their rated load if at all possible. So that brings it down to 1440w for a 15-amp breaker and 1920w for a 20-amp breaker.
