Depends on the wattage of your kids pc. Imma assume they are on average 500 to 600watt, unless they using top of the line rtx 30s, that would increase it to 700watts.
Upcoming vid cards, rtx 40s gonna require up to 1000w power supply.
Eeeeeh, it's probably not too bad. The TDP of a 5700 XT is apparently 225 watts, so that's the absolute maximum it's drawing at max load, but Roblox and Fortnite shouldn't actually make it run that hot. Other than that, you probably use about up to 100W for the CPU (and again, much less in practice), and everything else like drives, mobo, fans etc. is going to be just a few dozen watts on top of that and the PSU is running at less than half load at the max. And that's only when you game, for youtube, browser etc. the whole machine probably draws about 50-80W.
GPU makers use intentionally overblown "required PSU power" in their technical charts because some people skimp on the PSU and buy some cheap piece of shit that says 1000 W but can barely do a half of that before it catches fire, and they don't want people complaining to their tech support saying they plugged their card into a machine with a "400W" (actually 200W) PSU and it keeps shutting down at high load. Well, that and AMD/nVidia have no way of knowing what else is in your machine.
Buy a plug power meter if you want to be sure, they're not expensive and they'll tell you exactly what draws how much as long as it's plugged into a wall socket and not hardwired.
