Is a 800VA / 480w UPS (Uninterruptable Power Supply) enough for the PS5 ?

Hello,
Knowing that the PS5 is still pretty sensitive to sudden power drops (whilst turned on or in rest mode) I decided that I should buy a UPS. I found a good bargain for a brand new 800VA / 480w UPS and I was wondering if it is enough so that I can safely turn off the PS5 until the power is on again. I do not want to play games while the power is down nor do I want to connect anything else into the UPS -- it's just for the PS5. The PS5 will NOT be kept in rest mode.
I'm expecting the batteries to last a long time since power loss is very rare here (it happened once, for a few seconds, 8 months ago). Maybe I'm OCD but I'd rather be on the safe side since the PS5 has unfixed issues with sudden power loss (like storage failure). I'm afraid that it will break and the store in my country (Europe) will give my money back since there are no replacements due to lack of PS5 stock.
So what do you guys think? Is 800VA / 480w enough to safely turn off the PS5? Can I go lower than 480? Should I go higher?

You are right. I forgot to take into consideration the fact that I need the TV to be On on order to be able to power down the console. So this adds an extra ~80W to the power consumption.

@Zefan No, because the console will go in rest mode instead of shutting down if you press the physical power button. Also if you turn off the tv (or the power is cut to the tv) the console will go into rest mode.
