I have a 510 watt rated cyber power battery backup that is plugged into my pc
its an 8700k and 1080ti and it usually always stays below the rated limit at around 250 watts. sometimes during gaming it will beep saying its overloaded but not often and it goes away after a minute
my pc is idle most of the time when i lose power and it successfully powers the pc

my question is I plan on upgrading my 1080ti to ampere, i dont know which one yet but lets say i got a 3090 and I know these cards will have a massive power requirement (I have an 850w seasonic psu)

my question is at idle i assume it will be ok to plug into my ups but what about gaming when it will go over the 510w limit

so my question is, is my ups sufficient or would i need to upgrade to a bigger one?
