Depends entirely on where in the world you are, but here in Canada I can buy an Ecoflow Delta 3 with a 1kwh battery and an 1800w inverter for like 750CAD. Your average off the shelf UPS here costs 300CAD and is only good for 900w, not quite enough for a higher end gaming PC running at full tilt (and it'll only be good for a few minutes and have no other function). A UPS that can match the Ecoflow would cost significantly more while being capable of less
Admittedly cheaper than I thought, actually just bought the ecoflow river 2 pro for 399 for unrelated reasons but that has >30ms switchover . The delta is 599 here so not too much more
A 900w ups here goes for around 200, you certainly don't get the same runtime but these would support graceful shutdowns.

A power bank that supports ~700 watts and has <10ms cutover time is going to pretty pricey.
