I'm in the process of finalizing my PC build and the local shop insists that I need a 1000W PSU along with a 2000VA UPS. They mentioned anything less would be 'risky' for my setup. My main question is whether 1000W is excessive for my Intel Ultra 265 and 5070 Ti. I've read that 750W or 850W could be sufficient. Also, I have a 1080p drawing tablet powered by the PC, which might influence power usage. What do you think?

A 750W PSU should handle your setup without any issues. A well-made power supply will be more than adequate for those components.
You could actually run that build on a 550W PSU and be just fine. Just make sure it's a reliable model; avoid those cheap units!
The 1000W is really just for noise control; higher-end PSUs often don't use fans until under really high loads. If sound is a concern, 850W seems like a sweet spot, but honestly, it's likely you're being upsold. For a 1000W PSU, a 2000VA UPS is more than needed—1500VA would usually be enough and save you some cash.
An 850W PSU is sufficient for now, but a 1000W could be useful for future upgrades, just in case you want to add more power-hungry components later.
Seriously, it feels like your local PC shop might be trying to take advantage! Based on what you're building, I'd say between 750W and 850W is ideal. The 1000W would be silent most of the time, but it seems unnecessarily high for your needs.
Exactly! The maximum load for your build probably won't hit 600W. An experienced tech should definitely know that.
Right! Just check for a modern one that has good build quality to ensure safety and longevity.
