I'm trying to figure out how much power my PC build uses. Here are the components: Ryzen 9 9950X3D, Tryx Panorama ARGB, Gigabyte X870E Aorus Pro X3D ATX, Corsair Dominator 64GB 6000 CL30, Samsung 990 Pro 4 TB NVME SSD, Asus Astral OC 5090, be Quiet! Light Base 900 DX ATX Full Tower, and Sea Sonic Prime TX-1600 ATX 3.1 1600 W 80+ Titanium. PC Part Picker says it would use 902 watts, but that doesn't include my monitor, an Alienware AW3225QF 32 inch 4K QD OLED 240hz. I've heard that PC Part Picker's estimates might not be the most accurate, and that's why I'm considering getting a UPS. I was thinking if 1000 watts would suffice, but what do you all think?

Keep in mind that the monitor runs off its own power adapter, so it doesn’t affect your PSU directly. For your setup, while 1000W might work with a good PSU, I'd still suggest a 1200W just to err on the side of caution.
To be on the safe side, I’d recommend getting a 1200W power supply. 1000W seems a bit too close for comfort, especially considering that the 5090 can draw around 575W at full load.
PC Part Picker gives you a good estimate for your PSU specs, but it won't consider the monitor's power. If you're just hooking up your PC and monitor to the UPS, 1000W might suffice. However, having a 1200W UPS would be safer to handle surges.
