Hey folks! I'm currently running a 7800 X3D with a 7900GRE, but I'm planning to upgrade to a 5090. Right now, I have a 1000W PSU. Do you think I should upgrade to a 1250W instead?

A 1000W PSU is likely adequate for your setup since the 7800X3D is power limited. Just make sure your specific PSU model is reliable. What kind do you have?
Agreed, 1000W should be fine for your needs.
I've got an i9 14900k paired with a 5090 on a 1000W PSU, and it works just fine for me.
Yeah, as mentioned, a 1000W unit is usually enough. If you plan to undervolt and overclock the 5090, you could save about 200W from your power consumption!
That's wild! I didn't realize the savings could be that high. Does undervolting affect performance much?
I have a Corsair RM1000x, and it's 80 Plus Gold rated.
