I've got a 750W power supply, and I'm thinking about upgrading my setup to include an AMD 9800X3D CPU and an RTX 5080 GPU. I'm curious if my current PSU will be sufficient or if I should consider upgrading to an 850W or even a 1000W unit for better safety and performance. What do you all think?

Ideally, I'd recommend at least an 850W PSU, especially looking to the future. Because the efficiency difference isn't huge in pricing, it's usually smart to go a bit overboard and grab a 1000W if your budget allows!
In my experience, a 750W PSU will be adequate. Your overall power draw should stay below 600W with that setup, but if you want to be extra cautious, an undervolt on your GPU might also help reduce power consumption.
While a 750W PSU can handle the load, transient spikes are a concern. If you're worried about stability during high loads, stepping up to an 850W for peace of mind is a smart move.
Yeah, I've read that quality PSUs are rated to handle spikes really well, but it doesn't hurt to play it safe.
Yes, a 750W should generally be enough, especially if it's a high-quality unit. Just keep in mind that it's a good idea to plan for future upgrades, so if you're going to keep your system for a while, consider investing in something a bit bigger next time!
Totally agree! A PSU is a long-term investment, and having a bit of extra headroom is always safer.
I've got a similar setup and found that 750W is okay, but it's pretty tight. If you're serious about gaming or heavy tasks, an 850W would give you better headroom and avoid any potential shutdowns.
Exactly! Better to have extra wattage than to risk system crashes during gameplay.
Good point! Undervolting can really help with efficiency.
