When choosing a PSU for an RTX 5080, what factors beyond wattage, like efficiency and modularity, are essential? Given discussions about 750W minimums for prior generation GPUs like the RTX 3080, what's the optimal wattage for the 5080? How do 80+ efficiency ratings (Gold, Platinum, Titanium) impact long-term power savings and system stability? Does modularity significantly affect cable management and airflow? Considering discussions on "next-gen power" for RTX 50XX GPUs, are there specific PSU brands or models renowned for reliability and high-end GPU compatibility, like those mentioned in discussions of "A and B tier" PSUs for the RTX 4090? What features should be prioritized, and why?

For an RTX 5080, aim for a minimum 850W PSU, considering "next-gen power" needs. Besides wattage, prioritize an 80+ Gold rating or higher for better efficiency and lower operating costs . Modularity definitely helps with cable management and airflow. Look into reputable brands known for high-end GPU compatibility, similar to "A and B tier" lists for the 4090. A quality PSU ensures stable power delivery, crucial for the 5080's performance.

Saw this thread and had to chime in because honestly, relying on just the 80+ Gold sticker isnt enough anymore. I learned that the hard way with a previous build where my unit kept shutting down during power spikes... it was super frustrating and honestly a letdown after spending so much on the GPU. For a card like the 5080, you really want to look for ATX 3.0 or 3.1 compliance specifically. Those old tier lists are okay, but they dont always account for the massive transient spikes we are seeing with these newer cards. I would actually push for 1000W just to have that extra headroom. I ended up swapping to a Corsair RM1000e 1000W 80+ Gold ATX 3.0 recently and it handles high-end loads way better than my old 850W ever did. If you want something that feels a bit more premium, the Seasonic FOCUS GX-1000 1000W 80+ Gold ATX 3.0 is a total beast. Seasonic usually has better ripple control in my experience. It kinda sucks that we have to spend this much on power now, but it beats having your PC crash mid-game. Let me know if you need help picking out the specific cables tho, those new 12VHPWR connectors can be a bit finicky if you arent careful.
