Hey everyone! I've been watching this video that explains how to determine the right power supply unit (PSU) for your GPU. It suggests looking up your GPU's minimum PSU requirement and then adding an extra 50-100W. I found out that the minimum PSU for my PNY RGB 5080 is 850W, which means I should aim for a 950W PSU. However, I'm puzzled because the GPU's TDP is 360W. Shouldn't the minimum PSU relate to the TDP? I'm trying to get some clarity here!

You definitely need to consider the entire system when choosing a PSU! Aside from the GPU, your CPU, RAM, and even cooling fans all draw power. It’s crucial to account for all these components. If you foresee any upgrades down the line, a power supply with some overhead capacity would be wise. Just do your research on the PSU brands, as some of them can get pretty hot!
A high-quality 850W PSU should be enough for the 5080 by itself. Just keep in mind, if you want to future-proof your setup or plan to upgrade later, getting a 1000W unit would give you that bit of extra breathing room. It's always nice to have that flexibility.
I get the confusion! Just remember, the PSU doesn't only power the GPU; it powers the entire system. Your CPU's power draw plays a big role too, and it can vary significantly. For example, high-end CPUs can draw a lot more power than others. Personally, I would recommend going for a 1200W PSU to be safe, especially if you have a powerful setup like a 5080 alongside something like a 14900K. Aim for 80+ Platinum or Titanium for better efficiency!
Totally agree with the others! If you're looking at a configuration that might pull near the max capacity of the PSU, it's best to get something that can handle more than just the GPU load. Go with something solid, like a 1000W or even 1200W if budget allows. You never know what extra bits you might add later!
