Considering buying a 5080 model with concerns about power delivery.
Considering buying a 5080 model with concerns about power delivery.
Hey everyone,
I’m setting up with these components right now:
CPU – Ryzen 7 7800X3D
RAM – 32GB
GPU – RTX 3080 (10GB)
Motherboard – MSI MAG X670E TOMAHAWK WIFI
Power supply – Corsair RM850e (2022 model)
I’m thinking about upgrading to the RTX 5080 and want to make sure my current PSU can handle it. NVIDIA says a minimum of 850W is needed, and a recommended 1000W. Since my RM850e isn’t ATX 3.0 compatible, I plan to use a Corsair adapter with two PCIe ports for 12VHPWR (rated for 600W).
I’m worried about whether the adapter would work under load and if each PCIe cable can safely deliver 300W. I also need to check if the total power demand of the 5080 plus the rest of my system would exceed what this PSU can provide.
Any advice would be greatly appreciated!
Which RTX 5080 models are you considering?

Your main worry is the RTX 3080's reputation for significant power spikes, which could harm its lifespan over about three years (from wear and tear). You should be okay with the adapter Corsair to connect with your PSU or opt for the one that comes with your GPU.
Thank you for your reply!
I’m considering the Gigabyte Aorus Elite Master 5080 but might look at other models if I find a better offer. For the sudden load spikes, I usually don’t push my 3080 to full capacity often since I rarely play the odd triple A game. Given this, would it still make sense to buy a new PSU to go with the 5080?
Your PSU has sufficient wattage to meet the GPU's requirements according to Nvidia's guidelines, which is good. The main issue is ensuring all connections are secure to prevent melting due to high power draw. Even with this, there might still be some worry, so be mindful of that.
