The NVIDIA RTX 3080 continues to be hard to find nearly a year after its launch, mainly due to the ongoing global chip shortage. If you're set on buying one of these high-performance GPUs, be sure to have a look at our guide on where to buy RTX 30-series graphics cards for more information.

While NVIDIA recommends a 750W PSU for the RTX 3080, it tested a system with a 10th Gen Intel Core i9-10900K processor (CPU).

If your PSU is showing its age, it's never a bad idea to prepare your PC for the RTX 3080 upgrade to prevent failures and damage to other parts. Yes, the new NVIDIA RTX 30-series GPUs have a 12-pin connector, but they will come with an adapter for your older connectors.
