I have a PC that recently needed a graphics card upgrade. We installed a 3070 Ti. Before, it had a 1050 with a 500W power supply. But after swapping the graphics card without changing the PSU, the PC keeps restarting. So I believe the problem must be the power supply. What I find strange is that 500W isn’t that bad, right? How can I know what wattage I need to buy? 650W units are quite expensive in my city, but is that probably what I’ll have to get anyway? Which brand would you recommend?
