I'm having crashing problems with new-to-me 2080 Ti It works great in most games because I play with VSYNC on at 60 Hz. But when trying out nVidia's Star Wars raytrace demo, it crashes. This is with my 6 years old Seasonic S12G-550 550w PSU. After some thinking, and make sure the crash is reproduceable, I tested by adding a second PSU: common ground, a no-GPU computer with a really old Corsair Hx620 giving one 8-pin power. My 550w give the rest. No more crash. The screenshot shows 8-pin #1 12v, provided by other computer. PCIe voltage and 8-pin #2 from my 550w at 11.6v. I used to only buy Seasonic built, but I thought this good quality 550w should be enough for 2080 Ti With overclocking in mind (when I get back in Silverstone FT02, one of the best air cooling case), 130% power for 2080 Ti would be 325w. What PSU is good nowadays? I think I need 2 cables going to the GPU, 1 cable is just not enough. At least 80+ Gold for efficiency please. Don't mind modular or not. TLDR: 6 years old Seasonic S12G-550 voltage drops when 2080ti tries to pull loads of amps. I need a new PSU, I'd like 80+ Gold or better, don't care about modular. Considering 130% overclocking power limit, I'll need a PSU to power the 325w card. 2 cables to GPU. What brand is good? What would you recommend?
