Sorry if there’s a better community to put this in.
Basically title, I have a 9070xt and whenever I turn my PC on, the GPU turns on (RGB and fans), but I don’t get any post or display to either of my two monitors. I only know the rest of the PC is working because I can ssh in. According to fastfetch my GPU is “mesa llvmpipe”. After taking the 9070 out and putting my old 6700xt in, everything seemed to work fine.
I brought it to a PC shop just to see if everything still worked. The 9070 worked in their machine, and it also worked when they put it back into mine. I didn’t touch anything, brought it back home, and now it’s back to it’s previous behavior.
I already have a new psu on the way (550w made sense when I first put the system together) but I’m not actually sure it’s causing my current problem because it worked at the PC shop.
Any help or insight would be appreciated and I can update with more information if required
Plenty of folks do have their systems overbuilt - in fact, I see far more builds come through my shop with excessive power supplies rather than the opposite.
Power efficiency is a factor that varies based on model, rating, and load:
In this case, though, we’re talking about using a 550W power supply with a card that will readily use a little over 300W at load with occasional spikes that might reach as high as 400W. OP Probably has a fairly efficient CPU or maybe doesn’t have their card at 100%, but it is cutting things close and I’d expect this power supply to suffer excessive wear over time.
