Forgot to mention, prior to losing all video output, I was receiving an error 43 I believe it was, on the 770, when checking the card on device manager.

It would usually crash about halfway thru gaming. I attempted to reinstall windows and that's when I lost all display completely, so I'm unable to complete the OS install, the card isnt being recognized at all on boot up.

So I have been running a GTX 770 (was unaware of the 600W min for the card, was given to me) with Ryzen 5 2600, 16GB 3200 in an MSI gaming carbon pro on my corsair cx550. It started with some game crashes, screen flickering and freezing. Then I'd lose all video but audio continued to play. Today after freezing HDMI was gone completely but DVI still worked to get to the splat screen, but then after a flicker all video cuts off, but PC continues to run. Now at first I thought it was a fault in the PCIe slot which in turn choked the GPU out, so I already made plans to replace both mobo and graphics card. It was until i was informed of the 770's 600W requirement that I realized I could need a new power supply. Would the machine still turn on and function normally, aside from loss of video, if the PSU was failing? I'm probably still going to get a new mobo and GPU, I'm looking at a B450 and a GTX 1660 super, but how likely is it that I'll need a new power supply as well. Thank you, First time poster.
