I just recently bought a used Sapphire RX 580 Nitro+ and so far, I have had nothing but trouble with it. The card looks to be in great condition, and I have contacted the seller, and they assured me nothing was wrong with the card, and they have a great feedback rating on ebay. After installation, I didn't receive a signal to my monitor. I tried several HDMI cables, 3 different monitors, reseated the card several times, and nothing. It was getting late, so I called it a night.
The next morning, miraculously, the monitor picked up a signal on my first try. I installed all the drivers the card needed, and then restarted the PC. Upon reboot, I was met with the dreaded 'No Signal' alert on my monitor. For the past 3 weeks, I have only been able to get a signal on my monitor around 5 times. Whenever I put the PC to sleep, or restart, the problem recurs, and usually takes around 3 or so hours of turning of and on until the monitor picks up a signal again.
Today, I removed the card all together, and hooked up my HDMI to my motherboard. Straight away, my monitor picked up a signal. I have rebooted my PC a few times just to make sure it wasn't first time lucky, and sure enough, I received a signal each and every time.
So, I am led to believe that I either have a dodgey GPU, or the PSU can't seem to supply enough power to the card. I have a Corsair CX550M PSU, which previously powered a GTX 1050TI with ease. I have read several posts on different forums stating that you shouldn't need anything more than a 500 watt PSU to power a system with a RX 580 GPU.
Any help would be greatly appreciated! I will list my specs below.
