I recently purchased a used Sapphire Vapor-X R9 280x video card from Ebay. I plugged it into my system, and it seemed to work fine with my 500W power supply. But when I tried doing anything graphics intensive, the system would freeze immediately.
I decided that it was freezing because my power supply couldn't supply enough power, so I bought a 850W power supply. Unfortunately, I got nothing but scrambles with the new power supply. So I ordered a replacement. (EVGA 850W) With the 3rd PSU, I don't get any signal at all.
Here is where it gets weird: the gpu works fine in my friends system, which has a 1000W PSU and an AMD processor. If I put his gpu in my system with my power supply, it works great (the only difference is 2x 6-pin instead of 2x 8-pin) If I put my GPU in his system with my power supply, it doesn't get any signal to the display.
So basically, I'm not sure what the problem is. I think it is for sure either my GPU or PSU. It seems like the card works if paired with a certain set of hardware, but it fails to work on my system for some reason. I'm at a loss of what to try replacing next! I guess I could order a new card, but I'm not sure if the seller with take the current one back, since I don't know for sure if it actually is broken.
Here is my build:
EVGA 850 G3
i7-7700k
Asrock Z270m Pro4M
16 Gb Ram
Sapphire Vapor-X R9-280x 3Gb DDR5 (Requires 2x 8-pin or 2x 6+2-pin connectors)
2x SSDs
PS: My system also works fine with a 1050 ti installed.
