  1. Hello guys I just bought a r9 390 and installed to my pc but I saw that my psu has 1 x 8-pin AUX Power Connector and 1 x 6-pin AUX Power Connector and also my psu is 550 watt. r9 390 needs 2 x 8-pin AUX Power Connector and I put one of the 8 pin into 8 pin and other 6 pin from my psu to other 8 pin. When I opened my pc, I heard windows open sound etc but it was all black screen from the start, even didnt show up bios screen. then I closed it. I really hope it didnt but do you think my r9 390 gpu got burned or something thats why it didnt show anything or it s just not enough energy and nothing happened to my gpu I hope : / ?

    A 550w power supply is not even close to enough for that card youll need a 750w minimum also the reason it wont work is because of you using a 6 pin and not a 8 pin. this is not a good idea... ever.

    Sincerely a very concerned citizen
