Title: HELP! Can't connect more then 2 GPU's Post by: Scofield on August 13, 2016, 04:18:45 PM Im using a Asrock P81 Pro BTC mobo, along with some MSI r9 390 gaming 8gb cards.
When I plug 1 or 2 cards in, it works fine. But when I add a 3rd card, I don't get any singal to my monitor. Sometimes it boots, I can tell from the led's on my keyboard. It seems like a power issue to me, but I'm not sure why. I've tried many diffrent GPU's, risers and PCI slots.. I use 1x Corsair 650w to power the mobo and 1 GPU. I use another 1000w PSU to power the other two cards. |
