Just bought an MSI GTX 970 Gaming 4G to replace my old 460 (Ya, been a while). Plugged it into an MSI 990XA-GD55 motherboard and hooked it up to an Antec TruePower Trio TP3-650 power supply. I used the 6+2 PCIe connector in the 4 pin slot along with the 6 pin PCIe connector, get a B2 error. I used the 6 pin to 8 pin converter that comes with the video card, get a B2 error. Not sure what is going on here. Is the 970 compatible with the 990 motherboard or is the TP3-650 power supply the culprit here?
