I received 2 MSI Lightning R9-290x cards for a gift to replace my single 7970 MSI Lightning card. The new R9-290x no longer uses the cable adapter to do cross over and they now use the PCIe bus for cross over. I powered up the system with the first card and the system came up. Then I added the second card, now the system just "turn off then on" for one second repeatedly. I tried a second psu and it did the same thing.
I placed the original video card in and the error continues. I pulled out all memory, video cards and disconnected all SATA drives. The error continues with the "turn on/turn off". When the system turns on for the 1 second, power is provided briefly to the external USB drives.
I checked pcpartspicker and added the power requirements. I thought the RM850 was enough to power my system. The only solution I believe is my board (ugh) but does anybody have an opinion?
My question is, is this a board and/or PSU (not enough power)?
My systems spec are as follows:
Case: Cooler Master HAF 932 Full Tower
Memory: 32 Gb of Corsair Vengence
Board: Gigabyte GA-X79-UP4 Max memory 64 Gb
Processor: i7-3820

Optical Drive: Asus Bluray DVD writer
Operating System: Windows 7 Ultimate SP1 64 bit
USB connectivity: 6 external Western Digital drives, mouse, keyboard, HOTAS petals/rudder and joystick setup
Monitor: 48" Vizio LED TV

Radeon R9-290X-33A and a 600W psu minimum. So with that you really think like you said the RM850 would work. I would unplug the power pull the battery and clear the cmos for 15 mins. Put everything back then see if it will boot with one card in.

I have just tried your technique by pulling the CMOS battery, leaving the system off for 15 minutes and short the CMOS to reset. Same problem, system just turn off and on continuously.
(1) The board is toast and need to be replaced?
(2) This board was shorted out because it did not support (2) board/bus level cross over for new R9-290 cards. Does this board support the new crossover technique over the PCIe bus? Also, I will go get a 1000w to support the cards.
Someone please respond about this board before I purchase another to get the system back up.
