I just got an R9 280x Sapphire Toxic so i just powered off my PC took out the old 7850 and installed a new one and connected 2 8 Pins (2+6 and 4+4) and now when i turn the power supply back on the motherboard green lamp is on but when press the power button nothing happens.

I have the xfx 550w bronze edition and its kinda new.

I installed the cables that came with the GPU now it powers up but i get this error:
Data in ec or ec flash might be corrupt.

My mobo is ASUS M5A97 and it is less than 1 year old and it was working fine until this morning.
