I put together a new desktop about a month ago with the following specs:
i7 - 4790K
Sapphire R9 390
Seasonic 650W PSU
MSI z97 gaming 5 mobo

Things were working fine and I had multiple long gaming sessions until yesterday, I was gaming and computer shut off randomly and I wasn't able to power it back on - no fans, no LEDs on the mobo, nothing. I left everything connected to the motherboard but unplugged all power cables from the PSU except the board and was able to power fans and the board. By sequentially powering down, plugging in another component and testing power again, I got to the point where the CPU and hard/optical drives powered on and essentially I was able to get the computer on and running off of integrated graphics.

Then I plugged in the the graphics card (which had been seated in the pcie slot through all this testing) to the PSU and tried the power, once again no power to fans and no mobo LEDs. I'm pretty sure that this means I need to RMA my graphics card but I'm definitely not an expert and wanted another opinion.

Thanks in advance!
 
Solution
It looks indeed like a graphics card issue. If same issue with graphics card inserted in different PCIe slot, then I'd RMA the card.
