Very Tiring Problem

So I dropped by microcenter yesterday, and picked up everything I needed for my new PC build. Dropped a good amount of money, only to come home, put it all together, and have it not work. (Actually first, I was dumb and forgot to hook up the 8 pin CPU Power cable) When I squared away the power cable, I still had no display when I hooked it up to the monitor. All the pretty lights came on, but no picture, and the mb gave me an A2 Q-code. Googled it, fixed it, blah blah blah. Got a signal on the monitor and installed windows. Then it came time to install the GPU and it drivers. This is where the most frustrating problem came up... So I keep everything plugged in i had plugged in. Turned off the computer, unplugged the AC cord, put in my GPU nice and snug, hooked up what i think are the right cables (my biggest suspicion is wrong cables or not enough power). But this time when i turned the computer on, nothing... no signal on the monitor. I still get the windows startup sound, but no picture. Ive tried it with and HDMI hooked into the GPU and the I/O in the back, and a VGA in the I/O... nothing. Took the card back out, and boom, picture on the monitor.

Nice build...what psu did you get(make and model and wattage)...make sure the 8 pin and 6 pin are the right cables, mine were labeled as pci, if they are the ones for the motherboard or anything else and vice versa, it wont work. So make sure the 8 pin plugged into your motherboard is also not the pcie cable too.

Its the Corsair RM850i. 850 Watts. It came with 3 cords labeled PCI-E. Its a weird one ive never seen before... it has one end with the 8 pin that goes to the PSU, and then the end the hooks up to the GPU is splits off into two 6+2 ends. both ends are labeled PCI-E. Ive tried using two cables to power it, and just one... nada on both

Do your fans turn on on the graphics card? Is there power to it that you can tell?

Maybe try a different pci e slot on the motherboard if you haven't already just to see if you get power.

Check in the bios to make sure your pcie lanes are configured right...just a longshot, most default settings should work fine right out of the box.

That motherboard is not an old one and shouldn't have any issues running a 980 ti or even having to make changes to the bios to get it to work.

EDIT: Also while you're in the bios make sure it didn't get switched over to integrated graphics as your main video output since you were using that to install windows first? When I built mine and installed windows, I installed it with the graphics card inserted and not the way you did, so mine automatically set it up that way but since you had it out, it might have changed a setting.
