Asus GTX 980 Strix, no post or beep on MB

[coolbigbear]

Hi and straight away thanks for the help. I would consider myself a pretty techy guy but I am at a loss here.

I just bought a new Asus GTX 980 Strix. I'm getting a lot of trouble with it though. When it gets put in to my system the system doesn't post or display video (doesn't matter if power cables are connected). As soon as I take it out its fine.

PC Spec's:
CPU: AMD FX 6100
MB: M5A78L-M/USB 3.0
PSU: Coolermaster Thunder 500W
Storage: 1.5 TB WD HDD, 120GB Intel SSD

Some more info:
The system beeps when ever its turned on before a post message, with the 980 it doesn't. It also doesn't matter if the 980 is powered or not. If it's plugged in to the motherboard, no post or beep. I had an Asus HD6850 before and it worked just fine no problems. I can still put it back in and it works just fine system beeps, posts and then boots up windows

What I tried:
Put the card in my friends system the card worked fine so its not broken. I tried it in both the PCIE 3.0 and 2.0 slot since he has 1 of each on the motherboard. I swapped his power supply with my one and tried to boot the card in MY system still no post or video.

Friends PC Spec's:
CPU: i5 3570k
GPU: EVGA GTX 760
MB: Asus P8z77 v lx
PSU: Coolermaster 600W
Storage: 1TB WD HDD, 120GB Intel SSD

I put in my friends GFX in to MY PC to see if it would work. Absolutely no problems. The motherboard beeps and posts. I'm at a total loss. My motherboard has a PCIE 2.0 slot but 3.0 is backwards compatible so it should be working fine. My PSU is good enough to run the card so that doesn't seem to be the problem. Could there be something in BIOS that I need to change? (I reset all settings and had a look through but I don't understand most of the BIOS jargon) Could CPU be screwing something up?

Thanks again for all the help

I'd say the PSU, many CM '500' watt PSU s only have about 300+ on the 12 volt rail and believe this is a dual 12v rail - want a good 500 with at least 30 AMPs on the 12 volt rail and 450 + on the 12

Edit: looked it up, this only has 408 on the 12 volt rails - 24 AMPS on one and only 21 AMPs on the second, would replace it

That was my first thought too. I got 45 AMPS on dual rails. That's why I checked it in my friends PC. He's got a 600W Coolermaster with a single 12V rail (48AMPS), it worked just fine. So I took his PSU out and put it into my pc to see if my PSU was the problem. With his 12V rail 48AMPS PSU the system still only powered up but gave no beeps and did not post.

same happened to me when i got my 970gtx - updated my bios to last version and problem solved .. update yours

Right an update.
I benched the system and I discovered that the GFX works as long as pressure it applied during boot to it. That is I had to push the GFX in to the motherboard right after pressing the power button. As soon as the system beeped to signify that everything is ok I could release the pressure.
This is pretty weird. The system works just fine after doing the above things. Even played some BF4 on Ultra on it. Worst part is I have to do it every time I boot up the system. BTW my BIOS is up to date.

Bad PCIE slot it is then.
Thanks for the help guys, really appreciate it
