Bought new gpu, pc won't start

[zen55]

Hi, its my first post so I don't know if I'm posting in the right place. I started building my pc a little over a month ago, I got all the parts except the gpu. This is my system:

I5 4690
CM hyper 212 evo
GB z97x gaming 5
8GB corsair ram
Seagate 2TB hdd
Corsair cx500 psu
Zalman r1 case

I put everything together and it's running windows 10 pro 64 bits. I have been using it and everything worked great, not a single problem.
I just bought the gpu, an msi gtx 970 gaming 4g and installed it. I have built a couple of pc's before and I think I'm doing everything correctly.

After I installed the gpu I plugged in the power cords and double checked everything, I turn on the pc and everything lights up as it should, I heard no beep and after a while it shut itself off and restarted, after a while (no beep again) it shut itself off again.

Uninstalled gpu and reinstalled it, this time it boots up and the gpu lights are on, but the fans are off, since it wasn't being used I thought it was normal and that the fans would start when I started playing games.
Then I found out that the pc didn't recognize the gpu so I couldn't install nvidia drivers.

After restarting the pc WITHOUT touching anything it went back to the old no beeping and restarting on its own thing. This time I checked all fans and all were working, even the gpu fans, which then stopped and the pc restarted again.

I think its my psu that can't handle the new gpu but before getting a new one I would like to know if it's possible the problem lies somewhere else.

P.S. I checked and in msi's site they recommend a minimum 500w psu to power this gpu, I even used a power calculator and the final result for the whole system was around 475w.

Thanks in advance for the help.

Personally I think your PSU should be adequate for a single 970 so I would suspect a faulty card or motherboard, do you have another card or access to another PC?

Thanks for the quick reply.

There are 2 more pc in my house, so if I try another card and it works I should return the one I bought and if i does not work then its another component right?

Also the no beeping issue is related to the psu or gpu?

If you try it in another PC and it works then I would try swapping over PSU's to see if the problem followed the PSU or the card.

Just remebered, for that to work the other computer must have a better psu right? I think that the other pc has the same psu as mine so it will probably have the same problem.

It might, it might not.

Just had another idea: if its the psu that can't supply enough power I can try to shut off my pc front fans to see if it works (I don't know how much power they need but they are both 14cm and one is led).
Crazy idea, if I use the other pc's psu to power only my graphics card. Would that work or does the psu need to supply power to other components to work properly?

That can work, you just have to figure out a way to trigger the other PSU run your GPU.
