yes it has 2x6 pin, but i just connected one cause in the box there was just one cable. But its that necessary until my pc just detect the graphic card?

Have you checked the bios to make sure it is being recognized there?

Yes, i checked and it already was "PCI/PCI-E" as main. but no the bios doesnt say if the graphic card is recognized or not unforunately :/

if i plug the hdmi at television to test if it does smthg, it says "no signal"

R9 270X needs minimum 500W PSU that provides at least 24A on 12V+ rails. Yours is 400W with only 18A. If you want to run this card you need to swap out the power supply and it needs to have two 6-pin connectors connected.

And stop trying to make this card work on your rubbish PSU before it blows up in your face.

re-marked noname 350W PSU and angry monster from AMD - bad company...
try disconnect all HDD, DVD if present, coolers except on CPU if video still not started - buy normal PSU

I know power is not enough, but my question was why my pc doesnt detect it. Card needs more power till it can be recognized by pc?

How can PC detect it when it doesnt even get enough power to work, not to mention dont have one 6-pin connected at all, it's basicly dead card.

Okay, got it! Thanks!
So i will look for an economic power supply enough for running this card at least...
I have to search for smthg particular? It has to have 2x6 pin connectors?

550-600W with two 6+2 pin PCI-E connectors will do.
EVGA, Seasonic, XFX, be Quiet, Superflower, at least bronze certified.

Would have needed to swap out the PSU anyway if you wanted to run anything gaming worthy.
Your current PSU could not even run low power consumption card like GTX 750 Ti because even that takes more amps then your PSU provides.
You seem to have quite rubbish quality PSU because 18A means it can manage to produce only 216W of power, not 400W as it boasts. Common problem with cheap generic PSUs.
