New PC - New Problem, maybe psu

[Blinded]

Hi there,

I've assembled the follow items:

I7 7700k
asrock z270 mITX ac
2x 8g 3000 MHz Corsair
M.2 960 Evo Samsung
2.5" 1 tb hard drive
Evga 760 sc 2G
Node 202 with integra PSU 450w

My problem is that sometimes the pc doesnt start with the gpu and starts with onboard. Somehow i manage to start with gpu and tried to start the game PlayerUnknown and then the screen went black with no signal, but the pc was runnig cuz i was hearing the start menu sound.

I think its the psu power. it is too weak, and was hopping to get some answers from someone on the fórum.

Thanks

Is your video cable connected to GPU? So game is starting, screen is black but you can hear the sound. What will happen next? Can u exit it with alt-f4 or alt+ctr+del?
Does it happen in every game? Have you overclocked your GPU?

Hi, thanks for you reply.

I didnt overclocked my gpu, early before assembly the whole project i've change the termal paste from the gpu.
I didnt try to exit with alt f4 (forgot that) remember to do crlt alt delete but didnt do cuz i have not display.
Just tried in that game, dont have anything more installed.
I will try another thing, just put the GPU without the pcie riser that came with node 202 case and try to start the pc and the game again.

I think i need to replace the 450w psu to a 600w.

Been searching in some sites, and give me this: https://outervision.com/b/LDKcEa
