Computer doesn’t power on when gpu is plugged in

samuelrodrigescortes · Dec 1, 2017

My computer is a gigibyte ga-z170x gaming 5
CPU g4400
Ram Corsair lpx 2100 oc 2400
Gpu r9 380x Asus strix
Psu evga 500b

It could be various things. May not be seated correctly, power supply connectors not making a proper connection, the video card itself could have gone bad, the pci-e slot on the motherboard could have gone bad, the power supply itself could be acting up.

I would first try cleaning the pci-e slot & the video card with 90% alcohol(the pins, not the entire card) & then making sure the card is installed/seated properly. Then make sure the PSU connections on the card are plugged in/secured properly.

If that doesn't work, then borrow/buy another video card(for testing) or possibly see if a local repair shop is willing to just test another video card

toshibitsu :

i have tested it on 2 motherboards and i tried a kentek 600w power supply my evga and my bfg 500 watt psu i think it might be a problem with amps does anyone know if these psu's can support this gpu

Candan · Dec 6, 2017

600w is more than enough for an R9 380X if working properly

samuelrodrigescortes · Dec 6, 2017

Candan :

yeah but the 600w only has 22 amps on the 12v rail

Candan · Dec 6, 2017

You do need 28 amps on the 12v+ rail for that card

samuelrodrigescortes · Dec 6, 2017

Candan :

yeah but shouldn't my evga 500b be able to power it has 12v+ at 40 amps but then i plug the gpu in the fans twitch once and then the power button becomes unresponsive and then i need to turn off the power supply and turn it back on for it to work again

Candan · Dec 6, 2017

Doesn't matter. Your GPU should only be drawing 28 amps anyway.

Your PSU should only be pushing 40amp on the 5v or more on the 3.3v rail.

More volts, less amps. More amps, less volts

Candan :

so what could the issue be?

Dark Lord of Tech · Dec 6, 2017

kentek 600w power supply my evga and my bfg 500 ...All three are very poor , the only one that is even close to decent is the 500B , other 2 are junk.

samuelrodrigescortes · Dec 6, 2017

thanks for responding but even with my evga only the fans twitch and nothing else happens

Power off and turn off PSU,
Unplug gpu,
Plug monitor cable into mb
Boot
Do you see display?

samuelrodrigescortes · Dec 6, 2017

vapour :

thanks for the response and yes

vapour · Dec 6, 2017

So when you plug in gpu, did you put monitor cable into gpu? What monitor and cable are you using?

samuelrodrigescortes · Dec 6, 2017

vapour :

i plugged in the monitor cable to the gpu earlier and the the mb and i'm using dvi-d

vapour · Dec 6, 2017

I will suggest a different cable.

samuelrodrigescortes · Dec 6, 2017

vapour :

the computer doesn't boot or turn on

bignastyid · Dec 8, 2017

Does the system work using the igpu and the 380x removed?

vapour · Dec 8, 2017

bignastyid :

his answer is yes, it works with IGPU.
