Graphics Cards

Hello, I have this graphics card, but with a 400-watt power supply.
 When I open a more demanding program, the computer just shuts down with the power light on. 
The graphics card is connected with a 6-pin connector to an 8-pin input. Its 6+8 pin card..
I wonder if it will solve the problem if replace the power supply with 8pin connector because this one have only 6pin.

also it comes with i5-4460s on 65w usage

idle wattage of gpu is 32w which is normal for Sapphire Nitro+

You want a 500W psu with pcie 8 & 6 pin cable/connectors.

8pin is enough for like 150W but im upgrading Z230 with 18pin port and my psu that i bought has 24pin so i ordered 24 to 18pin adapter

PSU 500 watt minimum.  Recommend a 650W - 850W if your budget will allow.  Corsair has a holiday special: https://www.corsair.com/us/en/c/psu/atx-power-supply

Yes, the RX 580 REQUIRES an 8 pin plug and draws 185 watts

I bought psu but it has 24 pin and motherboard has 18pin port..so i ordered 24 to 18pin adapter

PSU has only one 6+2pin for gpu so 75w from pcie and 150w from 8 pin equals 225w

Still don't know what motherboard you are using.  That I am aware of ALL motherboards will have at least one 6 or 8 pin CPU power plug, AMD or Intel.  Make certain you have that connected, the cable I see in the image provided is an 8 pin.  I see that it is not a modular PSU and you only have 1 PCIE cable.

I think OP should contact Sapphire Tech support, see what they have to say about only using 1 pcie power connection on his 8 + 6 model.
