Do i need to change my power supply unit before upgrading my GPU (GTX750--> GTX980 or 1080)

Hello everyone, 

So my graphic card is getting really old and am thinking of upgrading it (still not sure if i want the GTX 980 or 1080 cause i usually play on PS4) 

Anyway, 

I just want to know if i need to upgrade my Power Supply as well ? 

If any expert here can tell me what is the Power Supply power that my model got shipped with then i can just look out if it s gonna be enough or not. 

thank you

Hi,

Power wise, definitely you need more power from GTX 750 to GTX 980 or GTX 1080

750: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-750/specifications

980: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-980/specifications

1080: https://www.nvidia.com/en-us/geforce/products/10series/geforce-gtx-1080/

750 consumes 55W - 980 consumes 165W and 1080 consumes 180W.

Regards.

Thank you, i was just talking with a retailer (the one am going to buy the GPU from) and he said that i need a new PC case in order to install the new GPU, is that true ? 

thanks

Hi,

Tat might be true because the old card requires single slot but new card need 2 slots and you need room for new PSU too.
