Buying a new graphics card

[JoonOh]

Hello i currently own a ibuypower i-series 301 and im planning on buying the gtx 1080. I've opened up my computer to look for the PSU but it wasn't there. Does anyone know if my computer can run the graphics card? I've tried asking their support which didn't help.

Hello i currently own a ibuypower i-series 301. I opened up my computer to look for the power supply unit but it wasn't there. I tried asking their support which didn't help. Does anyone know if my computer can use the gtx 1080 graphics card?

The power supply is the metal box inside the computer that the power cable plugs into. If your computer powers up when you push the power button then you have a power supply in there. If it doesn't then I would not recommend buying that videocard.

I mean my computer does have a power supply unit but it doesn't have a number on it. It is a asrock yellow metal box with no number. Is there any way to figure out my power supply? I have a graphics card but my fps is really bad so i was thinking of buying the gtx 1080 for my new one.
