can i put a 500 watt in mine

I'm new to the whole gaming thing so in theory if I get a 790 dell optiplex I can get a 400-500 w power supply and a gtx 970 and then I can game?

Does anyone knows how much psu the pc is running on I can't seem to figure it out.

can i use an evga 400w power supply on it?

Is it possible to upgrade the psu of the sff with a 300w psu???

hey man, was curious. if i were to take and upgrade my power supply to say a 400w from the dell stock one for this same layout/model of Optiplex 790 SFF what power supply would you recommend? i cant seem to find one that looks like out of the box will work with this
