Internal 300W (100V-240V)

Form factor: Internal ATX

Total wattage: 300W

This is from the Dell website. I am going to buy a new graphics card but I am going to need a new PSU too. Just want to make sure I get the right power supply. I know almost nothing about computers, so a specific link would be great.

Also while I am here.......I am likely going to get an R9 270(x). My CPU is an AMD a8-5500 APU. Would I see any bottleneck with the R9 270x? If so I may get something a bit cheaper. This is simply for gaming....no streaming/editing/recording.
