Help/Support Custom PC Graphics Card confusion

[Zigzagzul 307 8 9.0.2]

So I didn't really want to start by building a PC So I bought one for 250$ It has a nice Case and everything. The thing is that It was an APU so he thought that there was no need to put a GPU, which is fine. Now I am a bit confused, Since he has an APU there is a PCIE cable going into the APU slot, Then the PSU only has one PCIE cable to plugin into the GPU which is in the currently in the APU to power it So will I need to get an entirely new PSU to get 2 PCIe cable or is another way to install a GPU, and If I need a new PSU can you recommend me one with at least 2 PCIE cable. http://www.evga.com/Products/Product.aspx?pn=100-B1-0450-K1
