This power supply needs to go into a ATXm-ATX form factor desktop. Your PC is a small form factor. I am having problems seeing what your main power connect looks like. if it looks like the one in the picture on this answer then you have an option. If you are okay with a larger PC then you can find a PC(Purchase from here at Best Buy[look up "ATX case"], from a friend, or recycling center with permission.) that is one of the atx family(ATX is your best beat), remove all parts from that PC and place all the parts from your PC into that one. You will need to find a different CPU fan and get some Thermal compound to place on the CPU before fan install. The PSU will support gaming to an extent. You need to look at the recommended requirements on the games you want or have and see if all the other hard ware will support it. If the game need a gigabyte of Graphics processing and you have the standard 128MB plus system ram share you are going to have a bad experience as it is constantly having to swap graphics processing with CPU processing and so many frames are going to be skipped. It will look like a stop motion film. There are many youtube videos on these types of arrangements. You may need to find longer SATA cables for the transfer look for 2' I could not post this in the recommended items. You might could do with a cheaper fan but you may need the heat sink too(assuming yours is not a screw in type.)
I hope this helps!
