Sorry to be the bearer of bad news but the PSU is junk and should not be used anywhere near any new card, see my canned text below;
Please note that there is one thing that is possibly worse than using a known poor quality brand of PSU and that is using one that is unheard of, for brands of PSU to trust and brands to avoid please refer to the two attached links here and here
PSU database here
Before purchasing a new PSU it is advisable that you measure the dimensions of the present PSU and ensure that the new PSU has the correct power connections for the MB, HDDs, optical drives, FDDs or add on cards such as a video card if one is fitted.
The present PSU is of such poor quality that it does not even have one let alone the two supplemental 6 pin PCI-E connectors that a GTX 980 requires, see PSU product description here, you will also note the absence of any claimed amp ratings
From your picture we cannot see how much room is available inside your case, you need to measure it yourself and then let us know, you do have a case blank next to the present card so a dual card of some description will fit if you remove the blank first.
