well if the PSU fits in and bolts ( well screws actually ) up that is a good sign. the things to then look for is that the PSU fit tight up against your case and the cut out in your case allows the PSU fan to operate without obstruction. You should also make sure you can plug your power cord in and operate any power switches. If not Yes you may have to mod the case to let all of the above happen. Just be careful not to cut out where you PSU screws up as you need to have 4 screws holding your PSU in your case
