I guess the question is rooted in the length of the PSU, most ATX PSUs are about 90 x 150 x 160 mm or smaller while that model is 85 x 150 x 200mm, so about 4cm longer than most.
If there aren't any other requirements of what it should offer (like being wide enough to fit the 158mm CPU cooler), have you tried looking on pages like newegg and filter for measurements?
