on the slightest chance it will fit. but it will fuck up your usb connectors as it will hit the cover, the best solution for you is to buy a new case with cable-management design that hides your psu, or let the wire pass , or make your own psu cover. its just a damned metal sheet folded 90 degrees. just cut the area where the wire will pass,
--edit--
Plastic acrylic is more safe than metal
