Hipro HP-P3017F3 PSU has no voltage on the 3.3v rail and also shuts off when p7(4 pin floppy ) is connected The psu is from a Dell Inspiron 570 There's no green light for 3.3v on the power supply tester Should I bother trying to fix it Does it sound like a bad connection to the 3.3v rail or orange wire and would be an easy fix or might it be failed components
