It would have been simpler to replace the fan.
Meanwhile, clone power supplies typically need to be 30% larger
wattage to be equivalent to the wattage typically standard in non-clone
computers. Furthermore, power supplies selling on price and watts
typically are missing functions deemed essential even in power supplies
30 years ago. IOW what that possibility is becomes irrelevant.
Meanwhile, be more concerned with solving a problem without
speculation. Two minutes with a 3.5 digit multimeter answers your
questions AND provides numbers so that others can post a useful reply.
Get a meter to learn what is wrong, immediately, and before replacing
anything. Solve a problem the first time. Procedures to take such
measurements were detailed previously in

Will this solve a USB port problem? No way to tell. However all
types of strange electrical, plumbing, and hardware problems occur when
a house's foundation fails. Power supply is the foundation of a
computer. Check a foundation before moving on to other suspects.
