@mds1man 

First try an old cure:  Unplug the rear power cord, and use a medium setting on a hair dryer. Blow this temp into the fan housing for about 3 minutes.  Then re-attach power cord, and try the PSU.

Exact replacement   for the 180W PSU.    

 

As computers get more powerful, the base line for an standard ATX form has grown in minimum wattage.  A typical PSU without a PCIe GPU cable is now 300W +.  This 450W would meet future needs, even handling a GPU (graphic card) within the 175W range.       Compare you old PSU
