If power supply swap has not fixed the issue - it is most likely system board.

However i would suggest to try few steps to check if that fixes the issue.

1.Try Bare Minimum configuration with only processor, hard drive and memory - disconnect the Optical drive.

2.Try removing the graphics card and check if that powers the unit up stable.

3.Try resetting cmos button.

If nothing helps please log a warranty call to replace system board in the unit.

if you are in the US and cannot locate a z820 board for a good price you may want to just buy a bare bones system from ebay,.... these are sold for about 400/600 depending on what is included

 

or as a last resort pm me,......... i have a board with a corupted LSI SAS controller (bad firmware update)

that can possibly be recovered or left as is (all other ports work)
