Voltages seem to be within parameters, 5V isn't shown on the program but you can check it from bios. So atleast voltage regulation seems to work fine from what can be told from your pictures. Did you have some problems with the unit or just worried due to the age? Quality units can last for a long time.
Edit. If you wan't to test it a bit have HWInfo running while putting some stress on the system to see if the voltages stay stable. 12V might drop a bit under load, but aslong as it stays within parameters it is not a problem. You can check the specifications from
wikipedia ATX page, scroll down almost half the page for the table.
