Hi

just wondering what does -5V from PSU (Epox USDM) reading tell you

mine is rather high at
-5v @ -5.350 ~ 5.4

mind you other readings are all fine:
+5V @ 4.919 (max deviation)
+12V @ 12.464 (max dev.)

this readings are CPU FULL LOAD (Prime Torture test)
1700xp TbredB @ 2100Mhz (200Mhz FSB) 1.8V

PSU is Enermax 365 (350W) -5v....1A (looks fairly unimportant I know )
+5V...32A
+12V...26A
+3.3V...32A
