PSU problem (maybe)

Hi guys,

I just picked up a OCZ Modstream 450W psuand im wondering about voltages on my system. They don't change much underload, so here they are (Using MBM 5):

+3.3 = 4.41 V
+5.00= 4.08V
+12.00= 11.55V (constantly over 12.00V, but not by much, according to Everest)
-12.00= -3.64 (this one tend to be random, as i wa typing this it went to -10.46 then 0.80)
-5.00= 0.00V

Are there any problems here? I used to get random restarts with my old PSU, but not anymore, plus my CPU temp has gone down to 21 C, according to MBM (P4 3.0 GHz Northwood)

no

Voltage readings are always wrong, the only good they serve is to see if there are major idle/load differences.

You won't know for sure unless you measure with a DMM (digital multiMeter). Unloaded rails on switching power supplies tend to float - nothing uses the negative voltage rails any more, so... Make sure you use the latest version of the hardware monitoring software that your mobo maker supplies (MBM5 is no longer being maintained - time to give it up) and also the latest BIOS update available to be sure you are getting the most accurate readings - but they will never be as accurate as with a DMM.
. If those voltages are verified with a DMM (but I doubt they will be), then it's RMA time as many are well out of spec. In fact, if they were really that bad, I'd expect you to be having significant stability problems.
