szoze Posted January 9, 2011 Share Posted January 9, 2011 Hi all I am new to this forum and want to salute all of you current members. I bought my Corsair VX550W a couple of weeks ago and I am quite happy with it. It runs cool and is very quiet. My concern is that the 12 rail voltage, as it is repported in Everest software and in MSI Dual Core Center, varies between 12.23 and 12.32 Volts in idle. Actually it jumps between these two values every other second or so. I feel that something can be wrong with my PSU's voltage regulation. All other voltages seem to be fine and stable. What do you think? Is there a reason to worry? Cheers SZ Link to comment Share on other sites More sharing options...
Synthohol Posted January 9, 2011 Share Posted January 9, 2011 software monitoring can be unreliable. best to check with a real meter. other than that there are regulators on the motherboard that should make that irrelevant. correct me if im wrong but i think the CPU gets its voltage from the 3.3 or 5v rail not the 12v anyway.* *self correction, AMD uses the 5v rail and intel uses the 12. either way i wouldnt worry about it since the CPU will only use less than 2v and will be regulated.

Thanks for your answer. I accidentally wrote CPU instead of PSU ::pirate:: The interesting thing is that this variation is shown even when my system is at full load.

szoze Posted January 9, 2011 Author Share Posted January 9, 2011 Even in the BIOS I can see that the 12V Voltage fluctuates (alternates?) between 12.232 and 12.32 Volts. Do you think this is normal even if we know that there is inaccuracy in the motherboard sensors etc. Cheers SZ Link to comment Share on other sites More sharing options...
Wired Posted January 9, 2011 Share Posted January 9, 2011 Personally I wouldn't worry much as it's well below the max ATX variance of 12.6v. Link to comment Share on other sites More sharing options...
merk666 Posted January 14, 2011 Share Posted January 14, 2011 Do you think this is normal even if we know that there is inaccuracy in the motherboard sensors etc. looks like fluctuation if 7th bit in a value of voltage. step looks like 1/128 of the value. real value is somewhere between 12.232 and 12.32 volts. so bit fluctuates.

Thank you! Let's hope that's the problem :-) Link to comment Share on other sites More sharing options...
