here are my rails at idle and my rails at load, i have a 510 deluxe. and i up'd the voltages a bit. I was wondering if these are too high or its ok. I havn't measured these with a multimeter, since i don't have one.

thanks

As long as you aren't dipping under 3.3, 5 and 12 I wouldnt worry about it. Even then some PSUs will be slightly under but ok.

I wouldn't necessarily trust MBM-5 or any software to accurately measure your rails, however; I only say that because you said you adjusted them. With a PCPower 510 their using much more accurate equipment to set those rails at the factory before that unit is shipped. Without a multi-meter it's difficult to tell how far you "really" adjusted them. They look perfect to me and mine are about the same on my Turbo Cool, but I wouldn't adjustn them without a multuimeter even if they were low, because PCPower&Cooling redefines how current is measured, they are the standard by which all others are measured.

What do the voltages look like in the BIOS? I'd be more inclined to trust the BIOS rahter then a program reading the same source because one is a "secondary" software Windows-GUI, the other is no nonsense BIOS data reading from the same circuit.

they look about the same in the bios, but the reason why i adjusted them is because i was under the impression that a little overvolt can increase overclock and stablity. i mean if it is a risky thing, and you guys think its not wise to keep it this high, i'll lower it back down a bit

thanks

Personally I don't trust MB monitors. They often are not reading correctly. But if rails are stable and are within say 3% range it should be ok.

BIOS uses the same sensores as MBM5 L3D.

i agree with the fact, that they aren't that accurate, but in general do overvolting of rails result in greater stability and overclock??

Sometimes - overvolting increases heat which can cause instability, but mostly it's beneficial.
I'd get or borrow a multimeter if you're worried about your lines.

I just measured my rails and they are different what MB says. 12V rail is 11.96 at stress test without overclock and ~11.80V when increased voltage and overclock. It really seems Antec is not that good PSU cause of low 12V rail.

looks like it is on par with my HEC 425watt...but still ok provided u r not running high cfm fans and couple of hard disk..the word ok is too poor to described it..the correct word will be its good actually cos my specs is running overclocked 24/7 and as far as i am concerned there is yet any trouble i had all these years....most of my friends use cheap 420w enlight truepower and its damn good for its price of less than 40 usd...12.10 and 3.35 at full load----readings from multimeter of cos....
