+3.3V on my PSU is going nuts...

DriveEuro · Dec 22, 2002, 09:27 PM

My 3 month old generic PSU has always worked like a charm until today..... The 3.3V rail keeps running like at 3.5 and peeking at 3.6 a lot....So I have damn ASUS PC Probe popping up every few minutes. The PSU fan is clean and all the insides are clean.... It's always run fine...but now it's being gay.... Now is it ok that the 10% threshold is being broken about every 3-5 minutes? Can I change the 10% threshold warning to 15% and just disregard it? Am I to worry? I know the weather here has dropped about 10 degrees farenheit the last couple days.... Outside temp is 15-25F and the house is a little cold to........but I doubt that would have little to do with the PSU... Should I disregard the warnings?

Its very hard to say, though if this was spontaneous, and happened very suddenly with a definite point where you can say, "this started happening then", and wasn't gradual, I would guess that it is equipment failure, such as a non-essential capacitor blowing inside the PSU and it's throwing your 3.3 voltage off. If it was gradual, it might be any combination of things including equipment deterioration. My recommendation would be to order a nice, new, BRAND NAME PSU, as the power supply is one of the biggest factors in overclocking - if the voltage drops too low for the amount fo power your silicon is drawing, bam! crash. If its drawing a hell of a lot of power because of overclocking, and a little unstable, even the slightest amount of voltage fluctuation can be deadly and cause an extremely unstable system. Personally, I would recommend the 500 watt variants of the Antec and the Enermax PSU's, I have the Enermax 431 and it works like a charm, though I'm starting to stress it's limits with 5 large 7200rpm hard drives and an original stepping AXP at 1.8...
