Antec TruePower New 650 output voltage

post #1 of 4
Thread Starter 
Hi everyone, I am new here. I just got my new Antec TruePower New 650 today. After put it into the system, the output voltage I read from the sensor a little bit too high (although it's still in the ATX spec range).
listed below(at idle):
3.3V rail: 3.424V
5V rail: 5.208V
12V rail: 12.096V

I am specially concerned about 3.3V rail since I read this thread (http://www.overclock.net/power-suppl...-voltages.html)
from Phaedrus2129.

I was expecting a better output voltage range for PSU like this one. I previously had a extremegear PSU when I purchased my PC from cyberpower PC. But even this extremegear PSU gives me a better output voltage range than the Antec.

Any ideas on Why? Apologize for my grammar

First of all, welcome to OCN!

It sounds like you're using software to read out the voltages. This is not a very reliable source, as many motherboards use cheap sensors or have botched calibrations. The only way to truly know how your PSU is behaving is to use a voltmeter or physical PSU tester. Your 3.3V reading is definitely suspect, but again you shouldn't trust software readouts.

Your voltages should fall within these ranges: http://pcsupport.about.com/od/inside...-tolerance.htm

Software voltage monitoring is worthless (BIOS counts as software). If you want an accurate reading use a digital multimeter. If you don't have one you can buy them for $4-$20.

Thanks for the replies............ I just feel lazy to take the PC apart :-p But I think I will do it this weekend. Is the software ever give you the correct data??
