Voltage questions

post #1 of 6
Thread Starter 
Hi all, I was just curious about Voltages on my Computer, this seemed to be an appropriate place for it, However im not volt modding, just wanted to know if my voltages are running too low and what not, currently the 3.3 is running @ 3.18 the 5.0 running @ 4.87 and 12.0 running @ 11.78 according to my asus pc probe 2. My question is is that too low, i dont know really know anything about voltages and i feel like they should be running atleast what its supposed to be running at? So 3.3 should be @ 3.3? and not running @ 3.18-3.20 (as of right now) and so on and so forth? My current psu is an Antec tru power Trio 650 and i am running sli (7900gs's), dual core processor (805) and im also overclocking, any advice, help, ect. would be much appreciated

Software doesn't always give the correct voltages. Get yourself a good multimeter and follow this guide.

Okay, thanks ill have to give it shot, but also was wondering in the event i do find that the voltages are running around what i posted after manually checking the voltages with the multimeter, would those numbers be too low? Or is that the maxium voltage that rail can do or should it always run at the rated? I.E the 3.3v should run 3.3, and if those numbers are too low, what can i do without having to buy another psu? The psu i have i read alot good things about, and which is why i purchased it. Thanks again for the help

Well generally, they should be within 3-5% of the rated voltage.

oh okay cool, so assuming that those reading are correct, if i divide 3.3 by lets say 5% which is 0.165 and add that to the current value i should be able to see if its in range? Again Thanks a bunch for the help

5% of 3.3 = 3.165-3.495 The closer to the rated number the better.
