psu readings

[lockmac]

I am just wondering whether these are acceptable volatage readings, as my computer freezes whenever I turn on my UV light.

On the +12v, i am getting 11.126
On the +5v, i am getting 5.16
On the +3.3v, i am getting 3.312
on the VCore, i am getting 1.552

Could someone please help me
thanks

I don't know what CPU you have so don't know about the Vcore. Your 12v rail is waaaaaay too low. Mine never goes below 12.1.

I have an A8V Motherboard and an 3500+ Newcastle and a SilenX powersupply. I am also having problems everytime i turn on my UV light with the switch on the UV bracket, the computer freezes which im thinking maybe I haev a dodgy powersupply.

What kind of PSU do you have? Aristo is right, that 12v line should be no lower than 11.76 to be within most makers +/- 2% tolerance. There are some who have 11.6 on the 12 and still have stable systems but 11.1 is freaking low and veeeeery bad.

My advice, get a new PSU ASAP. On the cheaper but decent end look at Aspires, Thermaltakes, Enlights on the more expensive but better end look at Enermax, Antec, or Fortron.

One thing you can try to do to be sure is unplug everything but necesary parts (CPU, RAM, Main HDD, CPU fan, thats IT). Unplug all optical drives, any extra hdd, all fans except for your CPU fan and see what your voltages look like. If they are much higher then your PSU is weak and you need a new one. If there is no change then your PSU is "teh suck" and you need a new one. Either way, you probably need a new PSU.

Ok. My BIOS is telling me that the 12v is fluctuating from 11.76 to 11.72. The program that asus boards comes with is called Asus Probe and that is constantly telling me that the 12v is 11.126 or 11.187. Which one should I trust? Is there another program out there that is reliable?

Also as I said in previous post, I have a UV light and connect it to the power supply. It isnt even in the computer case and when I flick the switch on the PCI bracket it comes with, which isnt even in the computer, the computer just plain freezes. The light will work but freeze the computer.

I am so hoping it is not a dodgy psu though, I cable sleeved all the cables and replaced the molex connectors, and they may possible not accept it as a return

Take the BIOS readings over the software. Having said that the only truly accurate method is a mulitmeter.

If you have a multimeter use that. My bios was reporting my 12v line at 11.5 but when I checked it with the multimeter it was at 12 so the bios can be inaccurate

For someone who has never taken a PSU measurement, how would one go about reading the 12v voltage with a multimeter? Thanks

I know this is an old post, but I was using Fuse Talk's new and "improved" search function in an effort to avoid a repost about running a light at 5V and this is the first thing that came up. :roll:

Ahem....

You take the positive probe of the multimeter and stick it in a yellow wire of an extra drive molex for 12V or red wire for 5V and the black lead of the multimeter in any black wire (common ground.)

Now back to the search (I don't want to post something and see "repost" in my thread....)
