Hi Folks,

I recently made a new NAS server based on a TYAN s7002 and 2 Xeons E5504 processor. The PSU I use is a Supermicro PWS-0047.

The motherboard have 2 8 Pins connector for the CPU. As I have only one, I use the 4 PIN one with a converter (here are pics of it). Everything work fine, I made some load tests and no problem at all.

BUT I recently use hardware monitor and get a very strange results on the +-12V... you can see it is around 7V. It is definitively not normal, but I wonder you opinions about it.

Is it a problem with the software? I do not get any problem of instability, so I do not know what to do... Any helps or explanation are welcome :)

cheers,

Sergio

It's software. No software in the world can ever read PSU voltages correct. So don't worry about it.
 
If the voltage really was 7V, the computer will not be functioning. If you want to know what the voltage really is, use a multimeter. Otherwise, just forget about it. If you aren't experiencing any problems with the PC, there is nothing to worry about.
 
Thanks a lot!

I just went to the BIOS and check what was the voltage reported... and everything is fine ;) The 12V is not at 7V. So I put too much trust in the software results!

ah...well, they are more accurate for my well being but I will test them with a multimeter :)
I will keep the results posted :)

thanks,

Sergio
 
We really need a sticky that says no voltage number is correct unless you use a real multimeter.
 
Yes, and the multimeter results will also completely incorrect unless you use a analog digital super-weasel 900 RSRJ-X.

No; a budget multimeter won't provide a perfect reading, but most cheap ones should still be able to manage at least 1-2% accuracy with these kinds of voltages. Software and BIOS readings often produce values that are much less accurate.
