PS Voltage look bad?

[tomblits]

Heres what my speedfan 4.42 shows

Vcore1: 1.12V    min: 1.02  max: 1.33  mean: 1.24
Vcore2: 1.60V    no variance
+3.3V:  3.38V    min: 3.34  max: 3.38  mean: 3.36
+5V:    5.03V    min: 5.00  max: 5.03  mean: 5.01
+12V:   12.54V   min: 12.48 max: 12.61 mean: 12.55
-12V:   -4.46V   min: -7.59 max: -3.97 mean: -4.60
-5V:    4.05V    no variance
+5V:    3.60V    no variance
Vbat:   3.23V    no variance

As you can see you -12V raid is fluctuating and my -5V raid is positive? heres a picture of the chart


My rig consists of a Gigabyte motherboard, Nvidia GTS 250 video card, Phenom II x3, 6 HDD, 1 SSD, 1 CDRom, 4 Tower Fans, 1 CPU Fan, PCI Lan Card, G15 USB Keyboard, Razer Imperator USB Mouse. I probably put more then necessary because I don't know what is and don't want to short you on information.

My PSU is OCZ ModXStream Pro 500W Modular High Performance Power Supply

That is a good example of how good those programs are,(as well as the sensor), as that power supply has no -5volt, like most new ones.(it dose say no variance though).

Until you check the voltages with a multi-meter, you have no way of knowing exactly what the voltages are.


I can't explain the -12v being all over the place, and low.
I think they still use it, or it would be gone like the -5v, or maybe not.
Is there a problem.

The +3.3, +5, and +12volt all look within tolerances, but I'm sure they would be different with a meter, mine always are.

Bottom line, you cant use that to monitor your voltages...
Your using questionable software readings of questionable hardware monitors...
Why are you worried about your voltages?
are you having issues?
are you having stability issues?
If not dont worry about it...
You have a good brand of PSU and it looks to be more than enough for your setup...
End of issue..

Thanks for the timely and well worded answers. My tech friends all use over compensating PSU's 750-1000W and I'm not well educated on them, thanks for sharing some of your knowledge with me. I'll look up the signs and symptoms of a failing PSU so I can spot it if it ever were to become a issue.

Just read the PSU sticky...
