PSU question

[bassboy_pete]

Hey guys,

I just installed MBM 5 to view different information on my motherboard and my PSU. I noticed this information about my PSU though:

Core 0: 1.68V
Core 1: 1.23V
+3.3V: 3.10V
+5.00V: 4.58V
+12.00V: 12.01V
-12.00V: -6.42V
-5.00V: 0.00V

Whats going on with these numbers? Are they ok or what?

Thanks

What kind of PSU do you have? That -12 looks very low...

i think MBM5 is reading wrong
if u were actually running at those rails, then ur Computer wouldnt be at all stable

Power supply is Antec TruePower 480. Forgot to include in first Post. My computer seems to be pretty stable. No problems at all.

The -12v line isn't used that much, if at all (thanks to the PSU info thread (a must read) for that info) So even if it was low, it wouldn't effect much.

You could always test w/ a multimeter

 

[bassboy_pete]

thats a good idea, thanks. I think it just isn't reading it right anyway.

the -12V isn't used (generally) in modern ATX systems.

I've had PSUs from multiple manufacturers (from generic crap to PC Power & Cooling) read a "low" -12.

Ignore it, it doesn't matter.

I think it was only used in ISA slots.

Those were my server readings with that prog, go into ure bios and go to the hardware menu and check the volts there cuz mine were WAAAAY off

MBM and BIOS use the same information, so that is *not* a better solution. The only way to know what your voltages are is by using a multimeter.

...a plug for the thread stickyed at the top of the forum on PSU's. It's a good one.....

I know how it reads it but the program sometimes messes it up. The bios almost never does

it could be a bad sensor on the mobo. Maybe the -12v line sensor isn't well calibrated...

If your system is stable, I wouldn't worry about it. As stated before, your rig is probably completely ignoring that line anyway.
