Critical Voltages. HELP!

[alikum]

Please have a look at the screenshot and comment. Help is very much appreciated.

Specs:

AMD Phenom II x4 955
MSI MA790GX-G65
Kingston KVR1333 2x2GB
Radeon HD4850
Xigmatek Modular 750W
Windows Vista x64

Notice that when I run HWMonitor, the +5V is not even within the specified +-5% range that all manufacturers should meet. Also, take a look at the extremely low +12V. This is a newly built system. I would like to know if this is alright or shall I RMA it?

HW Monitor often reads the voltages from the wrong points, dont use it to check the voltages, use a multimeter to do that. If your system were that far out of spec it wouldnt even turn on, so dont worry about it.

xigamatic's oem is hec

Well, hunter315, I am dead worried actually. I spent a lot on this build. I kinda regret not purchasing the Corsair 750W (more expensive) instead. Unfortunately I do not have a multimeter nor am I allowed to do so. I do not want to run risk blowing a fuse up.

@obsidian86
Is hec good? The only good brands that I know of are Corsair, Antec and Silverstone. Of course, seasonic too.

Should I bring it back? Or is it like what hunter said, it's normal?

hec is iffy these days but not yet bottom of the barrel

 

[hunter315]

It reads my 12V as 3.3V and my 3.3V as my 5V , check your voltages in bios they should be more accurate. If you check with different programs you will get different numbers.

In some cases, not this one though

That's exactly the model that I am having.
Okay, just checked BIOS. Here are the readings:

CPU Vcore @ 1.392V
3.3V @ 3.312V
5V @ 5.061V
12V @ 12.056V

Does this mean that I can safely assume that HWMonitor is giving me crap readings? Cheers, guys.

 

[obsidian86]

hmm thought most were hec's

On a side note, since HWMonitor is not reading voltages correctly, can I trust it to read the temps? How much is the variation?

 

[jsc]

Your BIOS is accurately reporting the voltages. Tolerance is +/- 5%.

@jsc
Yeah, that's what I read from documents too. Which is why it scared the bloody sh*t out of me when I looked at HWMonitor's readings. HWMonitor is showing temp average at 50C for all cores, using stock HSF running at 5k+ RPM. Is this normal?
