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.

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?

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.

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.

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?

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?
