12V goes as high as 14.1 with 2 HHD's connected.

[Montek]

I have ***** no name 350W PSU with only 10A on +12V line though i have simple internet pc, that uses AMD Sempron 3400+ AM2, build in video and one hdd and 1gig ram, nothing more, i believe 10A is fine for that, and voletadge was fine ~12v on +12v line when i last checked, though now i had to connect temporary second HDD (SATA) and voletadge is goes as high as 14.1V on +12v line, is it safe to leave it like this for few day's or it can damage something?

Are you reading the voltages with software ?
If you are you may want to check them with a voltmeter to make sure the software is accurate.

14 volts is over spec, limit is 13.2 volts.
Your pc might be ok with that, but I wouldn't be comfortable using it.

Like Modelworks said, is this software reading or a DMM reading?

I would suggest you replace that PSU if it truely is doing that. It is bound to kill something.

I heard that software reading of temperature is precise, isn't it same for voltage?

About voltmeter, i got multimeter, though i don't know how what settings should i set to check voltage. What i got looks like this one image can you tell me what settings should i set and where exactly i should take readings?

Link is busted, just gives me this little image "we strongly endorse wiredco.com"

No the software reading isn't precise on voltage (I've had it tell me my 12V was at 9V before, no way the PC would even run at that voltage) and it really tends to be not precise for temps either tbh. Just gives a rough estimate more than anything (coretemp seems to be the most accurate I've found).

DC 20V setting. Measure between any black and yellow wires. AIM for 11.4 to 12.6v +/- another 0.2v or so considering the questionable accuracy of your DMM.

Black & orange = 3.3v
Black & red = 5v
Black & yellow = 12v
The other stuff's not really relevant.

I read review that is showing temperatures are very precise and (if i remember correctly) voltages to.
Heres working link though its not one i have but its very similar image.

NeoPTLD there is 3 holes for electrodes on DMM should i use 2 lowest holes (and just for information is black diode goes in COM hole)?


Edit: okay i measured yellow and black and it reports 12.15v when software reports 13.8v.
What are chances that my DMM is wrong? How i make sure its not?

Can i cause any problems/damage if i connect for example to yellow and red with my DMM?

Btw its kind of cool, what settings should i use to measure wall socket, (our has ~220v).

It doesn't sound like you really know what you're doing too well, so don't use the top hole unless you're looking to blow up stuff.

Even a cheap DMM like that should be within a percent for DC voltage, 3-4% for AC.

$300 DMMs are usually good to 0.05% DC and 0.75% AC.

Can i cause any problems/damage if i connect for example to yellow and red with my DMM?

No. You'll just get the difference of the two with respect to ground. red and yellow gives approximately 7v.

~V 750.
Good rule to remember. If you're not sure of the voltage, always start at the highest, then work your way down and don't turn the dial with the voltage applied, EVER.

It shows ~230 what means 200V AC setting on DMM is it maximum allowed or something e.g. if i plut at 200v ac setting into 230vac line what happens?

BTW what color electrode comes for COM (com means ground?) hole on DVV?

 

[Zepper]

Only the spec on the -12V line has 10% tolerance any more. The +12V has +/-0.6V (5%) just like all the others now. Check the PSU design guide on formfactors.org.

It'll either pop the fuse or go out of range.

COM is common, the return line basically. The black wire goes to it.
