AHHH 10.3v off the 12v line?!

[Towlieee]

Ok I have a generic psu, Logisys fully acrylic 500w...

It maintains decent voltages though, all voltages being perfect except for a constant 11.77-11.86 on the 12v line...

I just took the psu apart, and cut the connectors on the led's in the fans, and took the 8 leds out of the 2 fans...

Now I boot up, and im at 10.3 volts! It drops to 10.17 when I kick my cold cathodes on!!!

What gives? All I did was remove led's, if anything, it should help the voltage out!?

Will this hurt my computer to run it like this? It seems stable, im at 100% load folding..


edit: ok I paused folding, and it jumped to 11.3-11.4... Still way short of its usual 11.7!

Ugh, been folding 3 days straight at 11.77volts, and now its way way low

what are you using to measure your voltage?

software that came with my motherboard

However I had a multimeter a couple days ago, and the software **** near matches the multimeter... except I gave my friend back his multimeter and i'l have to wait tell at least tommorow to get it again.

Its crazy, i even had ELEVEN 80mm fans on my 12v line when I first got the comp, but I moved 5 of them to the 5v line, and my 6 radiator fans on a external power supply....

edit: that software being "smartguardian"

This is how you do it & yes running out of spec PS's is a known cause of death.

I know how to check voltages..


But I mean, even if the software is off, why would it go from 11.77 just before I remove leds, to 10.3 after I remove the leds?

I dont think the software just became really inaccurate during the led removal..


maybe?

I have no idea.

make sure that none of the wires you cut are shorting out...
thats about all i can think that could cause this...

[Towlieee]

uh..

I got another friend with a analog multimeter.. One that a needle goes back n forth..

I set it to the 10 DCV setting, and it shows my 5v line as 4v, and the 3.3 at like 2.5...

But it also shows a 1.5v aa battery BRAND NEW at 1v.....


How am I supposed to set this thing to check voltages? Theres no way its showing me the right voltage

It's better to use digital multimeters to measure voltages accurately

Analog multimeters are better to watch trends of changes in voltage, because digital ones have some lag

[Scrufdog]

when you want accurate readings always use a digital meter. They self calibrate each time you turn them on and are easier to read. Analog meters are nice for quick, non-essential measurements, as they can become inaccurate even straight out of the box. This is because if you drop it from as little as 1 foot and it lands the right way, the needle will be off.

well..

im broke tell I get a job, I have one computer..

Guess i'l just run it with a 10v 12v line =\

[Towlieee]

holy crap im a IDIOT...

I spent the time to route all my wires and crap right.. but I didn't even plug in the 4 prong connector to my mobo!

I was pulling my psu back out so I could check the fans to make sure nothigns crossed.. Then I unplugged all the wires but the 4 pin one, and relized it was already unplugged....


So much for the warning all over my motherboard "NEVER OPERATE WITHOUT PLUGGING IN THE 4 PRONG ATX CONNECTOR, FAILURE TO DO SO WILL RUIN YOUR MOTHERBOARD!" lol

good thing im sending this mobo back in for a rma soon ><

If you continue to run your computer at a significant undervolt you should expect damage to other components. I seriously doubt that disconnecting the LEDs would cause a change in output voltages. It is more likely that something else was unknowingly damaged. If you are committed to messing with the PSU further may I suggest that you unplug both fans from the internal 2-pin connectors. You could then temporarily replace them with a couple of case fans and retest the voltages. Of course the best idea would be to immediately remove the power supply and toss it into the trash.

^Your post just appeared. I hope it was just the 4-pin mobo connection.

Ya, Its reading fine now, 11.77v on the mobosenors

Im glad nothings hurt.. Good thing I didn't use it long without that thing connected
