12V rail at 12.67 while idle - Page 3

post #21 of 42
And $10 vs all the hassle of sending your PSU back to NCIX, being without your rig for a week or more...
Sounds like a decent $10 to avoid all that trouble.

Never mind I just checked, at least $30...
1. I spend $30, a little of my time, and it's resolved, but that multimeter will probably never be used again.
2. I send it to NCIX, they test it and possibly replace it, takes up to a week.
3. I spend $30, a little of my time, turns out bad, then I just wasted $30 anyways, and have to send it to NCIX and wait anyways (longest time).

Software is most likely misreading. Without testing with a multimeter, you have no reason to waste your time and money taking it to a shop. It's worked fine for a year, what makes you so concerned now?

I understand your mind is made up; still worthwhile to pick up a multimeter at some point. I use mine all the time, to check PSU health, to see if batteries are charged, to monitor mains voltage during windstorms, to check that capacitors are good, for science experiments... Just a very useful tool, everyone should have one.

No money will be lost by simply taking it to NCIX, though yes time.
I'm not that concerned, because yes it's been working fine all this time, but better safe than sorry eh?

Yes it would be quite the useful tool, but I honestly doubt I'd end up doing any of those things for a while.

Perhaps I should wait till tomorrow when NCIX office opens again and I should get a reply as to how long it'll take. Since I live not too far from it, maybe I could also arrange to avoid any shipping, and just pick it up from there myself.

To be fair, this thread inspired me to pick up a DMM, I was at fry's and I found one for $9.99 (AND AD-5526), it's a cheapo lil gadget but for what you need it for it's fine. It took me about 1 minute to find a guide on checking PSUs with DMM, and literally about 15 seconds to do it. I had been worried about my own PSU as well since software had been giving me crazy numbers:

HWMonitor Report
+3.3V -- 3.25V
+5V -- 2.94V
+12V -- 4.05V

and when I popped the leads into my molex with the system under full load (folding@home smp + kombustor) the DMM read:
on 12V rail 12.15V
on 5V rail 5.08V

Now I know that my PSU is working pretty much ok, ~98% within spec with a tiny bit of overvolting. My mind is at ease. And I didn't even have to turn my computer off to do it.

NCIX replaced my BFG 550W for a Corsair CMPSU-600CX without any questions, or delays whatsoever, and they didn't even test it.

Now looking at HWMonitor, I'm seeing the 12V Rail capping at 12.67 (it averaged 12.67, capped at 12.74 before).
Maybe the BFG wasn't bad after all?

EDIT: Never mind, the voltages are the EXACT same and fluctuate the EXACT same way.
I think... my sensors, are screwed up.

EDIT2: Never mind again, it's not fluctuating AS much as the BFG, probably cause it is actually a better PSU.
And now I see, the +3.3V is almost exactly sitting on 3.3V. Definitely is better.

Your motherboard sensors are crap. Like we've been telling you.

ALL motherboard voltage sensors are crap.
