Sentinal low power warning....

post #1 of 16
Thread Starter 
Need alot of help.... I have been getting a Sentinel warning for low power. My temps. seem out wack too.. Speed fan - temp.1 34,temp.2 59d, HDo 30d, temp.1 37.... How do you properly check voltage? I see it said +12v was 11.8 ? Is that stable? My GPU is hooked up with a molex connector . There are no more cables I can use to give it its own. It is sharing the Hard drive cable. I have dusted and all wires seem fine,snug .
I did a Nvidia stability test and got the warning , I was also getting it gaming but not all the time. Any thoughts. I really don't know what more info. to give but can get it if needed. Thanks!!

Could it be your PSU is supplying VERY dirty power to the card ( is it dying or old)?
That could cause it

But how do you tell what kind of power its giving? It is a Cheapo PSU thats for sure. Any thoughts on the temp.2 of 59 deg.? Thats an idle temp. what is it measuring?

teh 59 is most likely the GPU core temp, its fine. 6600's should take in upwards of 78-80 before having issues.

The 11.8 seems a tad low but not unheard of. my PSU's +12v is at 12.23 right now.
*EDIT* if you have another 400w or above PSU lying around, try that one and see if it helps at all, Also my 6600gt did that when i negleted to properly plug it in (Left the plug only in about half way) You might also try switching the molex that its hooked to to another

One thing too is that these are idle measurments. I do not have another psu lying around . Should i try and load the system down and test then . is there a surfire way to tell if the psu is burnt or going to hell?

Your PSU is old, its not able to give you the stable power above 12v anymore. A very common problem for cheap PSU's.

ok.............how can I test a psu's stability to prove it to myself?
post #8 of 16
If the PSU is cheap, I'd replace it at the first sign of problems. My last build lasted 3 months, then EVERYTHING was fried when my faulty PSU finally gave up the ghost.

Well I got a crappy Dynex PSU from BestBuy and have a more power consuming rig than yours, and I don't have any stability problems. It might just be that your PSU is starting to break down.
