According to MBM5:
Core 0 average 2.29
+3.3 average is 1.60
+5.0 average is 5.05
+12.00 average is 10.82
-12.00 is 0
-5.00 is 0

I'm using a Antec Truepower 380

I'm not sure what these readings mean, but someone told me to check my voltages due to some problems i'm experiencing. sometimes, my computer won't power on whatsoever when I push the power button. I have to unplug the power cord from the back of PSU and replug it, and then press power button again for it to work. Happens completely randomly and not all the time.
Otherwise it's completely solid once it's on.

My motherboard is Epox 9NDA3J, which is not on the supported list of MBM5, so I chose some random Epox MB, i think EP8. Would that matter? Are these voltages ok? Any help appreciated.

According to Speedfan:
vcore 1.39
+12 is 5.72 volts (Seems to be way off from MBM5)
+3.3 is 1.6 volts

This is my 2nd PSU because I had the same problem with my first PSU, which was a brand new Antec 350 smartpower 2.0. I don't know if i just have bad luck purchasing these things, or something else besides the psu.

I'm also running AMD 64 3000, 1 gig value corsair, seagate drive, nvidia graphics and sblive.

Anyone have any ideas? Any help appreciated.

well sensors are wrong alot of times. you could be underpowered but you would expect major stability problems if you are under-volted.

although it's a pain, best thing to do is check the PSU rails with a multimeter (Google)

If everything seems to be working OK then don't worry bout it too much. Are your temps decent? (way to see if the amperage is stable too)

PSU FAQ

What motherboard are you using? those reading sound off by a large margin. Your board may not be supported since mbm has not and will not have a new revision. The guy who made it just got to the point that manufacturers did not want to give him the info needed to make it work and trying to find out what sensor were what on all the mobos out there was not feasable.

i'm using a epox 9NDA3J motherboard. Can this cause the problem I'm experiencing? It's strange how I have to unplug and replug the power cord for my computer to start up. Once it's on though, it's rock solid

Let me say this again.......


PSU FAQ

PSU may be part of having to unplug to restart problem but that board is not supported by mbm. You should be able to play with the sensors available to make it work. Try checking your psu with a multimeter to check your 12v,5vand 3.3v lines. My brother has that board and he has not experienced that problem.I think he just uses the software that came on the mobo cd to check his voltages and temps. Maybe a standoff missing or hitting something causing a short??

I have the big brother of that mobo - dont use mbm5. I use speedfan and it detects my temps fine, but voltages are gonna need to be tested by MM(as a comparison my 12v comes up at around 6.5volts in speedfam). The only monitored voltages are: Vcore, vagp, chipset, 5v, vdimm, battery, and 5vsb, and the most accurate way to monito those is with the USDM utility that comes on the driver cd. The 12v and 3.3v cannot be software monitored - which isnt a big deal because voltage readings are almost always off by a fair amount - more so then temp monitoring.

Grab a simple 10 dollar DMM and test from the molex connectors.

Today, I just received a new antec PSU replacement at my local store (Fry's) and installed the PSU. I'm getting the exact same readouts on MBM5 and speedfan to no surprise. I'm pretty sure it will work fine for first week and it will start to develop the startup problem.

I just installed the Epox diagnostic program (USDM) and it should list the 12v readings correct? There is no 12v reading, it just lists it as None - 0. I looked at the manual for it and the example, and it shows where the 12v readings should be. But once I run it, there's no reading, it's just grayed out and shows, "None." Is that what you mean Puck that it can't be monitored by the program? Also, I checked to see if there are any shorts, but can't seem to find any.

Am I suppose to use all the standoffs for the motherboard? I only used I think 7 out of 9 to avoid possible shorting.

I checked the faqs, but it doesn't really tell me why I'm having this sort of problem. I guess I should get a meter thing then, but that would be crazy if I get 3 bad PSU's in a row. I'm pretty sure the voltages are good because once the computer is on, it is very solid, never crashes and plays all my games very well.

Thanks for all the help, I'm beginning to understand more about this stuff. But being on a 3rd PSU, if this problem happens again, it's probably something else, not the PSU which I initially thought. You guys think it's safe to say that the motherboard has a problem? I'm beginning to think it is.
