I just built a new system. System Specs: Case: NZXT ZERO 2 Crafted Series CS-NT-ZERO-2 Black CPU: AMD Phenom II X4 940 3.0GHz Black Edition Hard Drive: Western Digital Caviar GP 750GB 3.5" SATA Memory: OCZ Platinum Edition 8GB DDR2 800 (PC2 6400) MotherBoard: ASUS M4A79 Deluxe ATX AMD Motherboard Power Supply: Rosewill PSU RX750-D-B Video Card: BFG Tech GeForce GTX 260 OS: Windows 7 Beta However I was looking at Asus Probe Program and it shows that I am getting lots of voltage. +3.3V is coming in consistently at 3.55V +12V is coming in consistently at 12.64V So I downloaded some other software programs to see what it shows I am getting. SpeedFan, and HWMonitor. Speed Fan Shows this: +3.3V as 1.18V +12V as 6.87V HWMonitor Shows this: +3.3V as 1.19V +12V as 6.84V I am running windows 7 build 7077 so maybe thats why the two programs are showing those voltages... However I wanted to make sure, so I went into my mobo's bios and it shows: +3.3V at 3.56 +12V at 12.59 I am a little concerned about the high voltages especially since I just spent a lot on the new parts. What do you guys think?
ASUS Probe polls from the BIOS, and the BIOS is not realiable showing voltages. e.g. I call BS. If you really want to be sure, tap a couple of lines with a multimeter. But I'm 99% sure you have nothing to worry about
Ok I will get a multimeter to double check. Thanks! My second question if the psu is actually delivering those high of voltages. Could it damage my other components? And would you recommend rma or buying a new one?
ATX standard specifies a +-5% margin, 12.64v is over that, as is 3.55v. Seems like it would be just a faulty unit so I'd RMA if the readings are accurate, though Rosewill aren't one the best PSU brands out there.
If you're not having any issues with the system then the voltages are probably just fine...but you can check with a multimeter if you want...the BIOS and software methods can be way off and never right on. If your voltages are a little outside 5% spec then an RMA is called for yeah but it won't damage anything.
Well just checked it. And the results are in: 3.3v=3.55-3.7v:biggun: 12v=12.3-12.64v:biggun: So the min and the low are both above the standard I should rma the powersupply. Thanks for the help!
well that sucks...it's also unusual too but the quality control at the factory isn't so good off and on...Rosewill is a Newegg in house brand btw so RMA support should be good...the units did well here: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=60 voltages kinda high but not like that 3.3V rail of yours...yikes
well the only real thing I noticed is that my liquid cooling's fan keeps speeding up for no reason then slowing down then speeding up and slowing down. This is at idle and load. I wonder if its because the increased voltage that is causing it to speed up and slow down... Other then that The voltages remain pretty steady at: 3.3v at 3.55v 12v at 12.64v I did prime95 and the voltages stayed the same the motherboard temps rose to 39' C instead of the usual 30'C. Cpu temp was 50C' after an hour. Usually games and under load its 41C max, and 28C' idle. I think the 3.7 reading was only for 2 seconds, but it still was a little too high. My motherboard is set to warn me if it gets close to 10% too much power. Wonder if that means the board can handle the extra power... I sent in the Rma request haven' received anything back yet.
hmmm Well I got it replaced and the new unit was good... With 3.3vs and 11.9vs. So I put it in my system. Now the power is running at: 3.45vs 12.56vs And I smelt something burning out of the psu. So maybe My computer just wants more power? Not sure what to make of it...
hmm well that's with the multimeter right? are the batteries in it possibly old? the burning smell doesn't sound good...maybe it will go away...or maybe the RMA unit is toast
well its with the multimeter and the bios are basically giving the same readings. as for the smell i was told that psu's usually have a smell for a few days while you break them in. The multimeter is new, i bought it a few weeks ago around apirl 24. Right now I am just letting run to see how it goes. The voltages are lower then the other unit so it should be ok i think. 3.45 is better then 3.55 and 12.6 is still less then 12.64. And it seems my fans are no longer randomly speeding up and slowing down. so it should be good for now. Unless you have any other thoughts.
