my new corsair ax1600i power supply has been running about a week and is at 3.216 v  

on 3.3 v rail should i be concerned ?


12v is a perfect 12.000 it never moves that i expected from this  new type of power supply it better not

5v is 4.920

at idle and under load
 

 

it even said that on a power supply tester

 

the same thing happened on my last power supply twice after RMA  and it started causing issues with the pci express cards so i went with the big boy quality ax1600i another brand entirely.. not again.

 

is it because i have been lowering the cpu voltages with vcore offset?

ATX12V standard allows 5% variation in 3.3V rail voltage, so +3.135 V to +3.465 V. 3.216V is fine.

 

Not related to Vcore, that is step down from the 12V rail.

The motherboard voltage sensors are useless. If you want random numbers, you could also try random.org. The AX1600i also has voltage readings available through Corsair iCue, and those should be somewhat useful. Try those instead.

Such a small difference would not hurt anything.

AX1600i is a digital PSU that can read the output voltages. Install Corsair Link for that.

i installed corsair link on the laptop because it is easier to just plug the power supply into the laptop than use a usb header it passes it self test.

 

 

ok well asus probe keeps gave me a 3.3v rail warning once but i guess it is fine and the software is stupid

 

thanks

First off.... Those are voltage readings at the MOTHERBOARD.  Not the PSU.  The PSU does support voltage monitoring, but you would use either Corsair Link or iCUE or use HWMonitor to read the ACTUAL PSU voltages.

What power supply tester?  How was it tested?

 

Why not use a digital multimeter if you really want to know the voltages?

What happened on your last power supply?  Why did you RMA it?  They let you RMA it because the motherboard said the +3.3V was low?  What was the problem with the PCIe cards?  Does the new PSU fix these problems which confirms there was actually a PSU problem in the first place?

the cards/pc was not being powered correctly replacing the power supply fixed the issues every time,.

 

 

il tell you about my experience with this horrible power supply and why i stopped buying enerrmax (AKA supposed high end products)

 

https://www.enermax.com/en/products/maxrevo-1500w

 

has a 5 year warranty  didnt make it to 3 worked fine for about 2  maybe 3 years it a 1500w gold i expect it to at least live though it 5 years,  i had a enermax galaxy 1000W in the past and it lasted more than 5 years. 

 

sent it back and i had to pay shipping the repaired  one comes back with a broken fan that makes tons of noise. it was also looking like it was doing the same thing anyway

 

 

sent it back

 

got brand new one in the box used it for 3 years again same problem of not powering the pc correctly  pc cards low again

 

how did i find out the cards did not get the right power? 

 

it was a sound card and a raid card i had to spares i tacked down the power supply as the problem by swapping them out. they work fine, they are pci powered so what ever rail is powering those is the problem.  and i was getting warnings about the 3.3v rail and saw it drop all the way to 1.5 or something at the end. it would slowly drop every day a little bit and get worse

 

everything works fine with a decent power supply that is working.

 

 

 

oh and enermax used to have some really good fans i used to like they now fail every 6 seconds and make horrible squeaking and rattle noises after not that long for a long lifetime fan and they are next to impossible to find too and over priced so i stopped buying those too. they are also the same fans in the psu "twister bearing"

 

O(oh and the fans had RGB lighting built in with out a controller so you could just click a button on the fan and the lights changed i liked that oh well.

 

 

 

dont buy the enermax revo power supply or the fans unless they stopped sucking and they are good again.
