Are these voltages ok?

[newalpha]

I have installed a new PSU and everything seems to work ok. But I don't know if these values are ok or not:

ORIGINAL >>> MY PSU
+3.3 V >>> 3.34 V
+5.00 V >>> 4.97 V
+12.00 V >>> 13.25 V
-12.00 V >>> -13.85 V
-5.00 V >>> -5.81 V

I think that the values of +13.25, -13.85 and -5.81 are excessive. But I don't know if that's dangerous for my PC. The CPU temperature hasn't been increased with the new PSU. And the BIOS Hardware Monitor doesn't show those values in red*, so it seems to be tolerable.

* According to the MB manual, the hardware monitor shows values in red when they are out of range.

What do you think about these values? Are they normal? Do I have to worry about something? Any comments are welcome. Thanks in advance!

I would think those values are a bit high. What PSU do you have? I would keep a close eye on it. The PSU may be defective.

Hi davemar! It's a Levicom Silent Line 380W. Do you consider that those values could be dangerous for components?

 

[davemar14]

Where are you checking these values? The BIOS? Also, what motherboard do you have? You could try another program like Motherboard Monitor to see if that gets the same values. It could be just the program showing the wrong values. 13.25 is definetly not within the 5% margin,let alone 10%.

I'm using Motherboard Monitor (MBM) and I've also compared the values with the ones showed in the BIOS Hardware Monitor. I have an ASUS A7V333. The values in MBM and in BIOS are similar so, unfortunately, I think they aren't wrong

I read that if voltages are excessive, the CPU temperature would be increased very much, but I have a normal temperature for my CPU. So, according to that, the values are not dangerous. But I'm not sure about that. Do you consider them dangerous?

Thank you for your help

"I read that if voltages are excessive, the CPU temperature would be increased very much" is true because if your voltages were high, your voltage to your CPU would also be higher. That means that more heat will be generated. You didn't mention your CPU voltage and the type of CPU you have. I am not an expert at what point voltages will cause damage. Maybe someone else has some input.

My CPU is an Athlon XP 2000+ (Palomino series). The VCore value (according to MBM) is about 1'80 V, and the original value is set to 1'75 V. I don't know if that difference can be dangerous for the CPU or not.

Thanks for your time, davemar14.

Well, the Vcore looks good. My Athlon XP 2400+ stock VCore is 1.65 and mine runs at 1.69. So your's is fine. A little over usually adds stability. You may want to check with the manufacturer and see if the 12V rail are acceptable numbers. I will try to do some research in the mean time.

I would have zero concern, most 12v devices are designed to accept 12v battery voltage. And 12v batteries are 13.8v, fully charged.

Davemar14, I can't find any additional info from the manufacturer.

Crashman, thank you for the info I was worried about those values.

Well, the CPU temperature is OK, and I haven't had any problem with the computer, so I think everything is OK and I don't have to be worried about anything related to this PSU

Thank you davemar14 and Crashman for your help. This forum is simply the best thanks to people like you. Bye!
