Acceptable voltage variation ?

post #1 of 5
Thread Starter 
Hi smile.gif

I recently have had reboot problem when gaming (freeze, black screen, reboot). So, i checked the voltage to see if something is wrong.

I got those value :

Voltage 0 3.33 Volts [0xD0] (+3.3V)
Voltage 1 1.38 Volts [0xAC] (CPU VCORE)
Voltage 2 2.32 Volts [0x91] (VIN2)
Voltage 3 1.29 Volts [0x6E] (VIN3)
Voltage 4 3.78 Volts [0x5A] (+5V)
Voltage 5 16.19 Volts [0xB8] (+12V)
Voltage 6 3.38 Volts [0xD3] (VIN6)
Voltage 7 3.33 Volts [0xD0] (VSB3V)
Voltage 8 3.36 Volts [0xD2] (VBAT)
Temperature 0 41 degC (105 degF) [0x29] (TMPIN0)
Temperature 1 31 degC (87 degF) [0x1F] (TMPIN1)
Fan 0 1207 RPM [0x4DB] (FANIN0)
Fan 2 3529 RPM [0x1A9] (FANIN2)
Fan PWM 0 66 pc [0xA9] (CPU)
Fan PWM 1 66 pc [0xA9] (System Fan 1)
Fan PWM 2 66 pc [0xA9] (System Fan 2)


Can someone tell me if you see something wrong ? I don't know what are the acceptable values for the different voltages, so i went here and ask for help.

Thank you for the reply smile.gif

Where are you measuring it and how?

1.38 Vcore is high for a lot of systems.
5V at 3.78V fail.
12v at 16.19V, WTH, fail.
...

Just remove the PSU, run it alone and measure it using a voltmeter. If stuff is out of spec, toss it and get a new one. You can look up the precise tolerances but overall anything above 5% is bad IMHO.

Would also be somewhat helpful if you listed the full specs of your system

Installed HWMonitor

Voltages information are taken from the list under the name of the computer.

BTW, my computer is 7years old and i can understand that it's time to change my PSU.

Edited main thread with my spec

Software readings are known for being inaccurate
Test your PSU with a digtal multi meter
