Computer shuts down when playing games. (Think its my PSU)

davvern · Jun 4, 2015

My computer:
Pressesor: Amd fx-6300
Motherbord: Msi 970A-G43
Grapic card: Nvidia Geforce GTX 660
PSU: SFC 600w

Computer shuts down after ca 5 min when playing FPS games such as BF4. If i turn down the grapich enough it may not shut down.
- I have to unplug the power cord and plug it in again to power up the computer ather shutdown.

I know i have a pretty unknown PSU and thats why i belive the PSU is the reason. I just wanna be certain since im a student and dont wanna waste any money. xD

Voltage reading form HW Monitor:
+3.3V : 3.31V
Cpu vcore: 0.90V
VIN2: 2.18V
VIN3: 1.31V
+5V: 3.07V
+12V: 13.82V
VIN6: 3.14V

Im not an expert and that why im asking here: But from my little knowledge isn`t +5V and 12V far off ?

Have you checked the temperatures on the cpu? Are you using the stock cooler?

Holly cow your voltages are off. you should be within 2-3% of the actual voltage.

5 volt should be 4.85v min 5.15v max not 3.07v
12 volt should be 11.64v min and 12.36v max not 13.82v

I would replace ASAP, that's not good for your computer, Things are straining for power on the 5 volt and getting over voltage on the 12v.

Check cpu and gpu temps. If ok then certainly power supply is too weak or starting dying.

faalin :

HWMonitor is known for showing wrong amounts. Especially on AMD builds. So they might not actually be a problem.
They would have to be checked with proper meter.

The "I know i have a pretty unknown PSU and thats why i belive the PSU is the reason." which turns into I have a generic PSU and is junk.... no offence.

Try asking one of your friend if you can barrow their PSU to test out your computer. Make sure its a good quality unit.

Also let us know what your cpu and GPU temps are.

SFC is bottom tier garbage. It's one those avoid at all cost PSUs.

A good 400W - 450W PSU that has a maximum combined +12 Volt continuous current rating of 26 Amps or greater and has at least one 75-Watt 6-pin PCI Express supplementary power connector will do the job.
