Computer rebooting on games

NewLander · May 19, 2014

Hello

I have a new rig that is really powerful but I'm really frustrated because it reboots usually 5 minutes after I play games like Arma 3 , Tomb Raider.

My specs are :
-I7 4771
-16GB Ram
-780Ti
-750W Psu

It's not a PSU issue because as you can see , it delivers 750 W. I updated my graphic card drivers as well.
Anyways I've noticed it reboots (by itself) when the GPU reaches a temperature above 55-60 degrees.

What is it ? Is there a kind person to help me please?

Thank you

which 750W psu is it.

Its' a LDLC PSU. But the problem is not from here since I've installed a condensator on the rig to check if there is a lack of voltage.

you've installed a what?

change that power supply.

A capacitor !

NewLander · May 19, 2014

The presence of the capacitor prooves its not a power supply issue .

Help

how does the capacitor prove it is not a PSU issue? it might smooth any dips out but only for a fraction of a second until the capacitor is empty.

i would change the power supply.

750 watts + new psu not enough ?

daswilhelm · May 19, 2014

depends if its a good psu at this point. your gpu temps are fine, if the cpu temps are also ok, i would suspect a bad power supply.

NewLander · May 20, 2014

Cpu temps : 55
Gpu temps : 58-60

psu should be fine, seasonic oem: http://www.realhardtechx.com/index_archivos/LDLC.htm

how did you fit the capacitor? remove it.

You need to replace the PSU. It is a cheap PSU and doesn't have enough power to supply the video card. Just because it says it's "750W" doesn't mean it's good enough.

You need a PSU with at least 42A on a single +12V rail. Amperage is what is important, not Wattage. A lot of companies split up the ratings so it's not actually 750W. There is not enough information on your PSU to verify that it is good enough.. which indicates that it is a cheap PSU that is not capable of powering the 780ti.

EDIT: Take a picture of the side of the PSU and post it. We need to see the amperage ratings. You need at least 42A on a single 12V rail.

see my link above, it's a seasonic, it's ok.

13thmonkey :

Nice find. I was having trouble finding relevant info on it. It does appear to be good enough.

I suppose the problem lies with the GPU itself then. Are you able to RMA it?
