Overheating or Lack of energy?

[BelayaSmert]

I have a problem,

When i play games, rarely, the PC restarts alone, i don't have energy problems in my house becouse the power doesn't go off becouse the monitor keeps on while de CPU is off

This happens VERY rarely becouse it happened this morning but it didn't happened like in 2 weeks.

Also:
My case is an Cooler master Elite 430 Black
My VGA is an ASUS 7870 2GB GDDR5

Do you think is the VGA? Because it goes like 70ºC or more while playing and the normal temperature of the VGA is 28-32ºC

So i need help because i don't know if my power supply is weak (600w certified Cooler master) or is the temperature in general (25º-33ºC external)

Comments and help will be very appreciated, sorry for my bad english

It only happens while gaming?

Yeah

What model of cooler master is it? They have some models that deliver dirty power when put under a load and could cause the system to shutdown/restart. 70°C should be just fine for the gpu when under a load.

Have you used GPU-Z to monitor voltage? I was using an older PSU with my HD 7870 and it had the wattage (750W) but perhaps not the efficiency and amperage on the 12V.

That PSU should do the job just fine. You might try disconnecting and reconnecting all of the PSU cables running to the GPU. Make sure those suckers are seated properly. The temps you are listing are ok, so I don't really see it as a thermal issue. Have you overclocked any components?

NOTE: It seems that the PSU you have is relatively inefficient (70%). You might not be getting clean and efficient supply to your GPU...may need a better quality PSU.

How should i set this? I don't want to overclock but i don't know how to manage this (Mid thing)

EDIT: The minimum of Watts required by the 7870 is 500

This is my PSU http://www.amazon.com/Cooler-Master-i600-Bronze-Warranty/dp/tech-data/B00CY95QB8/ref=de_a_smtd

I would try and find the same or similar/better PSU at a local computer parts store (if at all possible) and try it out. You may have a dud/low quality PSU. If it does the same thing on the new PSU, then things may be more complicated.

The calculator at this link will help you figure out the total wattage you need:

This article from Tom's will explain why you ought to get a good power supply, what you should look for, and who to buy it from:

This is all if you determine that your PSU is the root of the problem. You could try increasing the power influx to the card via MSI afterburner.
