Hello there. My GPU shuts off during gaming usually after 20-60 minutes. When I open the case everything is still running except for the graphics card. I have all of the latest drivers. The temperature reaches 48C at highest.

The game is Darkfall Unholy Wars. System Req's=
Windows XP Service Pack 3, 32bit
Intel Core 2 Duo E6850 + or
AMD Phenom II X2 +
4GB RAM
nVidia GeForce 8600 + or
AMD or ATI 4850 +
DirectX Sound Card
12GB Free Space


My system specs are as follows:
Windows 7 home premium 64-bit
Athlon II x2 260 3.2ghz
16gb RAM
Gigabyte ATI Radeon HD 7850 2g OC edition
120 GB SSD

Power supply:
Raidmax RX-580F

I suspect the power supply may be inadequate. The specs of the card on the gigabyte website say it requires a 500w power supply. This power supply says 580w, though it is a little old.

Would it make sense that the card would demand more power than the PSU can handle, therefor the psu simply stops supplying power to one single component (the GPU)?

Also if i 'stress' the pc and continue to restart it and go right back into gaming, it will crash on a more regular basis until the PC simply will not turn back on again. Then I have to unplug the power supply and wait for a few minutes before it will respond.

Is all of this consistent with an inadequate power supply? I just don't want to go out and buy another component to try and solve this problem when I'm not very sure what's causing it.

Thank you!
 
Solution
this is your peak power when new
+3.3V@30A, +5V@45A, +12V1@18A, +12V2@16, -12V@1.0A, +5VSB@2.5A
if you are down into the 20's amp on the 12v rails then you may be running short on power.

the most important thing is the manufacturer; seasonic and super flower are very good as are others. XFX power supplies are usually on sale and are made by seasonic.

the second most important thing is the amount of amps on the 12v rail.
amps*volts=watts so;
30 amps * 12volts = 360 watts

I'm not sure what you mean by "if you are down into the 20's amp on the 12v rails".

Also with these numbers and letters "+3.3V@30A, +5V@45A, +12V1@18A, +12V2@16, -12V@1.0A, +5VSB@2.5A" What would be an ideal reading, on a new PSU, to support this card? Does each of these rails represent an output for different components of the machine? Does the 12v rail represent what goes out specifically to the GPU? I'm sorry I have a very weak understanding of how these things work.

Thank you so much for your response.

Also, if the power supply is sufficient and i am incorrect in assuming it's the problem. Would the CPU be a possible weak point considering that it barely meets the system requirements? When running the game and peaking at task manager the cpu graph is quite high (between 80-100%). Would the cpu overheating account for the computer shutting off and not responding, for a few minutes, when i press the "power" button? Looking at the system specs, which would you consider more likely?

this will tell you temps

if you think your cpu is overheating then use this to push your CPU to its limits and watch temps

to shut the above program off you need to right click on the icon in the taskbar and end it from there.

also if you really want to understand power supplies then this post should help. there is a fair amount to explain and not really knowing what you do understand makes explaining everything kinda long.

so just go through a few of the links and you will be more informed than 99.9% of the population.

if you unplug your GPU does your computer have any problems. if you are stable without the gpu then it is your GPU or the power supply i would assume

and even if your CPU is weak then it would only slow performance it should not shutdown your computer.
