Hello, first i just want to say that i am not a native english speaker/writer.
i want to ask why my pc turn off by itself when playing a game (with out going trough the shut down process)
my pc spec
i cute 0508ULA-5G1-BB W/power 500W/P4
HIS HD 4850 1GB
2GB ram
Intel dual core 2,8Ghz(forgot the series)
wdc 500GB hdd
Gigabyte P43T-ES3G

is it because the PSU?

More about : shut

Yes. The PSU is the most likely cause. You can check for sure by hooking your computer up to a power meter and seeing its total power draw.
I can't find the specs on your PSU, but you may be able to find them on the side of your PSU.

Also, please do not double post:

Hmm. According to the specs, it should have enough power. Being a low end brand like icute, I would have expected less. Is the problem persistent? In other words, does your system shut down every time you load it?

It could be the graphics card overheating and computer turning itself off rather than frying! This is what happened in my case, had E4650 and temps started at 90C. Used a program called Furmark and tested graphics card, temp went up to 120C in 4 mins before computer turned itself off.

I replaced graphics card on Friday and all games are running fine now, graphics temp ide 50C, when playing Just Cause 2 on full specs, just under 80C.

You can also use CPUID HWmonitor, to look at all temperatures of your equipment.

sorry man, iam really ripping you apart tonight. I really don't think 27 amps is enough to run that card. 30 amps is the minimum requirement for that card. @op Get another power supply with one that has at least a 35+ amps on the combined 12v rail just to be safe. The graphics card is probably going crazy because it doesnt have enough "juice" and making your computer bsod(a super quick one that you dont notice)


ps. those are perfect temps.

one thing you never want to do is skimp on your power supply with a build.

Yes, that is too hot. Do the following:
-Clean all dust from inside the system, especially the HSF
-reseat the heatsink with new thermal compound.

ok thx for the answer.
which brand do you recommended for thermal compound?
is it possible because my HSF and CPU was too old?(4 years old)

i'm sorry if i'm asking a lot of question.

I use artic MX-2 but you can really use any moderately known brand/model. Just don't spend too much on a "better" compound, is my advice.

Thanks for all the answer
turn out the main problem is the store which i bought my pc forgot to add thermal paste.
now after i add a thermal paste (no brand but it still ok for normal proc without OC) the temp drop down to 39-40 on idle and max load only 61C

i confused which answer should i choose as my best answer but since at first i though my problem was in PSU then perhaps the one who helped me a lot so i can pick a good CPU is the best answer.

no hard feeling for the others okay :p .

thanks again for this forum and all its member who helped me.

i think you should still replace the PSU with a better brand. I have seen those iCute cases, and they use rubbish PSU's
