Computer Crashes

If all three of them ran succesful with no hiccups, try running the CPU and Graphics both at the same time. If we experience a shutdown we can safely assume it is not software related with your games and it's likely hardware related.

I just noticed you said "i got the 600-650W used without my tower include."

Your system is very likely going over the 500 watt, i do not know how much it is requiring when going full load.

Since you got the power supply used the capacitators may be loosing efficiency and although it might have been a 650 PSU at one point not so much anymore.

This could very likely be the source of the problem.

Anyway you can find a friend that would let you borrow a power supply with much higher wattage rating?
If not how about unplugging as many possible cooling fans you can and still maintain proper airflow. Unplugging optional drives CD/DVD

I counted 6 Fans which could probably at max use 30~50 watts.
DVD drives possibly 20 watts

If any overclocking was done please revert it back to normal, overclocking really increases power consumption.

How much wat PSU would you prefer for my computer?

try using this PSU Calculator. I ran your system specs and came up with 513W. You could have other components not in the specs. But, 513W does push a 650W PSU. You are running it at 80% of it's capacity. If you are overclocking, that could put you over the top. I like to run a PSU at around 60% of capacity. That will make it last longer, run cooler and allow room for upgrades.

Also, how long did you run Furmark and memtest86. To run memtest86 for 7 passes takes from 8-10 hours.

I ran the memtest once, and my computer scanned my computer 2 times. The Furmark was running 15min on 81 decrease.

I will try the program you sent me.

I also just took away afew fans and played a game in battlefield 3. My GPU went to 60 - 61 decrease and 44% fan speed.

I could play a whole game without a crash. I usualy get crashes or a freeze before the game is over.

I tried that calculator aswell. i also ame up with 513W. Then i tried 2 recommended calculators. I could choose exactly what i had in my computer without my tower. The first one told me i used 600 and the other told me i used 650W that.

If your card does not have it's own utility, you can use MSI Afterburner to set a custom fan profile that may keep your GPU cooler. You just have to run a balance between fan speed/GPU temps and noise.

that is a pretty comprehensive calculator. many calculators overstate the wattage to get you to buy a more expensive one. If you decide on a new PSU, I would recommend Corsair or Seasonic. They cost a little more but are very good quality and will put out what they say they do. Some PSUs don't actually put out what they are rated at.

I just tried to disable the 3 big fans. my pc crashed after 1 or 2 hour.

To be honest. i think my pc reaches around 700 - 800W with all fans on.

I will put some money into a 850W Power supply.

essenbe · 12 Feb 2012

fans really don't pull that much power. I have a HAF X case with 1 230mm 3 200mm and a 140mm. I'm running a CPU cooler with a 140mm and a 120mm fan and have a GPU cooler with a 120mm fan. I run 2 SSDs and 4 X 1TB 7200 RPM hard drives an AMD 6950 and am overclocked and don't need that much PSU wattage. I have a Corsair HX 750. It may be your PSU, but before spending money I would do extensive tests on other hardware to make sure that is the problem.

I think you are making some rank guesses.

You may have a power supply problem, but your system isn't using 600 watts. Quite possibly not even 450.

If you want to measure actual usage, use a Kill-a-watt or similar device.

Your PSU may not even put out an honest and consistent 400. Get a reliable brand---if you decide you have a PSU problem at all.

The PSU calculators try to give you a recommended PSU wattage to purchase. They do not estimate power consumption.

Your PC crashed after a few hours while gaming again?
I also read a post where the test were not that extensive. I know you may not like waiting for your computer to do these test or you may have other thinsg you want to do but, all i am doing is trying to save you money. What if you buy the power supply and you still get crashes?

However you mention you were able to play a game of BF3.
You never replied to me is that power supply a used power supply before you bough it? If it's a few years old i can see the possibility of it not being able to power up your system.
