GPU freezing and 12 volt

I was trying to put together the best budget pc recently and wanted to escape with a bare minimum PSU.


Runs 3.3v 20a
5v 25a
12v 29a (1 rail)


ATI asus 6850
intel i3
intel motherboard

Intel active monitor will display the 12v idle at 12.109.
Under high gaming stress the 12v will dip below to around 11.80's. The game will randomly crash, after a few minutes of play. Can a voltage that stays below 12 cause the graphics card and system to crash.

Are you supposed to have a reserve amperage for your system to run stable, instead of using around 80% of the 12v's amps like i most likely am on high load.
 
Please post the exact PSU model and make.

29A is insufficient really for that GPU, however lets see the exact specs.
 
Seen those on sale for 19 bucks. Dont know if thats your problem. But I would definitely get a better power supply.
 
cheap supplies use cheap components which can lead to poor power regulation. does that help?

step up to a corsair tx/hx series or even a builder series and your problem will likely vanish.

Its made by ToPower, which makes from cheap pieces of junk up to moderately ok units. This is one of there junk ones. It only has 348W on the 12V rail and that is a max. It would probably trip or overheat before it could even pull that much.

Or more likely it would blow up and take half (or all) his components with it.

Only basic ATX design standards
No power factor control
No under voltage protection
Short warranty
Poor voltage regulation
Small (120mm fan) = noisy

need I go on?

Strangle, you miss spelt PooPower:

To the OP you need something like this:http://www.newegg.com/Product/Product.aspx?Item=N82E16817139019 as a minimum. Just a word of warning you are risking all your other components with that PSU. I wouldn't even turn that machine on if it were mine.
