ATI 6850 12v Problems

post #1 of 2
Thread Starter 
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)

http://www.newegg.com/Product/Produc...82E16817101050

ATI asus 6850
intel i52300
MSI P67A-C43 Motherboard

12v idle at 12.209.
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.

I dont understand what PSU i should be purchasing for this system, should i get a 4 rail 12v psu? HELP

Never ever go cheap on a PSU. It could cost you your whole system and hence defy the purprose of saving money on a PSU.

Look for better brand names like Antec or Corsair and for at least 500~550 W.
