im running a 8800 gts 320mb superclocked with a 400w psu, it turns off my comp

i was playing battlefield 2 on high settings with antialising on 2x pretty good...and i decided to put antialising on 8x, and whenever a big explosion happends or something like that it turns off my computer and reboots it.....im running a case powersupply that came with a 400w power supply.....this one http://microcenter.com/single_product_results.phtml?product_id=0257468......... could it be because the video card needs more power??????? let me know thanks

so your saying my powersupply gave up or my video card???????

im running

e6750

msi motherboard

2 gigs of ram 5300

160gig hard drive

80mm fan

heastink

and dvd rom

i think your PSU is giving up, its not that you video card cant handle it to be honest im surprised you dont play with 16X AA.also what monitor do you have.

its a little hp 17inch lcd screen.

i dont think it can be overheating, it happends about 3 minutes into the game.

Well you are running on a minimum amount of watts for a 8800gts, and your PSU probably doesnt have enough amps, I am pretty sure its your PSU

Upgrade your PSU, because your running some quality parts there wouldnt want to damage them, a stock 8800 needs about 400 watts PSU, and a really good quality brand, your card is superclocked which means its pulling in more watts, buy yourself a nice PSU around 500-600 watts with a lot of amps.

Well yea everything takes power to work all the components, a bad PSU can mess your computer, I never understood why some people bought uber rigs but got a mediocre PSU, its one of the most important things in your computer nothing can run without it.
