power supply overload

Hi need some advice. Right know I'm running a 700 w power supply, Intel Core 2 Quad Q9400 Processor BX80580Q9400 - 2.66GHz, 6MB Cache, 1333MHz FSB, Yorkfield, Quad-Core, two nvidea 8800gt 500mb in sli 4 gig ram and about a terabyte of hard drive over 3 drives including a 60 gig solid. I was working on pinnacle studio video program makeing a movie I looked at my processor and it was working at between 80-100% most of the time my ram was running about 2.5 gig all of a sudden every thing slowed down at first dident think any thing of it after all i was doing a lot of editing. but the next day I went to play shaun white on my computer and the thing sucked it was all jurky so I put it down to absolute lowest settings and it was no better. So I was toled that my power supply was probable broken and not sending the proper power to the mobo. so then I got to thinking my prossesor was maxed ram was running pretty high but also both gpu's were being powered of mobo. (thay don't have aux power)

I if this power supply comes bake toast it would be the 3'd I have fried with theses sli cards could the gpu's be the problem ? sould I get one that has aux power? I was looking at just one card not sli. I was looking at this one at tigerdirect (BFG BFGEGTX260MC896OCDE GeForce GTX 260 Overclocked MAXCORE Video Card - 896MB GDDR3, PCIe 2.0 x16, SLI Ready, (Dual Link) Dual DVI, HDTV, Dual VGA Support

thanks Jarren

does the mobo have an aux power port for the sli cards or are they straight up juicin' off the pci slots?
are you over volting or overclocking anything?
is anything getting hot?

there is only a square 8 pin that Is for cpu and 24 pin for the rest.

I have lots of air movement two masive fans one front one back plus a regular side fan and a big copper heatsink-fan on cpu and a two fan 700w ocz gaming power supply.

and no overclocking or overvolting

what brand power supply are you using.
if you are burning up 700 watt power supplies i wouldn't point fingers at the video card as it isn't directly drawing from the power supply.
i would first point at the motherboard or cheep power supplies.
try running an enermax or ocz or antec power supply if you are not.

i used to put in cheep power supplies when i first started building systems but now that is one place i won't skimp to save money.

odd, most 8800s require direct power from the PSU. In any case though, if you got a cheap PSU that would indeed burn through them. You can't just look at the wattage when you buy a PSU, you also need to check the amperage, particularly on the 12v rails. Your probably going to want a PSU with a MINIMUM of 30-35 amps (combined) on the 12v rails. A good brand like ANTEC, OCZ, or COOLERMASTER would be along the lines of PSUs I would recomend.

Okay Here the update I'm running an ocz gaming power supply I got it tested and they said it was really stable. I'm running a nforce 750i Sli Mainboard.

Most things seem to be good I burned CD's last night were real fast. Things are running smoothly except for games

hold on i think it might be fixed I had a registry cleaner screw op my computer and when I installed some games again for example dirt 2 I runs awesome. will get back to you for an update

hmmm.........that'll do it.
i'm not a huge fan of reg cleaning.
it used to be a big thing back in win95/98/me but now with xp and vista i don't think it is a big deal.

FWIW: For a number of good reasons, BC does not recommend the use of registry cleaners.
