You wont believe what happens.......after a few min. one of two things happen. My pc shuts down completely, or it just reboots itself.

Right off hand does this sound familiar to anyone?
I setup PhysX to run on the onboard nvidia 780a chipset, and have SLI turned on.
this happened with my Phenom@3600mhz, and at stock.

Your power supply is the issue. Not enough juice.
Also add some wattage if you have overclocked the cards.
I would go for a good 800w

looks like 19, is that not enough?

edit= just found out that each card pulls 180w on load. Maybe I should try installing win7 instead, or vista and see if I get the same problem

I would not say it can. I had a 600w psu that could not handle two 9800gtxs in sli.
System will turn off when under heavy load in the benchmarks, eg the grand canyon test in 3dmark.

Same issue, in 3dmark 06 the pc would turn off, as soon as the "dragon" came out of the water.
So now I can't even use the brand new 275, until I have enough saved up to get a new psu. That sux

Thanks for the help

Looks like a PSU upgrade for me also before I get my 275's - Im on a 600w as well.

Would a 600w be able to handle sli'ed 260's though?

Hmmm, well my 650 could handle my 2 9800GTX+'s
in SLI just fine. But they only required one 6-pin each. It seems like that was what my PSU was made for. Adding the adapters to power two 275's I actually had to remove the 8-pin from my board, and use the 4-pin in its place just to get it to boot.

So if your 260's have one 6-pin each then I know your psu can handle them.

side note, i even unplugged my raid array (four 7200rpm seagates 400gb in RAID0) and installed on one 300gb seagate just to see if the cards+HDD were causing the problem. Well it didn't matter, trying to run any graphic intensive software causes computer to shut off. So there is no doubt about it, need a better psu. Gonna try to find me a 1000watt (at least) gives me room to expand later

hmm can a 1000Watt PSU (written in my rig there) support 3-way SLI for GTX275 D:?

I would say most defiantly yes.

yea Deffo

[Newbie2009]

im currently running 740/1515/1140.
Runs perfectly.
Core clock wont go any further.
But the others will go up a lot more without any problem, except one. On 3d mark 06, the last snow one part, blue blobs/lines(not typical artifacts) appear.

What does that last test push exactly?

[apt2vanish]

My 275 overclocked on my other system-
core750 - shad1600 - mem1250 = Crysis@29.01fps
