Crossfire Fullscreen - Instant computer reboot?

Hey guys, I just bought a new cpu/mb/ram combo for my computer, and also an additional 6870 for crossfire.

When I have crossfire enabled, and try to play a game (at the moment BF3 beta and WOW) full screen, it instantly crashes (the moment I switch to full screen or boot into a full screen game)

I am not sure what is causing this, initial thoughts are power supply? I have a 560w Tagan PSU which is pretty high quality and after going through a PSU calculator apparently minimum for all of my peripherals/hardware is 450w?

Any ideas?

Thanks
 
Full specs as follows:

Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor
Gigabyte Z68XP-UD3P Intel Z68 (Socket 1155) DDR3 Motherboard
Corsair Vengeance Arctic White 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz
Tagan TG580-U15 580W ATX2.01 Easycon SLi Compliant Modular Silent PSU
HIS 6870 x 2

I really don't want to have to fork out another £100 odd for a new PSU if I can help it :/

Is there any way to prove its defo the PSU at fault?
 
It is a new windows install.

I'm currently in the process of trying the second 6870 on it's own.

I managed to get into wow for about 3 minutes earlier, ran great, then crashed again.

When trying the 2nd card on its own, should I leave it in the same slot or try both in the primary slot?

Try as many combinations as you can imo. That PSU giving out enough amps for both cards?
Click to expand...

As far as I know? how can I tell?

It was a pretty expensive PSU back in the day,

On the side, under the 12v section, is this:

12v 12v
20A 20A
35A
420W
 
Right, have tried both cards individually, in each slot, works fine.

As soon as they are crossfired and I boot up BF3 beta, or try and play wow, they fail and crash.
 
I am indeed using the 11.10 driver, freshly installed after the windows install.

Older games seem to work ok (don't know if this is cause they are not using crossfire) but as soon as I boot up something taxing in full screen, it restarts (wow runs for a minute or so before rebooting)

Everything I can see points to the power supply? :s

Any recommendations on power supply? Baring in mind that I have just spent over £500 on components, cant really afford too much more...

Was looking at maybe a 750w OCZ?
 
Man...

I think I will shed man tears if it's not.

What was initially supposed to be a £150 graphics card upgrade has turned into a £570 PC renovation :S
 
:D

At least when I come out of all this, even tho I may not be able to go out, or even eat, I'll have a beast of a computer :)
