Yeah, 850W should be enough... try undervolting them and see if that fixes it?

Sounds like a PSU issue though. The temps on that card are not ideal, but it shouldn't be causing a shut-down...

AFAIK, you should see the GPU go "SICK" or "DEAD" in CGMiner before it would ever cause a complete PC shut-down.

I think the XFX card is running at 0.9 or something already. They should be able to run stock though right?
If my PSU is failing why has it never done this before with 1 card?
Could it be that the PSU cant supply enough amps on the 12v rail?

Have not seen cgminer do that so I think it is PSU. Either way the XFX DD stock cooler sucks anyway lol.

The CPU thermal threshold powering down isn't a shutdown, it just turns the PC off. I should have been more specific

It doesn't sound like that is what's going on here though...

In your first post you mentioned the Sapphire card won't work correctly in the top slot and now you've said the XFX card won't work in the lower slot. What driver version are you using? And are you getting the drivers from Sapphire/XFX or are you just running the ATI ones and CCC? This very well could all be PSU related but I feel like there are too many other funky things going on for me to give up on troubleshooting!

Yeah, CPU and mobo temps seem real good to be honest. Dont think it's that.

It works, but it windows acts as if there is no driver, already have the CCC and ATI drivers in there, works fine on the XFX card, do I need to re-install them or something? If I could get that card to work in the first slot that would be good, the cooler on the sapphire will be good enough to get 450kh/s at least.

Think I might sell the XFX card.
