Is my 5970 dead?

[macbook-air]

I recently got a MSI 5970. My PSU is not powerful enough so I plugged the mainboard and the graphics card's PCI-E 6-pin to one PSU and the 8-pin to another. In case of power failure, the card usually has a red LED on. But this morning, when I was trying to turn the rig off, I first removed the second PSU (PCI-E 8-pin) then the main PSU. The graphics card then never back on. A system reboot result of no signal, no BIOS power-on self-test, no one short beep from mainboard. Is it recoverable?

Depending on how strong your primary power supply is, it's possible that it's damaged from being pushed too hard.

I once mined with a 5850 with an old 330W PSU for about 10 hours before it failed.  The PC would kind of turn on (fans spinning), but nothing would happen.  I replaced the PSU and everything worked fine.

If you have a weaker video card available, give it a try, and use the secondary PSU to power the whole system.  If it works, you know the problem is either the 5970 or the PSU (more likely?).

I have four 5970s actually, two were damaged this way. It's so bad... I sometime hotplug my 5830s to PSU and PCI-E and they are still working very well...

Whoa, hold on a second.  You have 4 5970s and you already damaged two of them because of an inadequate power setup?!?! Dude, do yourself a favor and get a decend power supply ~ 1000W and up!!! Stop killing the 5970s -it's a crime and you should be arrested lol
