Will a Kentek 775W PSU handle my rig?

I recently made some upgrades to my system (added a radeon HD6850 for crossfire, a few fans, and an i5 2500k cpu) and everything was going smoothly for a few minutes after boot-up until i got a blue screen. The pc then turned off, then on, then off and on again until i shut it off. I thought my PSU (the kentek 775W) might not be able to handle what i was throwing at it so i took one HD6850 out and booted up. i got a message saying i recovered from a problem and it said this:

Thats all i really know at the moment. So far it has run fine with one GPU out, but i cant tell if it was a software issue or if my power supply couldnt handle it.
My specs are:
Spoiler
CPU: intel core i5 2500k
GPU: Radeon HD6850(X2)
Motherboard: MSI P67A-G43 (B3)
PSU: Kentek 775W Modular
RAM: 2X4GB Corsair XMS3
1 CD/DVD drive
2 HDD
5 case fans

Any help is greatly appreciated!

You would probably want to swap that PSU out ASAP.... probably a generic '775w'...

I don't think it can even provide close to 500w IMO.

Wow, that is a terrible PSU.

24A each on the two 12V rails (equaling around 45A combined), for a max output of 540W on the 12V rails (and I would definitely say that that's a max rating and certainly not continuous). Pitiful for a supposedly 775W PSU.

Still, I wouldn't Crossfire with that PSU, even if it was capable. From what I can tell about it, it's liable to make a nice little light show for you at any moment.

Suggestions on a good power supply for what I have?
And I'd rather not spend a fortune if possible...

Even if I'll be overclocking the 6850's and maybe my cpu?

Well, there's two of us here, lol, but yes, the TX650 would be fine, as well as any of the ones that I recommended.

And you edited that post just as quickly, lol.

650w would do fine, however, you may want to consider Dj's recommendation of his 750w PSU's :) 

They would provide more headroom to OC your GPU's and CPU along with some peace of mind for future CF/SLI configurations.

Yeah I just realized that both of you posted, haha. Tried to edit that out before you noticed.
Thanks for your help guys, I'm off to buy a power supply.

Against a semi-modular Seasonic built Antec that provides basically the same electrical performance and a pretty blue led for lower upfront and overall cost ?

I'm not much for the "pretty blue LED", but otherwise, I suppose you're right. Of course you can get one without the blue LED for $99.99.
