Thanks guys

More than enough psu power for what you have proposed.smile.gif

Ran 7800Mhz now for some hours on 65% without a hitch.

thats a great 650 but if you plan to add volts and overclock..i would def buy at least a good quality 750. or an 850 just for the hell of it.and there not that much more money.i think overclocked they run about 250 300maby.. on top of what else you have in your rig...

Quality is important since a lot of like 800w power supplies wouldt even do 600w on the 12v.
Theres even a 1200w cant do something like 800w tongue.gif.

Really watch out before buying a PSU.

I would recom Silverstone Strider 850, their PSU's run even above specs biggrin.gif. I got the 1200w Strider Gold.
Always go GOLD at least or platinum

He should not buy an 850w unit for just the hell of it.

His 650w unit is more than enough for two 1400MHz( if should get lucky ) Lightning 680s and a 3770k period.

I run my 3960x with my gtx 690 off of a 650w that is virtually the same psu. A gtx 690 is two gtx 680s on one pcb incase you didn't know. Now maxing the slider in afterburner in the voltage won't push a Lightning to 300w, that's for sure. And a 3770k takes like 100w. Maybe a tad more with a 4.7GHz OC.

Here's my 3dmark11 score with my current set up:



Computer would have just shut down during that bench if 650w wasn't enough. And I'm sure I can run a 550w with my rig if I needed to, as along that it was a good quality unit.

I am far from knowledgable on PSUs and will list the difference in my overclocks.

3930K @ 5.0 (1.495V) 2*680 @ +180MV = 1150W from the wall. I listed my specs for no overclock and I am aware that the 3930K uses more watts than the 3770K but it doesn't leave much headroom if he wished to try over volting.

I read a review where a lightning power draw is up to 400watts

See the volts through my 3960x in that screen?

These psu questions should be asked in the psu section:

Yep and nice OC on that CPU thumb.gif

I agree that question should be in the PSU section and I did say I know nothing about PSUs. I was just giving my wall readings and that may have given Rube who asked the question a rough idea of what he needed.
