680 SLI PSU Question - Page 6

650W should be fine, just don't add alot of stuff.
When i was building my PC i was running a E8500 and a 4850 off a 430W Generic PSU, it would cut off after a overclock while playing BF3. Hence why i'm running with 750W.

You should keep the PSU, try the 680's with it and check the wall power consumption for your actual PC with them in there overclocked (if you do so). You'll find it probably will be fine, but if it's not (pulling 620+ watts). I'd upgrade to a 750/850w PSU.

Other then that the build looks great! thumb.gif

Nice! That seems rather good! Although ideally i'd be running that on a 750w unit.

Like most have said, 650w WILL run that system. The only thing I would look at would be that it has the number of PCI-E connectors you need, and the Seasonic X650 Gold certainly does. That is a very stout unit and I would not have any concerns whatsoever using it.

I do understand where toothman is coming from, but the days of needing to buy a 1000w unit just to ensure you got proper quality are gone. There is nothing wrong with buying a PSU with more capacity than you need for a new system (I'm guilty of this), but if you already have one that is sufficient then there is no reason to waste money.

This is the part where you seem to be hung up, because if you are calling any of the recommended products cheap you might want to re-evaluate your view on what cheap is. There are plenty of 1000W supplies that are crap in build.

Oh well, it seems the OP has taken proper advice given.

Wow... Your sig has a 1200w PSU? That's crazy for a GTS450 and a 32nm 3930k..
Still i guess you know that you've always got that power for 4x 680's tongue.gif

Bought the PSU for a different rig with quad SLI, didn't end up going there though. I should update my sig rig because that one is sold, I'm using a little Antec 650w right now.

Alright I'll say this one last time.

650 watts is PLENTY for SLI gtx 680's.

750 watts is great for overkill.

The reviews prove this statement, and everyone else who says otherwise is just BSing you.

There is not ONE REVIEW THAT SHOWS YOU NEED MORE THAN 650 WATTS FOR SLI GTX 680.

I warn the OP because going cheap on the PSU with a $1000 GPU setup is unwise. I hope my warning is heeded.

I'm not here to win an argument with random people.

Your use of cheap to refer to a lower wattage PSU's is absolutely murdering your own argument.
