SLI 680ftw 4 gig and Seasonic X650 Is this enough to power my system?

post #1 of 10
Thread Starter 
I'm running a 2700k, 16 gigs Corsair Dominator Platinum, Dual GTX 680ftw 4gig in sli, 6 120mm fans, and a 355 pump for my wc system. I have this Seasonic X650 in a system with just a single 680ftw and want to add the 2nd one since it's just sitting in my closet doing nothing. I'd like to save money by not buying another psu since I also have custom sleeved cables for this particular psu. Do you think I will be safe with 650 watts with this system? Also, if I do get say the Seasonic x750 would it use the same cables so I could at least still be able to use my custom ones? Thanks!

not sure i know that at stock clocks you'll be cutting it close but since you are running a pump and everything i really wouldn't know

^ I think that you might be pushing it with the listed hardware, but I'm sure Shilka or TwoCables will chime in. Any overclocks on the CPU and on the (planned) GPU's?

As far you dont oc too much the cpu/gpu a 770/680gtx sli uses under 580w on load

Ok thanks for the replies
post #7 of 10
I did this on my Corsair AX650, same guts as your X-650:



My cpu was near 1.7v for this run too, and no shut downs or issues. I still have the psu in another rig now on light retired duty.

So in other words, more than fine. Unless you really push the voltage on the 680s somehow past 1.25v and beyond.

Thanks! Nah I dont plan on pushing things too far, just a bit of gaming and some regular school use.

Yes I do plan on oc'ing the gpu's and cpu. Not anything too high for instance the cpu to maybe 4.6 and the gpu's to 1200 core.

By way of update, I have everything put together and the system seems to be running fine with that PSU.
