I've already got one GTX 780 and I've got another one on the way. I'm water cooling my 780's and because the the RIVE's PCI-E slots are spaced out, you've got to use the first and third slots to use the 3 way bridge and use pci-e 3.0. Because of this imbalance, I impulsively bought a third GTX 780 and 3 waterblocks.
Thus, I'm going to have 3 GTX 780's and a 3960X on a Rampage IV Extreme board. It then hit me that I'm pretty much going to make my PSU scream out "uncle" if I ever bench the system. I've got a Seasonic Platinum 1000W PSU and I currently idle around 180W with a GTX 780 and a 3960X at 4.8 @ 1.43 vcore (measured via multimeter)
Judging from this 3 way SLI Titan review, it appears that their 4.6 3960X @ 1.40v and triple Titan's consume about 843W for the entire system. The 106% max TDP limit caps the card at a theoretical a 265W * 3 = 795W
I've got a very solid, if not one of the best PSU's on the market but I'm kind of worried that I might be pushing over 1KW of power if I go full tilt. I've got fully braided single sleeved cables, the ones where you can't see the heatshrink, for the PSU and it actually probably cost more than the just the PSU. Seriously, I probably spent close to $500 on the PSU and cables. I'm extremely reluctant to switch the system out. Thoughts about any of this? Edited by Syan48306 - 5/27/13 at 10:41am
