Hi everyone! I'd like to get some help on picking a power supply for this rig:

CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155

Motherboard: ASUS P8Z77-V PRO LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel

PSU: ?????????

CPU Cooler: Noctua NH-D14

Memory: I have 4 x 4gb of some kind of kingston hyper-x brand DDR3 1600MHz
This is in my current build and I'm planning on putting 2 pieces into the new build :) 

SSD: SAMSUNG 840 Pro Series 128GB SATA III MLC

GPU: MSI Gaming N760 TF 2GD5/OC GeForce GTX 760 2GB 256-bit (got it right when it came back in stock :D  )

Case: COOLER MASTER HAF 932 Advanced Blue Edition

P.S. I also have a 1TB HDD that I use just for storage.
-I also plan to do an SLI configuration with another gtx 760 eventually. Here are the two PSUs that I was considering:

Those are pretty decent choices but they are definitely over kill on the wattage for this build. The Seasonic is nice but better yet split the cost difference on these two you have here and get this. This build will have a better efficiency rating with this PSU and last longer too.

It gets stellar reviews from many a hardware benchmarking sites.

Seasonic SS-660XP2 Platinum 7 year warranty.

Sorry for such a delayed replay. The answer is yes. GTX 760's have a 170w tdp. Thus two in SLI is 340watts, and your i5 with a modest OC to 4.0ghz your going to be looking at 160w-ish tdp. Everything else pulls very little power fans 5-10w, hdd's 10-15w, good ssd's 2-3w.

Really if you have the extra money just get a better gpu now. Everyone always plans to SLI and never do until years later. Years later availability on the gtx 760 could be slim to none, or used. The new equivalent 760(gtx 960 or whatever it ends up being) will certainly be more powerful than sli gtx760. This is because new games and drivers are optimized for new hardware and not years old SLI set ups or xfire setups for that matter.
