I am planning a new build and would like some suggestions/recommendations as to a suitable PSU and CPU cooler. My current system plan is:

i7-2600K
Asus P8Z68-V Pro/GEN3 MB
2...GeForce GTX580
Corsair Obsidian 650D mid-tower case (no room for a full tower)
Corsair Vengeance 1600 16 GB
SSD (TBD)
2...2 TB Seagate Barracuda XT, 6 Gb/s
Samsung SH-S222A ODD
3.25 "floppy drive (TBD)
SB Xi-Fi Titanium sound card
win 7 64-bit and Ubuntu dual boot

PSU: Taking into account future expansion I am looking for a 1200 watt PSU -suggestions?

CPU Cooler - main concerns efficiency and will it fit into above MB/case/RAM combo?

what will you use this on? there is no need for the 2600k
16 giga ram is overkill
floppy? :) )
you won't be needing a discrete sfx card
cooler either xigmatek aegir or corsair a70
even 1k watts is enough considering you will overclock the whole bunch

Well, the Mobo has 7 Slots on it and the Case has 8. If you run the SLI setup you'll be needing to put them in slots Pcie 2.0x16 1 & 2 on the mobo which correspond to expansion slots 2 & 5 of the Case that leaves you with a single slot gap between the 2 cards. I guess that's ample airflow space between the cards on the mobo.

You won't need a FDD since the mobo doesn't have an FDD header all together.

Putting all that stuff into the Power Supply Calculator I'm getting a total of 997W, so you ought to be really pretty safe with a 1200W PSU and not sorry Since the rig is going to generate quite a bit of heat, you are sure going to be putting in an extra fan or two. The 1000W suggestions from newegg were seen and I could find only a few good ones there

Now this is supposed to be good by public opinion running your config but doesn't fit into the standard case, since it's Exclusively designed for a few Antec cases
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

For that amount of RAM you need to check the Mobo manual as I am doing now to see what 1600 RAMs are supported by this Mobo and from which companies in what configs. You need to select RAM that works with less than 1.65V of power not equal to that. SO there are very few options 2 from Corsair, 1 from G.Skill
CMZ8GX3M2A1600C8(XMP) 8Gb 2x4Gb Corsair
CMZ8GX3M2A1600C9(XMP) 8Gb 2x4Gb Corsair
F3-12800CL8D-8GBECO(XMP) 8Gb 2x4Gb G.SKill

Of course there are a lot more RAMs mentioned there but they are all 1.65V.... which would be adding to a lot of strain on the MemController in the CPU leading to Higher Temps.
As long as you can manage the OC and the timings the RAM shouldn't be that much of a problem.

alyoshka - Thank you so much for the very helpful information.

With regard to the 1.65 vs 1.5 V RAM issue, I have seen on another Tom's Hardware thread a post indicatiing the Asus and other MB manufacturers have confirmed/claimed that there are no problems with 1.65 V RAM on a Sandy Bridge MB. I have also seen posts elsewhere that claim the MB automatically scales the voltage down to 1.5 V and that you have to go into the BIOS if you want to set to 1.65 V.

Any thoughts or comments would be greatly appreciated. Some quick Googling gives me about a 50:50 split that 1.65 V is either good or bad on a SB MB.

If you use a 1.65V RAM module and the Mobo under volts it automatically... what will you get? running at 1.5V..... it's going to cause black outs...
Yes, in mos of the mobos you will need to set the voltage to 1.65 in the BIOS.
My suggestion is 1.65 isn't so good that you need to go through all the heartache that it might cause if something doesn't mix'n match in the rig.
I think most of the parts we discuss here at Tom's are in regard to what the Manufacturer's have claimed/confirmed. :)  If their claims were that true as we'd like them to be.... we'd have a lot less questions here at Tom's I think....

Thanks again alyoshka and great point about manufacturer's claims. I will be going with the Corsair 1.5 V RAM.

Also going with the Corsair AX1200 PSU and Cooler Master Hyper 212+ CPU cooler thanks to other suggestions from the group.

Thanks to all for your assistance.

Just purchased a Xigmatek Aegir from Amazon. So far have spent an hour trying to fit it without any success. Not enough clearance. Will make a further attempt tomorrow and if that fails will have to return it to Amazon
