New Build, Questions on PSU and MOBO

I have a few questions regarding a new build I want to make mostly regarding the PSU and MOBO, here are my current specs on what I want:

i5 2500k (i wish to do moderate OC-ing on this)

(currently looking at) MSI P67A-GD55 (B3) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard (any ideas on this would be great, or different mobo recommendations it just has to be CrossfireX ready with 2 x 16 PCI 2.0 or higher, i don't want to run x16 x8 x16 x16.

(currently looking at) Rosewill Bronze Series 1000w (i just need to know if i need this much to OC moderately and run my 6970s in crossfire and other specs)

16 GB (4 x 4GB) Mushkin Radioactive 1600mHz

CPU Cooler:
Cooler Master Hyper 212 plus Evo

2 x 6970 2GB Crossfirex

Seagate Barracuda 7200 RPM 1TB

OCZ 128Gb

This build is for heavy gaming, and heavy video editing so please any opinions on this or ideas for change-ups would be great, I am trying to keep it around $1200 because i need to buy a new monitor as well. Thank you in advance.

  1. There are no 16x/ 16x LGA 1155 motherboards . Well not with intel chip sets anyway .
    Maybe some with an added nVidia sb. But they dont seem to work that well

    Get a Z68 board . ALL of the features available
  2. You can crossfire that with a 900w

    I'd get a z68 motherboard. dual 8x is pretty good too as it will run both cards at %98 even if you get dual 16x, you won't notice the difference.
  3. Mobo: There is virtually no difference between x16 x16 and x8 x8 unless you run tri or quad sli. Go with a Z68 board in the $130-150 range. Highly suggest MSI Z68 GD55

    PSU: Go with Corsair or Seasonic PSU's. XFX and Antec are good quality too. For SLI 6970, an 80+ silver 850 watt is all you need with plenty of OC room too.

    RAM: 16GB is massive overkill. Go with 2x 4GB of 1600 mhz 1.5 volt ram.

    CPU Cooler: Very good choice. You can add a second fan for a ~10% increase in cooling.

    SSD: There are two things to look for with SSDs. Make sure it is SATA III, and if it uses a SandForce controller(Almost all do) make sure it is second generation. First generation sandforce is known to have a lot of problems. I prefer to avoid it all together and go with Crucial M4.
  4. The link below will show you how to accurately determine what PSU watts and amps. on the 12v rail are required for your current and future PC builds without guessing. You can also determine which PSUs are quality made as many Corsair, Antec, etc. are not the best quality.

    When it comes to SSDs, pretty much all the major brands including Crucial have had issues with either reliability or compatibility which is still being sorted out. Unless you can afford BSODs and lost data, you may want to wait awhile on an SSD purchase.,2998.html,13738.html

    The Hyper 212+ is a good, moderately priced HSF. The link below shows you how it compares to most of the popular HSFs.

    16 GB. of RAM is overkill unless you actually need it. It also makes it more difficult to OC should you decide to do so.

    My recommendation for performance and reliability is Gigabyte mobos based on my 20+ years of building high end PCs and having used all the major mobo brands.
