I am building a new PC and I cannot decide which of these 2 power supplies to get.

I am looking at a Rosewill 1000w (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)
Or
Thermaltake Toughpower 850W (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)

Here is what I am putting into the system

Motherboard: ASUS Sabertooth 990FX
CPU: AMD FX-8350 Vishera 4.0GHz
Heatsink: Phanteks PH-TC14PE
RAM: G.Skill (4x4GB)
HD: 2x 1TB 7200RPM
Video: 2x SAPPHIRE 100355OCL Radeon HD 7850 2GB 256-bit GDDR5

I like the Thermaltake but I'm not sure if the 850 would be enough.
Thanks

For this PC a 600w PSU will be more than enough. Don't spend so much money on it. Go for quality and not quantity. Pic a good brand like Corsair, Sesonic, Antec, Enermax.

Sorry, you are making a HUGE mistake with the CF 7850's. First of all, the weaker, older cards simply don't do too well in crossfire/SLI. Second, AMD got caught red handed with phoney CF software. Meaning, for many games they simply crank out the frames as fast as possible and if the two cards put out a frame at about the same time, they output them both at once, giving you the infamous "runt" frames. AMD as been working on this and promising new drivers for at least half a year and they aren't there yet. Nvidia has been on this for YEARS and does a great job, giving up the artificially inflated FPS to get more evenly spaced frames.

Also there are other issues with CF/SLI like not all games work with them etc.

The rule of thumb is for a new build, get the fastest card you can, then go SLI/CF a year or two later.

7850's cost $150 to $200 so you could get a $350 - $400 card. If you want to stay in Radeon, you can get a 7970 card that will give you much more than pathatic CF 7850's.

If you want to cross the aisle, $400 is just enough to get a GTX770 which will blow you away.

Yes, I'd get a 850W supply for future SLI/CF. Go with something like this:

Pumps out up to 70 amps on the all important +12V supply.

For a system using two AMD reference design Radeon HD 7850 graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 600 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 39 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors. Some of the non-reference design Radeon HD 7850 graphics cards require at least two 6-pin PCI Express supplementary power connectors for each graphics card so the power supply should have at least four 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I thought the 7850 were still a decent card. Guess I should say that I would be running Windows 8, are there any driver problems with that card. I have 2 4850's in my current system and I cant run CF with Windows 8

Read the one star reviews for that board, sort of scary, a lot of fan noise. The problem is, all the 7970's suffer from this. The GTX 770 is a brand new board that is faster. Please go with it.

Thanks for all the help, kinda dissapointed that AMD has so many problems with their cards. I have always been a big Radeon fan. That being said the 770's do look pretty slick and have good reviews so far. So now I am stuck between which of these two cards I want to get.

I was going to ask you why you bought an Asus Sabertooth when it is well known that the motherboard cover collects dust and doesn't help at all with heat. Then I saw that the AMD Sabertooth doesn't have that full-board shroud.

If he does buy this setup, be sure to overclock it!

You, being a moderator, are probably pretty much up on things. Is there any truth that the new "black" 8350 that runs at 5GHz will be $900+ dollars?

How easy is it to overclock this CPU? I have messed with TurboV that came with the MB that I have now and that seemed pretty easy. Oh and do you have any clearance issues with that Heatsink and the RAM?

The Scythe Slip Stream 120mm x 25mm Fan uses a nine-bladed design to achieve remarkable near 4:1 Airflow to Noise ratios! The Slip Stream's aerodynamic design grants it 20 ~ 40% more airflow that similar fans. It can connect with either 3-pin or a 4-pin power connector.

You just have to change the position of the anti-vibration strips , to fit for the 120 fans.

The stock fans are cool , but these cool better by 4 degrees.
