Good PSU?


http://www.newegg.com/Product/Product.aspx?Item=N82E16817139011


This is for my new build:

Asus P8z68 Gen3 Pro motherboard
i5-2400
128GB SSD (I'm leaning towards Samsung) (w7+drivers)
350GB Velociraptor Sata II
1TB WD Caviar Black Sata II
SATA DVD-RW
24" LG 1080p LCD
Auzentech Forte sound card
z-5500 5.1 Digital speakers
16GB (ddr3-1600mhz 4x4Gb)
Video card TBD (maybe SLI or Crossfire)
Logitech Gaming keyboard and G500 mouse

Would it be wise to get a 900-950w PSU or is 850w more than enough for possible crossfire or SLI? I doubt I will overclock CPU, just use turbo boost.

It's not enough to handle CrossFireX of two Radeon HD 6990 or SLI of two GeForce GTX 590 graphics cards.

Determine which graphics card(s) you're expecting to run first.

That's my headache. I'm thinking of the 6950 (or crossfire) or 570 (or SLI) or wait for 79XX AMD or Nvidia's Kepler coming soon.

For a system running with two GeForce GTX 570 graphics cards in 2-way SLI mode a minimum 800 Watt or greater power supply with a combined +12 Volt continuous current rating of 56 Amps or greater and with at least four 6-pin PCI-Express Supplementary Power Connectors is recommended.

For a system running with two Radeon HD 6950 graphics cards in 2-way CrossFireX mode a minimum 700 Watt or greater power supply with a combined +12 Volt continuous current rating of 44 Amps or greater and with at least four 6-pin PCI-Express Supplementary Power Connectors is recommended.

The Corsair Professional Series HX850W (CMPSU-850HX), with its +12 Volt continuous current rating of 70 Amps and with its six 6+2-pin PCI-Express Supplementary Power Connectors is more than capable of handling either multiple card configuration with spare capacity to handle some overclocking.

I was going to say that you said no, it won't be enough but I saw, you said 6990 or 590. No, those were never in my thought process. Maybe get something a little less and then sell it when the next gen cards come out. I read about the new video cards coming soon and PCIe 3.0. I'm trying to take my time and see if they come out within the next few weeks.

I listed those two cards as examples of what the power supply that, you were considering, isn't able to handle.

Your original post mentions no graphics card models at all and yet you've chosen a power supply wattage and asked if it's "more than enough for possible crossfire or SLI".

My example showed that it's not enough for the specific cards I mentioned.

I'm also waiting to see what the new cards bring.

Yepp, I should of said that; I wasn't sure what to get but definitely not the 6990 or 590. Seems like I got time everything else I need to order are out of stock RAM/SSD.

The Black Friday & Cyber Monday specials must have depleted all of the stock.

Yeah, no kidding. Even Amazon is empty!
