Is my current power supply enough for my upgrades

[djmj]

This is my first upgrade/build and I'm a little confused on if my current power supply is enough for my setup.

Old setup:

Processor: i7-920 2.66 GHz 8MB Cache
CPU Cooling: Asetek Single CPU Liquid Cooling System
Motherboard: ASUS P6T Deluxe LGA 1366 Intel X58 ATX Intel
Memory: Elpida 12GB (6 x 2GB) DDR3 1333MHz
Power Supply: Alienware 1000 Watt Multi-GPU Approved Power Supply
Graphics Processor: Single 1,792 MB NVIDIA GeForce GTX 295
Operating System: Windows 7 Ultimate (64-bit Edition)
System Drive: Single Drive Configuration - 300GB Velociraptor SATA 3.0Gb/s 10,000RPM 16MB Cache

New setup:

Processor: i7-980X Extreme Edition (12M Cache, 3.33 GHz OC’d to around 4.0 GHz)
CPU Cooling: Asetek Single CPU Liquid Cooling System
Motherboard: ASUS Rampage III Extreme LGA 1366 Intel X58
Memory: G.SKILL Trident+ Turbulence II 12GB (3 x 4GB) DDR3 2000 (PC3 16000)
Graphics Processor: Sapphire TOXIC HD 5970 4GB (900 MHz)
Power Supply: ???
System Drive: Single Drive Configuration - 300GB Velociraptor SATA 3.0Gb/s 10,000RPM 16MB Cache
Operating System: Windows 7 Ultimate (64-bit Edition)

The new Sapphire TOXIC HD 5970 4GB (900 MHz) says on their website it requires an 850watt power supply, but I'm not sure if that means plus the other hardware?

What do you think?

Get a better psu.

The power supply specs given by graphics card are always for the complete system. Check what the current rating on the 12V rails of your current PSU are, and what the combined power on the 12V rails is, dell units are usually pretty good but im not sure if higher power units are high quality.

Thanks for the reply. Here is a link to my power supply below with all the specs. Hope that will give you the info needed to help me out..

Combined 12V power output of 950W will be more than enough for it, you are good to go.

Thanks. Fixed original post. Still is Alienware N1000P-00 1000 Watt Multi-GPU Approved Power Supply unless proven that I need a larger supply. hunter315 is +1 that my current supply is fine. Waiting for more opinions...

I think that psu is made by Delta. From what I know it's a decent one. It's not high end by any means but should be plenty for your system. I would have no concerns using it if I had it.
