650W enough for this build?

First time builder here, and have what feels like a newb's question. For this build, is a 650W power supply sufficient?

1. XFX Double D HD-695X-CDFC Radeon HD 6950 2GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity
2. BIOSTAR TH67+ LGA 1155 Intel H67 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard
3. ASUS 24X DVD Burner
4. G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
5. Seagate Barracuda ST31000524AS 1TB 7200 RPM 32MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive
6. Intel Core i5-2500 Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 2000

Thanks for your help.

  1. Yes, Just make sure it is in the top 2 tiers. Such as Corsair TX, Gs or Seasonic, ect. Just google the one you think you want to buy and read the review.
    Your bould will be undre 400 Watts.
    My i5,2500k OCed to 4.2, with AMD 6870, 16 Gigs Ram and 4 drives is just under 300 Watts (measured 350 W at wall when runing Furmark)
  2. Thank you very much. Here is the power supply, fwiw.

  3. That is an excellent power supply, stable and safe, and will power your build easily.
  4. EXCELLENT Choice.
    I should have included "HX" models as recommended.
