  1. I got around 400W - 450W on somewhat maximum load, with a power supply calculator. Note that this was calculated without adding in any fans, any devices using usb ports, any aftermarket cooling, or any overclocked components. This is just a rough estimate of how much power your computer will need. I would suggest looking at different power supply calculators and try them out to see what you get.

    Here's the calculator I used: http://www.extreme.outervision.com/psucalculatorlite.jsp
    You can find many different calculators online by searching "power supply calculator"

    600w to 650w is a good range for your current specs.

  3. Keep in mind that if you plan on upgrading your computer later on, you'll need to buy a higher wattage power supply.
  4. Please not that you picked a 3770 not the 3770K. your board supports overclocking and your CPu doesn't. upgrade to a 3770k if you want to overclock
  5. ASUS Maximus V FORMULA LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 Extended ATX Intel Motherboard: 38 Watts

    Intel Core i7-3770 Ivy Bridge 3.4GHz (3.9GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000 BX80637I73770: 62 Watts

    CORSAIR Dominator Platinum 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 Desktop Memory Model CMD16GX3M4A1866C9: 12.6 Watts

    GIGABYTE GV-N770OC-2GD GeForce GTX 770 2GB 256-bit GDDR5 PCI Express 3.0 HDCP Ready WindForce 3X 450W Video Card: 232 Watts (Maximum when running FurMark stability testing)

    Western Digital WD Blue WD10EZEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive Bare Drive - OEM: 9.5 Watts

    Corsair Neutron Series GTX 2.5" 120GB SATA III Internal Solid State Drive (SSD): 0.35 Watts

    Corsair Obsidian 750D Black ATX Full Tower Computer Case: 27 Watts


    Total: 381.45 Watts

    As long as the PSU has a maximum combined +12 Volt continuous current rating of 34 Amps or greater and has at least one 6-pin and one 8-pin PCI Express supplementary power connectors then it should be able to do the job.
