How many Watts do I need for my build?

I am building a new PC and I am lost on how many watts I should get in my PSU.

Intel Core i7 4770K 3.5GHz
ASUS GTX660-DC2O-2GD5 GeForce GTX 660 2GB 192-bit GDDR5
Toshiba 1TB 7,200 RPM SATA 6.0Gb/s 3.5
Toshiba HDTS112XZSWA 120GB SATA 6.0 Gb/s
MSI Z87-G41 PC Mate Socket LGA 1150 ATX
Crucial Ballistix Sport 16GB DDR3-1600 PC3-12800)
CD/DVD RW combo optical drive

Right now i have a 750 watt one in mind but I feel like that is way more than enough. Another worry, is the graphics card will have to be updated soon enough, but if I save enough money off of a lower watt PSU, than i might go for a 660ti graphics card. Anyway, let me know what you think!

Thank you!

More about watts build
  1. 550w should be plenty for your build, even if you do plan on sticking a 660ti in there.
  2. 550W or 650W should be sufficient.
  3. 550w PSU is enough for ur rig.
    Go with better brand like corsair, sesonic, xfx.
    I hope it helps.
    Thank you.
  4. go with 600 watts and if your overclocking 650 watts to keep a nice headroom. another thing go with i5-4670K insted of 4770K as they perform pretty much the same so its useless to spend 100$ extra for just HT. same thing with memory, go with 8GB to save some cash, and use the spending to buy yourself a GTX 770.
    is a nice PSU for the money [ about 75$ incl. shipping]
