I am building a desktop and im going to have intel i7 4770k CPU. A ASUS Z87 motherboard. G.Skill Ripjaws X Series 16GB (2X8GB). An Western Digital Caviar Green 2TB 3.5" 5400RPM Internal Hard Drive. A EVGA GeForce GTX 780 3GB ACX Video Card. In the Case of a Thermaltake Overseer RX-I ATX Full Tower. Any suggestions on what PSU i should have?

If you are planing to stick to a single GTX 780, 550W-650w is enough. Make sure that there is at least 40 Amps on the 12V rails.
Brands: Antec, XFX or Seasonic

Also having an HDD at 5400rpm as your only drive is really bad. Either consider that WD + ssd or get a black version at 7200.

There should be information on how much the amps are on the 12V rails. Essentially you are providing most of the power on 12V rails to your pc components. There should be a sticker on your actual PSU telling you the specs of it.

Example, XFX XTR 650W has 54 Amps on the 12V rails.
54 X 12 = 648W on the 12V rails.
