Hi all. Ive had a look at some PSU calculators, but got vastly different results. What wattage will I need with this set up:

I5 4670K
ASUS Sabertooth Z87
NZXT Kraken X60
2 x 140mm case fans
1 x 120mm case fan
ASUS GeForce GTX 760
1 x Intel 530 180GB SSD
1 x 1TB WD Black HDD
2 x 8GB Corsair Vengeance Pro RAM
+other stuff

500 would probably cut, but I would go with 600 to have some extra headroom. Check out pcpartpicker.com their calculator is really good. Just make sure when you pick out your psu that you have enough wattage on the 12 volt rail to handle your gpu. Which won't be too tough because you're not really installing a super awesome card.

150W CPU (if overclocked) + 180W GPU (if overclocked) + 100W Other Stuff = 420W

Generally this system will hover around 350-400 in daily usage, lets be mean and call it 400W... generally a psu is at it's most ideal/efficient at 60%-70% load, so a 600W psu would be the "ideal" size for that system

A good quality 550w like the 550w XFX or if you are thinking of SLI later then 750w.
