I will be getting an intel i5

Avga gtx 770 super clocked

one 3 tb barracuda hard drive and one 1 tb barracuda hard drive

I will have 16 gigs of ram using for sticks

My motherboard is an MSI Computer Corp. Motherboard ATX DDR3 1333 LGA 1150 Motherboards Z87-G45 GAMING

My case is a NZXT guardian

I will also be getting an Samsung ssd 250 gbs

What power supply should I get?

GeForce GTX 770 SLI review - Power Consumption

Here is Guru3D's power supply recommendation:

GeForce GTX 770 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 770 2x SLI - On your average system the cards require you to have a 700~800 Watt power supply unit as minimum.
GeForce GTX 770 3x SLI - On your average system the cards require you to have a 1000~1200 Watt power supply unit as minimum.

an i5 system will use 120 - 170 watts depending on if you OC and how much voltage it takes (every chip is different) than add...

For a system using a single GeForce GTX 770 graphics card NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 42 Amps or greater and that has at least one 6-pin and one 8-pin PCI Express supplementary power connectors. Some of the non-reference design cards require two 8-pin PCI Express supplementary power connectors.

For a system using two GeForce GTX 770 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 850 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 59 Amps or greater and that has at least two 6-pin and two 8-pin PCI Express supplementary power connectors. Some of the non-reference design cards require two 8-pin PCI Express supplementary power connectors each so you'll need at least four 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

an i5 system will use 120 - 170 watts depending on if you OC and how much voltage it takes (every chip is different) than add the 402 watts for ~572 watts total. give yourself some overhead but don't go crazy . . .
